Math Practice TEAS Test

Correct Answer: A

Rationale: To convert kilograms to pounds, we use the conversion factor 1 kg = 2.20462 lbs. So, to find Stella's weight in pounds, we multiply her weight in kilograms (56) by the conversion factor: 56 kg * 2.20462 lbs/kg ≈ 123.46 lbs. Therefore, Stella's approximate weight in pounds is 123 pounds. Choice B (110 pounds) is incorrect as it underestimates the conversion. Choice C (156 pounds) and D (137 pounds) overestimate the conversion.

Correct Answer: B

Rationale: The correct answer is B: 5,280 ft. There are 5,280 feet in a mile because a mile is defined as 5,280 feet. This standard measurement is widely accepted in the United States. The other choices (A, C, D) are incorrect because they do not correspond to the precise conversion factor for a mile. Choice A (1,000 ft) is too small, Choice C (2,000 ft) is also too small, and Choice D (10,000 ft) is too large. Therefore, B is the correct answer as it accurately reflects the established conversion of feet in a mile.

Correct Answer: B

Rationale: The correct answer is B: Group A is positively skewed, Group B is normal. In a double bar graph, skewness can be identified based on the distribution of bars. 1. Positive skewness means the tail of the distribution extends to the right, indicating a higher frequency of lower values. 2. Looking at Group A, if the bars are concentrated on the left side with a few bars extending to the right, it suggests positive skewness. 3. Group B being normal implies a symmetrical distribution with no skewness. Therefore, B is correct as it correctly describes the skewness of Group A and Group B based on the given information. Summary: A: Incorrect - Group A is positively skewed, not negatively skewed. C: Incorrect - Group B is normal, not neutral. D: Incorrect - Group A is positively skewed, not normal.

Correct Answer: D

Rationale: The correct answer is D: 4 quarts. There are 4 quarts in a gallon. This is because a gallon is a unit of volume equal to 128 fluid ounces, and each quart is equal to 32 fluid ounces. Therefore, to find out how many quarts are in a gallon, you divide the total number of fluid ounces in a gallon by the number of fluid ounces in a quart (128 ÷ 32 = 4). Choice A (1 quart) is incorrect because a quart is smaller than a gallon. Choice B (2 quarts) is incorrect as it is half of the correct amount. Choice C (3 quarts) is also incorrect as it is three-quarters of the correct amount. The correct answer is D (4 quarts) because it accurately represents the conversion of fluid ounces from gallons to quarts.
