Practice Math TEAS TEST

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Given equation: D = 2R 2. To find the relationship between D and R, we see that D is equal to 2 times R. 3. Thus, D is twice as much as R, making choice A the correct answer. 4. Other choices are incorrect: - B: R is twice as much as D (incorrect as the equation shows D is twice R). - C: R is two times D (incorrect as the equation states D is two times R). - D: D is two more than R (incorrect as D is actually two times R).

Correct Answer: B

Rationale: The correct answer is B: Find all pairs of numbers that multiply to give the number. To find factors, we need to identify pairs of numbers that, when multiplied together, result in the original number. This method ensures that we consider all possible combinations of factors. Dividing the number by all possible numbers (A) is not efficient and may lead to overlooking certain factors. Listing all the multiples of the number (C) is incorrect as it focuses on multiples rather than factors. Adding the digits of the number together (D) is unrelated to finding factors.

Correct Answer: A

Rationale: To find the length of the unknown leg, we can use the Pythagorean theorem: a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse of a right triangle. Given a = 9 feet and c = 19 feet, we can solve for b: 9^2 + b^2 = 19^2 81 + b^2 = 361 b^2 = 280 b ≈ √280 ≈ 16.7 feet Therefore, the correct answer is A (16.7 feet). Choice B (16.0 feet) is incorrect as it does not account for rounding to the nearest tenth. Choice C (17.4 feet) and choice D (8.4 feet) are incorrect as they do not match the calculated value.

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: One. Any number raised to the power of zero equals one. This is because the rule for exponents states that any number raised to the power of zero is equal to one, regardless of the base number. This rule is derived from the properties of exponents and is a fundamental concept in mathematics. Choices B, C, and D are incorrect because raising a number to the power of zero does not result in the number itself, zero, or two. The key to remember is that any number raised to the power of zero is always equal to one, making choice A the correct answer.
