Math Practice TEAS Test

Correct Answer: C

Rationale: The correct answer is C: 8 pints. There are 8 pints in a gallon because 1 gallon is equivalent to 8 pints. This conversion is based on the fact that a gallon is defined as 128 fluid ounces and a pint is 16 fluid ounces, so 128/16 = 8 pints in a gallon. Choice A (2 pints) is incorrect because it does not correspond to the correct conversion. Choice B (4 pints) is incorrect as it is half of the correct answer. Choice D (16 pints) is incorrect as it represents the total number of fluid ounces in a gallon, not the number of pints.

Correct Answer: B

Rationale: To calculate a 30% decrease, you multiply the current dosage (340 mg) by 0.30 to find the decrease amount: 340 mg x 0.30 = 102 mg. Subtract the decrease from the current dosage to get the new dosage: 340 mg - 102 mg = 238 mg (Option B). Option A (70 mg) is incorrect as it represents a 79% decrease. Option C (270 mg) is incorrect as it does not account for the 30% decrease. Option D (340 mg) is incorrect as it does not reflect the required decrease.

Correct Answer: A

Rationale: The correct answer is A: Mile is bigger; 1 mile is 1.609 km. This is because a mile is a longer unit of measurement compared to a kilometer. The conversion factor is 1 mile equals 1.609 kilometers. To convert miles to kilometers, you multiply the number of miles by 1.609. The other choices are incorrect because: B: Kilometer is bigger; 1 km is 1.609 miles - This is incorrect as a kilometer is shorter than a mile. C: Mile is bigger; 1 mile is 1.5 km - This is incorrect as 1 mile is actually equal to about 1.609 kilometers. D: Kilometer is bigger; 1 km is 2 miles - This is incorrect as a kilometer is shorter than 2 miles.

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.
