ATI TEAS Math Practice Test

Correct Answer: B

Rationale: To calculate the percentage more female staff at Hospital Y than X, we first find the difference in the percentage of female staff between the two hospitals. Let's say Hospital X has 40% female staff and Hospital Y has 50%. The difference is 50% - 40% = 10%. This means that Hospital Y has 10% more female staff than Hospital X. Therefore, the correct answer is B (10%). Option A (5%) is incorrect because the actual percentage more is 10%. Option C (15%) and D (20%) are incorrect as they overestimate the difference in female staff percentages between the two hospitals.

Correct Answer: A

Rationale: The correct answer is A: 1/2. When flipping a fair coin, there are only two possible outcomes - heads or tails. Since each outcome is equally likely, the probability of getting heads is 1 out of 2, or 1/2. Choice B (1/3), C (1/4), and D (1/5) are incorrect because they do not accurately reflect the equally likely outcomes of a coin flip. The probability of getting heads is always 1/2 when flipping a fair coin.

Correct Answer: A

Rationale: The correct answer is A: y = 15 + 28x. This equation represents the total amount of money Andy will have saved. Initially, he has $15 saved (y = 15 when x = 0). Then, he saves $28 per month, which is represented by 28x. Therefore, the total amount saved is the initial $15 plus the monthly savings of $28 times the number of months x. Summary: - Choice A is correct because it includes the initial savings of $15 and the monthly savings of $28x. - Choice B is incorrect because it incorrectly adds $15 to the monthly savings. - Choice C is incorrect because it only represents the monthly savings without considering the initial amount saved. - Choice D is incorrect because it adds the monthly savings before the initial amount saved.

Correct Answer: D

Rationale: The correct answer is D (6.97 hours). To calculate the total time taken, first find the time for the first segment: 305 miles / 65 mph = 4.69 hours. Then add the 15-minute stop in hours: 15 minutes / 60 = 0.25 hours. Next, find the time for the second segment: 162 miles / 80 mph = 2.025 hours. Add up these times: 4.69 hours + 0.25 hours + 2.025 hours = 6.965 hours, which rounds to 6.97 hours. Choice A is incorrect as it does not account for the distance covered and the stop. Choices B and C are incorrect as they do not consider the time for the second segment.

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.
