Practice Math TEAS TEST

Correct Answer: A

Rationale: The correct answer is A because a prime number is defined as a number that is divisible by only 1 and itself. This means prime numbers have exactly two factors, 1 and the number itself, making them indivisible by any other number. Choice B is incorrect because prime numbers are not divisible by any other numbers except 1 and themselves. Choice C is incorrect because prime numbers are not divisible by any number, only by 1 and themselves. Choice D is incorrect because prime numbers actually have exactly two factors, not three.

Correct Answer: D

Rationale: To find the portion each of the other three friends received, we first calculate what fraction of the pizza was left after one friend ate half. Half of the pizza is 1/2, so 1 - 1/2 = 1/2 is left. Then, we divide 1/2 equally among the three friends, giving each 1/2 ÷ 3 = 1/6. Therefore, each of the other three friends received 1/6 of the pizza. Summary: A: 1/5 - Incorrect. Not the correct division after one friend ate half. B: 1/3 - Incorrect. The correct division is not one-third after one friend ate half. C: 1/4 - Incorrect. The correct division is not one-fourth after one friend ate half.

Correct Answer: C

Rationale: The correct answer is C: Bell-shaped. This is because a symmetric distribution with a single peak is characteristic of a bell-shaped distribution, also known as a normal distribution. In a bell-shaped distribution, the data is evenly distributed around the mean, creating a symmetrical pattern. Choice A (Uniform) is incorrect because a uniform distribution would show an equal frequency of weights across all values, without a distinct peak. Choice B (Bimodal) is incorrect because a bimodal distribution would have two distinct peaks, indicating two separate groups of weights rather than a single peak. Choice D (Skewed right) is incorrect because a right-skewed distribution would have a tail extending to the right, with the majority of weights concentrated on the left side, not centered around a single peak.

Correct Answer: B

Rationale: To calculate the percentage increase, subtract the initial value from the final value, then divide by the initial value and multiply by 100. Percentage Increase = [(1072-841)/841] x 100 ≈ 27% Therefore, choice B (27%) is the correct answer as it represents the approximate percentage increase in client volume. Choice A (22%) is incorrect because it does not accurately reflect the calculated percentage increase. Choice C (127%) is incorrect as it is way too high and does not align with the actual increase. Choice D (78%) is incorrect as it is also significantly off from the calculated percentage increase.

Correct Answer: A

Rationale: The correct answer is A because a factor is a number that can be multiplied by another number to give the original number. For example, in the case of 6, factors would be 1, 2, 3, and 6. These numbers can be multiplied to get 6. Choice B is incorrect because it describes a divisor. Choice C is incorrect as it does not specifically define a factor but rather a relationship between two numbers. Choice D is incorrect as factors can be numbers less than, equal to, or greater than 1.
