Practice Math TEAS TEST

Correct Answer: C

Rationale: The data set has two distinct peaks at values 2 and 8, making it bimodal. This is evident as there are two modes in the data set. The frequencies of 2 and 8 are higher compared to the other values, creating the bimodal distribution. Choices A, B, and D are incorrect. A uniform distribution would have equal frequencies for all values, which is not the case here. Right-skewed distribution would have a long tail on the right side, which is also not observed. Left-skewed distribution would have a long tail on the left side, which is not the case here.

Correct Answer: A

Rationale: The correct answer is A: 2W + 2(W + 3). To find the perimeter of a rectangle, you add up all its sides. Given that the length is 3 units greater than the width, the length is represented as W + 3. So, the expression for the perimeter is 2W (for the width) + 2(W + 3) (for the length). This simplifies to 2W + 2W + 6, which further simplifies to 4W + 6, representing the correct perimeter expression. Summary: B: W + W + 3 is incorrect as it only adds the width twice and does not account for the length. C: W(W + 3) is incorrect as it represents the area of the rectangle, not the perimeter. D: 2W + 2(3W) is incorrect as it incorrectly combines the width and length terms in the expression.

Correct Answer: A

Rationale: The correct answer is A: A shared multiple of two denominators. In order to add or subtract fractions, they must have a common denominator. This means they need to have the same bottom number. By finding the least common multiple of the denominators, you ensure that the fractions have the same base for accurate calculations. Choice B is incorrect because the common denominator is related to the denominators, not the numerators. Choice C is incorrect as the common denominator specifically refers to the bottom number in fractions. Choice D is incorrect as a common denominator may not necessarily divide evenly into both fractions, but it must be a multiple of both denominators.

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.
