Math Practice TEAS Test

Correct Answer: A

Rationale: The correct answer is A: x + 4 = 5/6y - 2. To break it down step-by-step: 1. "Four more than a number" translates to x + 4. 2. "2 less than 5/6 of another number" translates to 5/6y - 2. 3. Combining the two expressions gives x + 4 = 5/6y - 2, which represents the given relationship accurately. In summary, choice A is correct because it correctly captures the relationship described in the question. Choices B, C, and D are incorrect because they do not accurately represent the relationship between the two numbers given in the question.

Correct Answer: B

Rationale: The correct answer is B: Low positive correlation. This is because the data shows a general increasing trend, but the points are scattered and do not form a tight linear relationship. The correlation coefficient would be closer to 0 than to +1, indicating a weak positive correlation. Choices A and C are incorrect as they suggest stronger correlations, which is not supported by the data. Choice D is incorrect as there is some level of relationship between the variables, even if it is weak.

Correct Answer: B

Rationale: The correct answer is B: 16 ounces. There are 16 ounces in a pound because this is the standard conversion rate between ounces and pounds. To arrive at this conversion, we can use the fact that 1 pound is equal to 16 ounces. Therefore, if you have 1 pound and you want to convert it to ounces, you would multiply 1 pound by 16 ounces/pound, which gives you 16 ounces. Summary of other choices: A: 8 ounces - This is incorrect because 8 ounces is half of a pound, not the full conversion rate. C: 32 ounces - This is incorrect because 32 ounces is actually equivalent to 2 pounds, not 1 pound. D: 12 ounces - This is incorrect as it is not the standard conversion rate between ounces and pounds.

Correct Answer: C

Rationale: To find the percentage of the time Cora did not fall, we subtract the number of times she fell (20) from the total times she skated (27). So, 27 - 20 = 7 times she did not fall. Then, we divide the number of times she did not fall (7) by the total times she skated (27), which is 7/27 ≈ 0.26 or 26%. Therefore, the correct answer is C. Choice A, B, and D are incorrect because they do not accurately represent the percentage of the time Cora did not fall based on the given information.

Correct Answer: B

Rationale: To find the total height when stacked, we add the heights of the two bookcases. 32.75 inches + 17.25 inches = 50 inches Therefore, the correct answer is B (50 inches). Explanation for incorrect choices: A: 49.5 inches is incorrect because the heights are added, not averaged. C: 48 inches is incorrect as it's less than the sum of the two heights. D: 51 inches is incorrect as it's greater than the sum of the two heights.
