Cevap: Vehicle V-102 qualifies for a total rebate of $5,000.; Vehicle V-103 receives a lower total rebate than Vehicle V-101.; Vehicle V-101 and Vehicle V-102 receive identical base rebates before battery bonuses are considered.

Cevap

The correct statements are the ones indicating that Vehicle V-102 qualifies for a total rebate of $5,000; Vehicle V-103 receives a lower total rebate than Vehicle V-101; and Vehicle V-101 and Vehicle V-102 receive identical base rebates before battery bonuses are considered.
Synthesizing the policy terms in Tab 1 with the vehicle log in Tab 2 yields precise rebate totals. Vehicle V-102 receives 4,000base(Q2)+4,000 base (Q2) + 1,000 battery bonus = 5,000total.VehicleV103receives5,000 total. Vehicle V-103 receives 2,000 total, which is less than Vehicle V-101 (4,000total).Furthermore,bothV101(Q1)andV102(Q2)sharethesame4,000 total). Furthermore, both V-101 (Q1) and V-102 (Q2) share the same 4,000 base rebate structure prior to battery bonus additions.

The following three sources provide details regarding a Phase II clinical trial for a new therapeutic candidate:

Tab 1: Clinical Trial Protocol (Section 3.2)
Subjects in Arm A are scheduled to receive a daily dose of 50 mg50\text{ mg} of Active Drug X for 14 consecutive days14\text{ consecutive days}, followed immediately by a 7-day7\text{-day} washout period during which 0 mg0\text{ mg} of medication is administered. Subjects in Arm B receive a matching placebo daily for 21 consecutive days21\text{ consecutive days}.

Tab 2: Central Pharmacy Dispensing Log
During the 21-day trial window, the central pharmacy logged a total cumulative dosage of 700 mg700\text{ mg} of Active Drug X dispensed per subject in Arm A, and 0 mg0\text{ mg} dispensed per subject in Arm B.

Tab 3: Independent Auditor Compliance Report
The compliance audit reveals that subjects in Arm A logged active pill ingestion on each of the 21 days21\text{ days} of the trial window, recording no days with zero medication intake.

Which of the following statements, if true, would help explain or resolve the apparent discrepancy between the protocol specification, the pharmacy dispensing logs, and the auditor's compliance report? Select all that apply.

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: Arm A subjects ingested a reduced daily dose of approximately 33.3 mg33.3\text{ mg} per day evenly over all 21 days rather than 50 mg50\text{ mg} per day for 14 days.; The central pharmacy pre-packaged the 700 mg700\text{ mg} total allocation into 21 lower-dose daily capsules instead of 14 standard-dose capsules.

Cevap

The discrepancy is resolved by options stating that subjects ingested approximately 33.3 mg per day across all 21 days, or that the pharmacy pre-packaged the 700 mg allocation into 21 lower-dose daily capsules.
The correct options present scenarios where the total active drug allocation of 700 mg (from the pharmacy logs) is spread across all 21 trial days (from the compliance audit), resulting in a lower daily dosage of approximately 33.3 mg per day. This reconciles the 21 active ingestion days with the 700 mg total quantity dispensed.

Adım Adım Çözüm

1
Identify the conflict between the sources.
Tab 1 prescribes 50 mg/day×14 days=700 mg50\text{ mg/day} \times 14\text{ days} = 700\text{ mg} plus a 7-day washout (0 mg/day). Tab 2 confirms a total of 700 mg700\text{ mg} dispensed for Arm A. Tab 3 shows active ingestion on all 21 days (0 washout days).
To resolve the conflict, any valid hypothesis must account for 21 active days of ingestion while keeping the total active drug amount at 700 mg700\text{ mg}.
2
Evaluate hypotheses regarding daily dose re-apportionment.
Dividing 700 mg700\text{ mg} by 21 days yields 70021=33.33 mg/day\frac{700}{21} = 33.33\text{ mg/day}.
If subjects took 33.3 mg\approx 33.3\text{ mg} per day for 21 days, or if the pharmacy packaged 700 mg700\text{ mg} into 21 daily capsules, both Tab 2 (700 mg700\text{ mg} total) and Tab 3 (21 active days) are satisfied.

In City Y, between 2018 and 2023, the proportion of all daily commuter trips taken via the municipal subway system increased from 20 percent to 30 percent. During this same five-year period, the total number of daily commuter trips taken across all modes of transportation in City Y decreased by 40 percent.

If the statements above are true, which of the following conclusions must also be true regarding daily commuter trips in City Y from 2018 to 2023?

Cevabı ve açıklamayı göster

Cevap: The total number of daily commuter trips taken via the municipal subway system was lower in 2023 than in 2018.

Cevap

The total number of daily commuter trips taken via the municipal subway system was lower in 2023 than in 2018.
The correct option is derived directly through exact percentage calculations. By establishing total 2018 daily commuter trips as TT, subway trips accounted for 20%20\% of TT, or 0.20T0.20T. Because total trips across all modes dropped by 40%40\% by 2023, total trips in 2023 equaled 0.60T0.60T. In 2023, subway trips accounted for 30%30\% of this reduced total (0.30×0.60T=0.18T0.30 \times 0.60T = 0.18T). Comparing 0.18T0.18T to 0.20T0.20T demonstrates a logical and mathematically inescapable reduction in total subway trips.

Adım Adım Çözüm

1
Define an initial baseline for total daily commuter trips.
Let the total number of daily commuter trips in 2018 be represented as TT.
Establishing a baseline variable allows quantitative comparisons across years.
2
Calculate the absolute number of subway trips in 2018.
Subway trips in 2018 = 0.20×T=0.20T0.20 \times T = 0.20T.
The passage states that 20 percent of all commuter trips were taken via subway in 2018.
3
Determine the total number of daily commuter trips in 2023 after the specified decrease.
Total trips in 2023 = T×(10.40)=0.60TT \times (1 - 0.40) = 0.60T.
The total number of daily commuter trips across all modes decreased by 40 percent.
4
Calculate the absolute number of subway trips in 2023 and compare with 2018.
Subway trips in 2023 = 0.30×0.60T=0.18T0.30 \times 0.60T = 0.18T. Since 0.18T<0.20T0.18T < 0.20T, absolute subway trips decreased.
Comparing 0.18T0.18T to 0.20T0.20T shows a net decrease in absolute subway trip volume.

Tab 1: Executive Summary Memo
Apex Logistics management claims that replacing 40% of its delivery fleet with electric vehicles (EVs) in 2025 was the direct cause of the overall reduction in annual fleet operating expenses. The memo asserts: "Because electric vehicles incur substantially lower energy costs per mile and require minimal routine maintenance, transitioning 40% of our fleet to EVs produced our operational cost savings for 2025."

Tab 2: Fleet Operating Metrics

Cevabı ve açıklamayı göster

Cevap: The 33% decline in market diesel fuel prices from 4.50to4.50 to 3.00 per gallon accounted for fuel savings on the remaining diesel vehicles that exceeded the total net reduction in fleet expenditures.

Cevap

The statement showing that the 33% decline in market diesel fuel prices from 4.50to4.50 to 3.00 per gallon accounted for fuel savings on the remaining diesel vehicles that exceeded the total net reduction in fleet expenditures.
The correct answer demonstrates that an external macroeconomic factor—the 33% reduction in diesel fuel prices from 4.50to4.50 to 3.00 per gallon—accounts for the savings on the remaining diesel vehicles. This provides a strong alternative explanation for the drop in total expenditure, thereby directly weakening management's claim that EV adoption caused the cost savings.

Adım Adım Çözüm

1
Identify the core argument in Tab 1
Management claims that converting 40% of the fleet to EVs directly caused the total fleet operating expense reduction in 2025 due to EV efficiency and low maintenance.
To weaken a causal claim, we must find an alternative explanation or evidence that the stated cause did not produce the observed effect.
2
Analyze quantitative changes in Tab 2 across the two years
Maintenance barely changed (300kto300k to 295k), while fuel/energy dropped from 900kto900k to 725k (a 175kdrop).Dieselpricepergallondroppedsignificantlyfrom175k drop). Diesel price per gallon dropped significantly from 4.50 to $3.00.
Comparing metrics reveals where the actual dollar savings originated.
3
Evaluate the impact of external diesel price drops on the total savings
The 600,000 diesel miles driven in 2025 benefited from a $1.50 per gallon price drop. This macro price reduction explains the fuel savings regardless of EV implementation.
Showing that an external factor (diesel market price collapse) caused the savings severely weakens the claim that EV adoption was the cause.

Many urban transit advocates argue that expanding municipal light rail networks inevitably reduces highway traffic congestion by drawing drivers off major roadways. However, recent mobility studies demonstrate that new rail lines often induce outer-suburban residential development, ultimately generating additional automobile trips onto regional highways. Although light rail projects unquestionably provide essential mobility options for residents who lack personal vehicles, the core premise that such systems alleviate highway gridlock is demonstrably false. Therefore, municipal transportation authorities should not approve funding for light rail expansions when the sole justification provided is congestion reduction.

Passage:
During the early Levant Bronze Age, the transition from unalloyed copper to arsenical bronze marked a critical shift in regional metallurgy. Early smelting workshops relied on localized copper ores with variable arsenic impurity levels. Scholars initially hypothesized that early smiths deliberately added arsenic-rich minerals to enhance the metal's hardness. However, recent isotopic analyses of local slag heaps indicate that furnace temperatures were insufficient to volatilize arsenic from secondary mineral additives. Instead, the presence of arsenical copper in early artifacts corresponds directly to natural variations in the mineralogical composition of localized ore strata extracted across distinct mining phases.

Later in the period, the adoption of tin bronze necessitated long-distance trade networks, as usable tin deposits were entirely absent from the Levant. Unlike arsenical copper artifacts, which varied in composition according to local ore layers, tin bronze objects from this later phase display a highly uniform ratio of tin to copper across distant urban settlements. Archaeologists attribute this compositional standardization to the emergence of centralized municipal authorities that managed the procurement and distribution of imported tin. Consequently, while the composition of early arsenical copper was governed chiefly by regional geological variation, the consistent quality of later tin bronze depended on institutional mechanisms for managing external trade.

Based on the passage above, is the following statement True or False?

Statement: The contrast in compositional consistency between early arsenical copper artifacts and later tin bronze artifacts reflects a transition from metallurgical outcomes governed by localized geological variations to those regulated by centralized institutional distribution.

Cevabı ve açıklamayı göster

Cevap: True

Cevap

True. The passage indicates that early arsenical copper composition was determined by localized ore strata variations, whereas later tin bronze uniformity was managed by centralized municipal authorities.
The statement accurately synthesizes findings from across both paragraphs of the passage. The first paragraph explains that variations in early arsenical copper artifacts resulted from natural mineralogical differences in local ore deposits. The second paragraph attributes the standardization of later tin bronze artifacts to centralized municipal administration of imported tin trade. Combining these distinct details confirms that metallurgical consistency evolved from being constrained by regional geology to being regulated by institutional distribution.

Adım Adım Çözüm

1
Analyze the passage's explanation of early arsenical copper composition.
Paragraph 1 demonstrates that variations in arsenical copper artifacts were caused by natural differences in local ore strata extracted across mining phases.
Establishing the cause of compositional variability in early artifacts provides the first half of the synthesized comparison.
2
Analyze the passage's explanation of later tin bronze composition.
Paragraph 2 demonstrates that the uniform ratio in tin bronze artifacts across settlements was driven by centralized municipal authorities managing imported tin.
Establishing the cause of standardization in later artifacts provides the second half of the synthesized comparison.
3
Synthesize the findings from both paragraphs to evaluate the statement.
The shift in compositional consistency directly corresponds to the transition from outcomes driven by localized geological factors to those managed by centralized institutional distribution, validating the statement as True.
Combining evidence across non-contiguous sections of the passage confirms the truth of the statement.

In marine archaeology, underwater sonar mapping has traditionally been restricted to shallow coastal waters because deep-sea acoustic signals decay rapidly. Recently, oceanographers developed low-frequency sonar transducers that transmit data across immense oceanic depths without significant signal degradation. Some archaeologists argue that this technological breakthrough will immediately render deep-sea robotic excavations obsolete. However, sonar mapping only identifies surface anomalies on the seabed rather than excavating buried artifacts. Therefore, deep-sea robotic submersibles will remain essential for underwater archaeological retrieval.

In the argument presented, what role does the claim that underwater sonar mapping has traditionally been restricted to shallow coastal waters play?

Historians of science often claim that the rapid adoption of early industrial machinery was driven primarily by shortages of skilled manual labor. However, recent archival evidence indicates that factory owners chose mechanized equipment largely to ensure standardized product quality rather than to cut labor headcount. Consequently, the traditional view oversimplifies the economic motivations behind nineteenth-century industrialization. Although early machines did occasionally reduce the need for specialized artisans, the primary financial incentive remained product uniformity.

In the argument above, the two boldface portions play which of the following roles?

Cevabı ve açıklamayı göster

Cevap: The first is a position that the argument seeks to refute; the second is the main conclusion of the argument.

Cevap

The correct answer states that the first boldface portion is a position that the argument seeks to refute, while the second boldface portion is the main conclusion of the argument.
The correct answer accurately identifies the role of both statements: the first boldface statement introduces an established historical claim that the passage proceeds to counter with archival evidence, and the second boldface statement asserts the main conclusion reached by the author.

Adım Adım Çözüm

1
Analyze the first boldface portion within context
The statement 'the rapid adoption of early industrial machinery was driven primarily by shortages of skilled manual labor' represents a historical claim introduced by 'Historians... often claim'. The transition word 'However' immediately following it indicates that the author disputes this claim.
Identifying transition words helps establish whether a claim represents the author's voice or an opposing viewpoint.
2
Analyze the second boldface portion within context
The statement 'the traditional view oversimplifies the economic motivations behind nineteenth-century industrialization' is introduced by the conclusion indicator 'Consequently' and represents the ultimate claim the author derives from the archival evidence.
Conclusion indicators signal the central thesis that the surrounding premises aim to justify.
3
Synthesize the relationship between the two claims
The argument refutes the traditional historical claim (first boldface) in order to establish its main conclusion (second boldface).
Matching the structural relationship to the correct option confirms the accurate description of argument flow.

An agricultural research team conducted a five-year study across 30 coffee-growing districts to investigate the relationship between shade-tree canopy coverage and outbreaks of coffee leaf rust, a devastating fungal disease. The researchers observed that farms maintaining a dense shade canopy (>50% coverage) experienced a 60% lower incidence of fungal rust compared to full-sun farms (<10% coverage). Based on these observational findings, the head researcher hypothesized that the dense canopy directly creates a microclimate that inhibits the germination of fungal rust spores. From the options provided, select the statement that most strongly strengthens the head researcher's causal hypothesis for Column 1, and select the statement that most strongly weakens the causal hypothesis by providing an alternative explanation for Column 2.

Cevap

For Column 1 (Strengthens), the correct choice is the statement confirming controlled laboratory evidence that shade microclimates directly prevent fungal spore germination. For Column 2 (Weakens), the correct choice is the statement revealing that shade-canopy farmers applied double the frequency of fungicides, providing a confounding alternative cause for the reduced infection rate.
The causal hypothesis asserts that dense shade canopy microclimates directly inhibit fungal rust spore germination. The statement providing controlled laboratory evidence that shade microclimates prevent germination directly verifies the proposed physiological mechanism, strongly strengthening Column 1. Conversely, the statement revealing that shade-canopy farmers applied twice as much fungicide provides a plausible alternative explanation for the lower rust rates, effectively weakening the causal claim for Column 2.

Adım Adım Çözüm

1
Analyze the core argument and hypothesis in the stem.
Premise: High canopy farms have 60% lower rust incidence than full-sun farms. Hypothesis: Dense canopy shade directly creates a microclimate that inhibits fungal spore germination.
Understanding the precise causal link (shade microclimate -> reduced spore germination) is essential to evaluate strengthening and weakening statements.
2
Evaluate candidate statements for Column 1 (Strengthens).
The statement regarding controlled laboratory trials proves that the light and temperature conditions under shade directly stop spore germination, ruling out coincidental correlation and confirming the causal mechanism.
Direct experimental confirmation of the proposed mechanism strengthens a causal hypothesis.
3
Evaluate candidate statements for Column 2 (Weakens via alternative explanation).
The statement noting that shade-canopy farmers used twice as much fungicide introduces a confounding variable (fungicide treatment), which explains the lower rust levels without requiring shade microclimate to be the cause.
An alternative cause that accounts for the observed effect severely weakens the claim that shade microclimate was the driving factor.

Passage:
In recent years, semiconductor foundries have increasingly relied on extreme ultraviolet (EUV) lithography to print sub-seven-nanometer circuit patterns onto silicon wafers. However, EUV systems require mirrors coated with dozens of alternating layers of molybdenum and silicon, manufactured to atomic-level precision, to reflect light at a wavelength of 13.5 nanometers. Because these mirrors degrade quickly under intense ultraviolet exposure, foundries must replace them far more frequently than the optics used in older deep ultraviolet (DUV) systems. Despite these frequent replacements and the soaring operational costs associated with maintaining ultra-clean vacuum environments for EUV equipment, top-tier foundries have consistently reported higher net profit margins on EUV-fabricated chip batches than on DUV-fabricated batches of equivalent volume. Economists attribute this phenomenon to the significantly higher transistor density achieved via EUV lithography, which enables semiconductor designers to cram more processing power into smaller dies, allowing microchip vendors to command premium pricing that more than offsets the elevated capital and maintenance expenses borne by the foundries.

Statement: Based on the passage, the higher profit margins of EUV-fabricated chip batches depend on premium market pricing enabled by greater transistor density rather than lower maintenance overhead.

Cevabı ve açıklamayı göster

Cevap: True

Cevap

True. The passage premises establish that EUV systems incur higher maintenance costs, but achieve superior net profit margins because greater transistor density allows vendors to charge premium prices that exceed those additional operational costs.
The passage explicitly states that EUV equipment involves higher capital and maintenance costs (such as frequent mirror replacements) compared to DUV systems. It directly attributes the higher profit margins of EUV chips to the premium prices enabled by higher transistor density, which offsets these elevated costs. Therefore, the statement logically follows from the premises.

Adım Adım Çözüm

1
Identify the passage premises regarding EUV maintenance costs and profitability.
EUV systems require more frequent mirror replacements and higher operational expenses than DUV systems, yet yield higher net profit margins.
Establishing the contrast between maintenance costs and net margins is required to evaluate what drives profitability.
2
Examine the logical mechanism given for why EUV batches are more profitable.
Economists explain that higher transistor density permits smaller dies with more processing power, commanding premium pricing that more than offsets the elevated maintenance expenses.
This establishes that premium pricing from density, not low maintenance overhead, is the cause of higher margins.
3
Assess the truth value of the statement against the synthesized premises.
The statement accurately reflects that higher profit margins depend on premium pricing from transistor density rather than lower maintenance overhead.
Direct logical alignment with the passage premises confirms the statement is True.

Dr. Vance: To protect rare historical manuscripts from ambient humidity, the central archive should immediately install industrial dehumidifiers. Just as sealed glass display cases preserve delicate oil paintings in museums by maintaining a rigid microclimate, controlling humidity across our entire facility will ensure the long-term survival of these paper artifacts.

Dr. Kim: However, sealed glass cases regulate tiny, enclosed volumes of air, whereas industrial dehumidifiers in vast facilities draw in variable external air, creating localized moisture spikes that accelerate paper warping.

Cevap: Demonstrating that an analogy relied upon to justify a policy fails because of a critical difference in operating scale and mechanism.

Cevap

Demonstrating that an analogy relied upon to justify a policy fails because of a critical difference in operating scale and mechanism.
Dr. Vance attempts to justify a facility-wide humidity control policy by drawing a direct analogy to sealed museum display cases. Dr. Kim counters this argument by establishing a critical distinction between the two scenarios: sealed cases control tiny, isolated air volumes, whereas facility dehumidifiers process fluctuating ambient air in large spaces. By demonstrating that this difference in scale and mechanism produces harmful moisture spikes, Dr. Kim shows that the underlying analogy fails to support the proposed action.

Adım Adım Çözüm

Dr. Vance proposes installing industrial dehumidifiers for an entire facility, relying on an analogy to sealed glass cases that preserve paintings.
Identifying the premise-argument structure and the comparative analogy is essential to understanding the strategy being attacked.
2
Analyze the second speaker's rebuttal technique
Dr. Kim points out that sealed glass cases operate on small enclosed volumes, whereas industrial dehumidifiers operate in large open spaces with fluctuating outside air, leading to moisture spikes.
This establishes that Dr. Kim is identifying a key functional breakdown between the source case (glass cases) and the target case (facility-wide system).

Cevap: Departments with the highest platform adoption rates experienced the largest percentage decreases in dispute escalations, whereas departments with negligible platform activity saw no change in escalation rates.; Simultaneously with the platform's launch, executive management instituted a strict policy that penalized department heads whose teams failed to resolve disputes internally before escalating them.

Cevap

The two correct findings are: (1) the statement establishing that departments with higher adoption rates experienced larger decreases in escalations while inactive departments saw no change (Strengthener), and (2) the statement noting that executive management simultaneously instituted penalties for escalating disputes internally (Alternative Explanation / Weakener).
The causal argument claims that the peer appreciation platform caused a 35% drop in escalated disputes. The finding regarding adoption rates by department strengthens the argument by demonstrating a clear dose-response relationship between platform use and dispute reduction. The finding regarding executive penalties for escalated disputes weakend the argument by introducing a simultaneous, independent policy change that plausibly accounts for the decrease in escalations without requiring the platform's intervention.

Adım Adım Çözüm

1
Identify the core causal argument in the prompt stem.
Premise: Peer recognition platform launched; dispute escalations dropped 35% six months later.
Conclusion: The platform directly caused the drop in escalations by fostering cross-team goodwill.
Evaluating a causal claim requires separating the observed event (correlation) from the inferred causal mechanism.
2
Evaluate candidate findings for a logical strengthener.
The statement showing a direct dose-response relationship (higher platform usage correlates with greater escalation drops across departments) eliminates key background noise and reinforces that the platform itself drives the effect.
Concomitant variation across controlled sub-groups provides strong empirical support for a causal relationship.
3
Evaluate candidate findings for a logical weakener / alternative explanation.
The statement detailing a simultaneous management policy penalty provides an alternate reason why escalations dropped (managers suppressed escalations to avoid penalties), undermining the claim that goodwill was the driver.
An unaddressed external factor introduced at the same time offers a competing explanation for the exact same outcome.

Causal Reasoning in Two-Part Analysis (Strengthening vs. Alternative Explanations)
Soru 99Soru

[Tab 1: Commercial Lease Termination Policy]
Standard commercial leases require tenants to pay a base termination penalty of 30,00030,000 USD if cancelled prior to the lease expiration date. However, the base penalty is reduced by 50%50\% if the tenant provides at least 120120 days of advance written notice AND has maintained an active tenancy for at least 3636 consecutive months without any late rent payments.

[Tab 2: Penalty Exemptions & Fees]
Special Exception Clause E-4: If a lease is terminated due to corporate downsizing, the base termination penalty is waived entirely, provided that the tenant pays a administrative closing fee of 5,0005,000 USD and yields the premises in move-in condition. If Clause E-4 applies, all other penalty reductions or notices under Tab 1 are superseded and do not stack.

[Tab 3: Account Record - Vertex Solutions]
- Initial Lease Commencement: January 1, 2023
- Termination Notice Date: November 1, 2025 (Effective Termination Date: March 1, 2026)
- Reason for Termination: Corporate Downsizing under Clause E-4
- Payment History: 11 late payment recorded in August 2024
- Premises Condition: Satisfactory (Move-in condition)

Statement to evaluate: Based on the policy guidelines and account record across all three tabs, Vertex Solutions is required to pay a final net termination charge of exactly 5,0005,000 USD to cancel its lease on March 1, 2026.

Cevabı ve açıklamayı göster

Cevap: True

Cevap

True
The statement is True because Special Exception Clause E-4 in Tab 2 explicitly supersedes the general rules in Tab 1 whenever a lease termination is caused by corporate downsizing. Under Clause E-4, the base 30,00030,000 USD penalty is completely waived in favor of a flat 5,0005,000 USD administrative closing fee, provided the premises are yielded in move-in condition (which Tab 3 confirms). Consequently, neither the late payment in August 2024 nor the Tab 1 notice rules alter the final fee of 5,0005,000 USD.

Adım Adım Çözüm

1
Identify the primary governing policy rule for the scenario.
Vertex Solutions is terminating due to corporate downsizing, bringing the case under Special Exception Clause E-4 in Tab 2.
Tab 2 dictates that Clause E-4 applies specifically to corporate downsizing terminations.
2
Evaluate the conditions and conflict/superseding provisions under Clause E-4.
Clause E-4 waives the 30,00030,000 USD base penalty and requires only a 5,0005,000 USD administrative closing fee, superseding Tab 1 rules.
The premises condition is recorded as satisfactory (move-in condition), fulfilling the requirement for Clause E-4.
3
Assess whether Tab 1 disqualifiers (e.g., late payments) apply.
The late payment in August 2024 does not affect Clause E-4 because Clause E-4 explicitly supersedes Tab 1 conditions.
Tab 2 explicitly states: 'If Clause E-4 applies, all other penalty reductions or notices under Tab 1 are superseded'.

What is the sum of all real solutions to the equation (x3)2=4(x3)(x - 3)^2 = 4(x - 3)?

Cevabı ve açıklamayı göster

Cevap: 10

Cevap

The sum of all real solutions to the equation is 10.
To find all solutions to (x3)2=4(x3)(x - 3)^2 = 4(x - 3), bring all terms to the left side: (x3)24(x3)=0(x - 3)^2 - 4(x - 3) = 0. Factoring out (x3)(x - 3) yields (x3)(x7)=0(x - 3)(x - 7) = 0. This gives two distinct real roots, x=3x = 3 and x=7x = 7. Adding these together yields a sum of 10.

Adım Adım Çözüm

1
Rearrange the given equation so that all terms are on one side.
(x3)24(x3)=0(x - 3)^2 - 4(x - 3) = 0
Moving all terms to one side allows for factoring without losing variable solutions.
2
Factor out the common algebraic factor (x3)(x - 3).
(x3)[(x3)4]=0    (x3)(x7)=0(x - 3)\,[(x - 3) - 4] = 0 \implies (x - 3)(x - 7) = 0
Factoring avoids the mistake of dividing by a variable expression.
3
Set each factor equal to zero to find the real roots.
x3=0    x=3x - 3 = 0 \implies x = 3 and x7=0    x=7x - 7 = 0 \implies x = 7
A product of factors equals zero if and only if at least one factor is zero.
4
Calculate the sum of the real solutions.
3+7=103 + 7 = 10
The question asks for the sum of all distinct real solutions.
