TEAS Math Practice Test Questions
Question 1 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.
Question 2 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?

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.
Question 3 of 5
A closet is filled with red, blue, and green shirts. If 1/4 of the shirts are green and 1/3 are red, what fraction of the shirts are blue?
Correct Answer: C
Rationale: To find the fraction of blue shirts, we need to subtract the fractions of green and red shirts from 1 (total). Given that 1/4 are green and 1/3 are red, the fraction of blue shirts is 1 - 1/4 - 1/3 = 12/12 - 3/12 - 4/12 = 5/12. Therefore, the correct answer is C: 5/12. Choice A (1/2) is incorrect as it doesn't consider the given fractions of green and red shirts. Choice B (1/3) is incorrect as it only considers the fraction of red shirts. Choice D (1/4) is incorrect as it only considers the fraction of green shirts.
Question 4 of 5
When rounding 245.2678 to the nearest thousandth, which place value would be used to decide whether to round up or round down?
Correct Answer: A
Rationale: To round 245.2678 to the nearest thousandth, we look at the digit in the thousandths place, which is 7. Since 7 is greater than or equal to 5, we round up. The ten-thousandths place, denoted by the digit 8 in this case, is used to decide whether to round up or down when rounding to the nearest thousandth. The correct answer is A (Ten-thousandths). Summary: A: Ten-thousandths - Correct, used to decide rounding up or down in rounding to the nearest thousandth. B: Thousandths - Incorrect, this is the place being rounded to. C: Hundredths - Incorrect, not relevant for rounding to the nearest thousandth. D: Thousand - Incorrect, not relevant for rounding to the nearest thousandth.
Question 5 of 5
What is the simplified form of the expression (x^2 + 2x)/(x)?
Correct Answer: A
Rationale: To simplify (x^2 + 2x)/(x), we first factor out x from the numerator to get x(x + 2). This simplifies to x + 2 since x/x = 1. Therefore, the correct answer is A: x + 2. Choice B is incorrect because it represents the original expression without simplification. Choice C is incorrect as it is the factored form of the original expression. Choice D is incorrect as it does not simplify to the correct form.
