Math Practice TEAS Test

Correct Answer: B

Rationale: The correct answer is B (0.151). To calculate the percentage of total rainfall in October, you divide the amount of rainfall in October by the total rainfall in the timeframe. In this case, 0.151 is the correct percentage of rainfall in October. Choice A (0.135), C (0.169), and D (0.177) are incorrect as they do not accurately represent the percentage of rainfall in October when compared to the total rainfall.

Correct Answer: B

Rationale: To convert liters to quarts, we use the conversion factor 1 liter = 1.06 quarts. Therefore, 1 liter is equal to 1.06 quarts. The correct answer is B. Choice A is incorrect as it states 1 quart is equal to 1 liter. Choice C is incorrect as it states 2 quarts are in 1 liter. Choice D is incorrect as it states 0.5 quarts are in 1 liter.

Correct Answer: A

Rationale: The correct answer is A: 2.54 centimeters in an inch; 0.393 inches in a centimeter. The conversion factor between inches and centimeters is 2.54, derived from the definition of an inch. To convert inches to centimeters, you multiply by 2.54. Conversely, to convert centimeters to inches, you divide by 2.54. The other choices are incorrect because they do not reflect the accurate conversion factor between inches and centimeters. B and C have incorrect conversion ratios, while D has an incorrect relationship between inches and centimeters.

Correct Answer: B

Rationale: To solve the equation, we follow the order of operations: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Step 1: 5 + 3 = 8 Step 2: 4 - 6 = -2 Step 3: -2 / 2 = -1 Step 4: 8 - 1 = 7 Therefore, the correct answer is 7 (Option D). Option A is incorrect as it does not consider all operations. Option C is incorrect as it does not correctly follow the order of operations. Option D is incorrect as it does not correctly calculate the result.

Correct Answer: A

Rationale: The correct answer is A: Ranges. Histograms display continuous data in intervals or ranges, showing the frequency of data points within each range. This is a key feature that distinguishes histograms from bar graphs, which depict discrete categories. Ranges are crucial in histograms to visualize the distribution of data across different intervals, allowing for a better understanding of the data's spread and frequency distribution. Choices B, C, and D are incorrect as bar graphs also utilize categories, labels, and percentages in their presentation of data, respectively.
