Practice Math TEAS TEST

Correct Answer: A

Rationale: Correct Answer: A Rationale: To convert Fahrenheit to Celsius, you first subtract 32 from the Fahrenheit temperature and then divide by 1.8. This is because the conversion formula is (F - 32) / 1.8. To convert Celsius to Fahrenheit, you multiply the Celsius temperature by 1.8 and then add 32. The formula for this conversion is (C * 1.8) + 32. Therefore, choice A is correct as it follows the correct conversion formulas for both Fahrenheit to Celsius and Celsius to Fahrenheit. Summary of other choices: B: Incorrect because dividing by 2 in Fahrenheit to Celsius conversion is incorrect. C: Incorrect because multiplying by 2 in Fahrenheit to Celsius conversion is incorrect. D: Incorrect because subtracting 30 in Fahrenheit to Celsius conversion is incorrect.

Correct Answer: B

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 convert yards to feet, you multiply by 3 since 1 yard = 3 feet. Therefore, 9 yards x 3 feet/yard = 27 feet. Option D is correct. Option A is incorrect as it miscalculates the conversion. Option B and C are also incorrect due to incorrect conversion.

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.
