TEAS Math Practice Test Questions

Question 1 of 5

Which of the following equations does not represent a function?

Correct Answer: C

Rationale: The correct answer is C: x = y^2. This equation does not represent a function because it fails the vertical line test, where any vertical line intersects the graph at more than one point. In this case, for each x value, there are two corresponding y values (positive and negative square roots), violating the definition of a function where each input can only have one unique output. Choices A, B, and D all represent functions as each x value corresponds to only one y value, satisfying the function criteria.

Question 2 of 5

Express 3 5/7 as an improper fraction.

Correct Answer: A

Rationale: To convert 3 5/7 to an improper fraction, multiply the whole number (3) by the denominator (7) and add the numerator (5) to get 26. The denominator remains the same, resulting in 26/7. This is the correct answer because it represents the mixed number 3 5/7 in fraction form. Choice B (21/7) simplifies to 3, which is the whole number part of the mixed number. Choice C (22/7) is equivalent to the approximation of π and not the correct conversion of 3 5/7. Choice D (26/5) is incorrect as it does not represent the mixed number 3 5/7 accurately.

Question 3 of 5

How will 0.80 be written as a percent?

Correct Answer: D

Rationale: To convert a decimal to a percentage, you multiply by 100. Therefore, 0.80 * 100 = 80%. So, the correct answer is D. Choice A (40%) is incorrect because 0.80 is not equal to 0.40. Choice B (125%) is incorrect as 0.80 is less than 1. Choice C (90%) is incorrect as 0.80 is not equal to 0.90.

Question 4 of 5

4.67 miles is equivalent to how many kilometers to three significant digits?

Correct Answer: B

Rationale: To convert miles to kilometers, we use the conversion factor: 1 mile = 1.60934 kilometers. Therefore, 4.67 miles is equal to 4.67 * 1.60934 = 7.504 km. Rounding to three significant digits gives us 7.51 km, which is the correct answer (B). Choice A (7.514 km) is incorrect as it has been rounded to four significant digits. Choice C (2.90 km) and choice D (2.902 km) are incorrect as they are much smaller values due to incorrect calculations or rounding.

Question 5 of 5

A scientist is trying to determine how much poison will kill a rat the fastest. Which of the following statements is an example of an appropriate hypothesis?

Correct Answer: C

Rationale: The correct answer is C because it presents a clear and testable hypothesis that directly links the amount of poison given to the speed of rat death. It follows the format of an appropriate hypothesis by stating a cause-and-effect relationship that can be tested through experimentation. A is incorrect because it lacks a specific hypothesis and does not propose a clear relationship between the amount of poison and rat death. B is incorrect as it poses a question rather than a hypothesis, and it does not establish a direct connection between the variables. D is incorrect because it is a general statement about poison and rats without proposing a specific hypothesis to test.
