ATI TEAS Math Practice Test

Correct Answer: C

Rationale: To earn more than 96 points, Mathew needs to answer at least 97 points out of 120 (40 questions * 3 points each). This means he can only get a maximum of 23 questions wrong (120 - 97 = 23). So, Mathew can answer up to 7 questions incorrectly (23/3 = 7.67, rounded down to 7) and still qualify for varsity sports. Therefore, the correct answer is C: 0 ≤ x < 8, as Mathew can answer 0 to 7 questions incorrectly and still meet the eligibility requirement. Choices A, B, and D are incorrect because they do not accurately reflect the maximum number of questions Mathew can answer incorrectly based on the total points needed for eligibility.

Correct Answer: C

Rationale: The independent variable is the variable that is manipulated or controlled by the researcher. In this case, the number of nurses in various specialties is the variable that is being studied and is not dependent on any other variable. Therefore, the correct answer is C - Nurse specialties. Choices A, B, and D are incorrect as they are either specific specialties or the dependent variable (number of nurses).

Correct Answer: B

Rationale: To simplify the expression 3(1/6) - 1(5/6), we first multiply the whole number by the fraction: 3 * 1/6 = 3/6. Then, we subtract 1 * 5/6 = 5/6. Simplifying 3/6 - 5/6 gives us -2/6, which reduces to -1/3 or 1 (1/3). Therefore, the correct answer is B: 1 (1/3). Choice A: 2 (1/3) is incorrect as the result is negative. Choice C: 2 (1/9) is incorrect as it is not the simplified form. Choice D: 5/6 is incorrect as it is one of the terms in the expression, not the final result.

Correct Answer: C

Rationale: To convert kilometers to miles, we can use the conversion factor of 1 kilometer is approximately 0.621 miles. Therefore, to find the distance in miles, we multiply 45 kilometers by 0.621, which equals approximately 28 miles. Choice C is correct because it correctly converts the distance from kilometers to miles. Choice A (42 miles), Choice B (37 miles), and Choice D (16 miles) are incorrect because they do not correctly convert kilometers to miles. Choice A overestimates the distance, Choice B underestimates it, and Choice D significantly underestimates it.
