TEAS 7 Math Practice Test

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: A

Rationale: The correct answer is A: $90. Given the ratio of 1:3 for house savings to rent, and the rent of $270 per month, we can set up a proportion. Let x be the amount saved for the house. The ratio equation is: x/270 = 1/3. Cross-multiplying gives x = 270/3 = $90. Therefore, the roommate saves $90 each month. Choice B: $270 is incorrect because that is the amount of rent paid, not the amount saved for the house. Choice C: $730 is incorrect as it is not derived from the given ratio and rent amount. Choice D: $810 is incorrect as it is also not in line with the ratio and rent information provided.

Correct Answer: D

Rationale: The product of two even integers and one odd integer will always be an even integer. This is because multiplying any number of even integers together results in an even number, and multiplying any number of odd integers together also results in an odd number. Therefore, the product could not be 3.75 (odd), 9 (odd), or 16.2 (even non-integer). The only possible option is 24, as it is an even integer and can be obtained by multiplying two even integers and one odd integer together.

Correct Answer: C

Rationale: To determine the correct dosage, multiply the patient's weight (60 kg) by the prescribed dosage (5 mg/kg): 60 kg x 5 mg/kg = 300 mg. Choice C is correct. Choices A, B, and D are incorrect as they do not result from the correct calculation. Choice A (100 mg) is too low, Choice B (150 mg) is also too low, and Choice D (400 mg) is too high based on the calculation.

Correct Answer: B
