TEAS 7 Math Practice Test

Correct Answer: B

Rationale: To calculate a 20% decrease from 400 mg, we first find 20% of 400, which is 80 mg. Subtracting 80 mg from the current dosage of 400 mg gives us the new dosage after the decrease: 400 mg - 80 mg = 320 mg. Therefore, the correct answer is B (80 mg). Choices A, C, and D are incorrect as they do not accurately reflect a 20% decrease from the original 400 mg dosage.

Correct Answer: B

Rationale: To find the approximate number of people who voted for the proposition, we multiply the town's population by the percentage that voted: 51,623 * 9.5% = 51,623 * 0.095 = 4,904. Therefore, approximately 5,000 people voted for the proposition. Choice A (3,000) is too low because 9.5% of the population would result in more voters. Choice C (7,000) is too high because it exceeds the calculation based on the given percentage. Choice D (10,000) is also too high as it overestimates the number of voters based on the percentage provided.

Correct Answer: B

Rationale: The correct answer is B (25). To find the range, subtract the smallest value from the largest value in a set of data. Given the options, 32 (largest) minus 7 (smallest) equals 25. Therefore, the range in the number of flights the flight attendant made is 25. Option A (20) is incorrect as it is smaller than the actual range. Option C (29) and D (32) are incorrect because they are larger than the actual range, making them invalid choices.

Correct Answer: C

Rationale: The correct answer is C because it asks for the greatest percentage of a specific group among the staff at Hospital X and Hospital Y. This is a broader group compared to the other choices, making it more likely to have a higher percentage. Choices A, B, and D are specific to Hospital X or Y only, limiting the pool of individuals being considered and reducing the likelihood of having the highest percentage. Choice C considers the combined staff of two hospitals, increasing the pool of individuals and making it more probable to have a higher percentage of doctors among the staff.

Correct Answer: C

Rationale: Rationale: To find a reasonable estimate, divide the total distance by the number of days. 1480 miles / 5 days = 296 miles/day. The closest option is 300 miles/day (Choice C). This is the correct answer as it is the most accurate estimate of the daily distance. Choices A, B, and D are incorrect as they are either too low or too high compared to the calculated estimate, making them unreasonable choices.
