Practice Math TEAS TEST

Correct Answer: B

Rationale: To find the sale price of the sweater marked 15% off, you first calculate the discount amount by multiplying $78 by 15% (0.15), which equals $11.70. Then deduct this discount from the original price: $78 - $11.70 = $66. Therefore, choice B ($66) correctly estimates the sale price. Choice A ($12) is too low and does not consider the 15% discount. Choice C ($22) is also too low and does not account for the correct discount amount. Choice D ($69) is close but does not reflect the correct calculation after the 15% discount.

Correct Answer: D

Rationale: Step 1: Let x be the original price of the recliner. Step 2: Sale price = x - 0.3x = 0.7x Step 3: Price after coupon = 0.7x - 0.25(0.7x) = 0.525x Step 4: Set up equation: 0.525x = 237 Step 5: Solve for x: x = 237 / 0.525 ≈ $451 Step 6: The original price is closest to $451, making option C incorrect. Step 7: Check why other choices are incorrect: - Option A: $316 is too low for the original price. - Option B: $431 is the calculated sale price, not the original price. - Option D: $527 is the original price based on the calculation.

Correct Answer: D

Rationale: The correct answer is D: No correlation. This is because the scatter plot does not show a clear pattern or trend between exam scores and heights. There is no apparent increase or decrease in one variable as the other variable changes. It indicates that there is no relationship between the two variables. Choice A (Positive) is incorrect because there is no consistent upward trend in the data points. Choice B (Positive and Negative) is incorrect as there is no presence of both positive and negative correlations simultaneously. Choice C (Negative) is incorrect since there is no consistent downward trend in the data points. The absence of any clear trend or pattern indicates a lack of correlation, making choice D the correct answer.
