TEAS Practice Math Test

1. What was the mean time for the women who ran the 200m event at the 2008 Olympic Games (times in seconds: 22.33, 22.50, 22.50, 22.61, 22.71, 22.72, 22.83, 23.22)?

Correct answer: C

Rationale: To find the mean time, you need to add all the times (22.33 + 22.50 + 22.50 + 22.61 + 22.71 + 22.72 + 22.83 + 23.22) and then divide by the total number of times (8). This calculation results in a mean time of 22.68 seconds. Choice A, 22.50 sec, is incorrect because it is the time of one of the runners, not the mean time. Choice B, 22.66 sec, and Choice D, 22.77 sec, are also incorrect as they are not the calculated mean of the given times.

2. Which of the following evidence from the passage supports the inference that providing nap rooms at work can improve employee productivity?

Correct answer: B

Rationale: The correct answer is B because the evidence from the 2008 study mentioned in the passage supports the inference that napping for 60 minutes can improve verbal memory, motor skills, and perceptual learning better than caffeine. This indicates that providing nap rooms at work can lead to improved productivity by enhancing cognitive functions. Choice A talks about the fatigue reported by employees but does not directly link it to productivity improvement. Choice C mentions that many successful companies have adopted the practice of work naps but does not specifically tie it to productivity enhancement. Choice D states the intention to provide nap rooms for employees but does not provide direct evidence of productivity improvement.

3. The doctor carefully examined the patient. Which word is the comparative form of the adjective 'careful'?

Correct answer: C

Rationale: The comparative form of the adjective 'careful' is 'more careful' when comparing two things. In this context, it is comparing the level of care in examining the patient, indicating a higher degree of care than just 'careful.' Choice A, 'careful,' is the positive form of the adjective and not comparative. Choice B, 'carelessly,' is an adverb that conveys the opposite meaning. Choice D, 'most careful,' is the superlative form of the adjective, indicating the highest degree of care, not the comparative form.

4. Which of the following sentences is grammatically correct?

Correct answer: C

Rationale: The correct structure is 'whom to hold responsible' as 'whom' is the object of the verb 'to hold.' In choice A, 'who' should be 'whom' to indicate the object of the verb. Choice B is incorrect as 'whom' is incorrectly placed before 'was responsible.' Choice D is also incorrect due to the awkward phrasing and the use of 'on' which is unnecessary.

5. In the town of Ellsford, there are approximately 1,450 residents who attend church weekly. If around 400 of them attend Catholic Churches, what percentage of churchgoers in Ellsford attends Catholic Churches?

Correct answer: B

Rationale: To find the percentage of churchgoers who attend Catholic Churches, divide the number of Catholic churchgoers by the total number of churchgoers and then multiply by 100. (400 ÷ 1,450) × 100 ≈ 27.59%, which rounds to 28%.
