TEAS Test Math Questions

Correct Answer: C

Rationale: To find the mean, sum all values and divide by the total count. For this data set, sum = 16+18+17+15+19+14+12+11+10+16+18+17 = 183. Total count = 12. Mean = 183/12 = 15.25, which makes choice C, 16, the correct answer. Choice A, 14.25, and B, 15.25, are incorrect as they do not match the calculated mean. Choice D, 17, is incorrect as it is higher than the calculated mean value.

Correct Answer: A

Rationale: To multiply fractions, you simply multiply the numerators and denominators separately. So, (3/5) * (5/8) = (3*5)/(5*8) = 15/40. However, it can be simplified to 3/8 by dividing both numerator and denominator by 5. Thus, the correct answer is A: 3/8. Choice B (3/5) is the first fraction, not the result. Choice C (15/40) is the intermediate result before simplification. Choice D (3/30) is incorrect as the numerator should be 15, not 3.

Correct Answer: C

Rationale: To solve for x, first add 5 to both sides to isolate the variable: 3x = 21. Next, divide by 3: x = 7. Therefore, the correct answer is C (8). Choice A (7) is incorrect as the correct answer is 8. Choices B (5) and D (9) are incorrect as they are not solutions to the equation.

Correct Answer: D

Rationale: To find the rate of change in height per month, we multiply the daily growth rate by the number of days in a month. 4.2 inches/day * 30 days = 126 inches/month. Therefore, the correct answer is D. Choice A is incorrect as it is the daily growth rate, not the monthly rate. Choice B is incorrect as it is the same as the daily growth rate, not the monthly rate. Choice C is incorrect as it is not the result of the correct calculation.

Correct Answer: A

Rationale: To solve the inequality x > 5, we want to find all values of x that are greater than 5. This means x can be any number larger than 5 but not equal to 5. So, the correct answer is A. Choices B, C, and D are incorrect because they represent x being less than, greater than or equal to, and less than or equal to 5, respectively, which do not satisfy the original inequality x > 5.
