TEAS Test Math Prep Questions

Question 1 of 5

At the beginning of the day, Xavier has 20 apples. At lunch, he meets his sister Emma and gives her half of his apples. After lunch, he stops by his neighbor Jim's house and gives him 6 of his apples. He then uses � of his remaining apples to make an apple pie for dessert at dinner. At the end of the day, how many apples does Xavier have left?

Correct Answer: D

Rationale: Failed to generate a rationale after 5 retries.

Question 2 of 5

The value of 6 x 12 is the same as:

Correct Answer: A

Rationale: The correct answer is A: 2 x 4 x 4 x 2. To find the value of 6 x 12, we can break it down into simpler multiplication. 6 x 12 = 6 x (4 x 3) = (2 x 3) x (4 x 3) = 2 x 4 x 4 x 2. This shows that the value of 6 x 12 is indeed equal to 2 x 4 x 4 x 2. Explanation for why other choices are incorrect: B: 7 x 4 x 3 does not equal 6 x 12. C: 6 x 6 x 3 equals 108, not 72 (6 x 12). D: 3 x 3 x 4 x 2 equals 72, but the order of multiplication is not the same as in 6 x 12, making it incorrect.

Question 3 of 5

Which measure for the center of a small sample set would be most affected by outliers?

Correct Answer: A

Rationale: The correct answer is A: Mean. The mean is calculated by summing all values and dividing by the number of values. Outliers can significantly skew the mean because they have a greater impact on the total sum. The median (B) is less affected by outliers since it is the middle value when data is sorted. The mode (C) is the most frequent value and is not affected by outliers. Choice D is incorrect as outliers can impact the mean in a small sample set.

Question 4 of 5

Solve this equation: 2x+8=0

Correct Answer: A

Rationale: To solve the equation 2x + 8 = 0, we first isolate x by subtracting 8 from both sides. This gives us 2x = -8. Then, divide by 2 on both sides to get x = -4 (Choice A). This is the correct answer because -4 satisfies the equation. Choices B, C, and D are incorrect as they do not yield a solution that makes the equation true when substituted back into it.

Question 5 of 5

Express the solution to the following problem in decimal form:

Correct Answer: C

Rationale: The correct answer is C: 0.84. To convert a percentage to a decimal, you divide by 100. In this case, 84% divided by 100 equals 0.84. Choice A is incorrect as 0.042 is not equivalent to 84%. Choice B is incorrect as 84% is not the same as 0.84. Choice D is incorrect as 0.42 is not the correct decimal form of 84%. Therefore, the correct representation of 84% in decimal form is 0.84.
