Math Practice TEAS Test

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.

Correct Answer: A

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: C

Rationale: A rational number can be expressed as a fraction or a decimal. A fraction is a ratio of two integers, and a decimal can represent a rational number, such as 0.5 (which is 1/2). Hence, a rational number can be a fraction, decimal, or a whole number. Options A and D are incorrect because a rational number is not limited to being a whole number or cannot be a decimal. Option B is partially correct but doesn't cover the full scope of possibilities for rational numbers. Option C is the correct answer as it encompasses all the possible representations of a rational number.

Correct Answer: B

Rationale: To calculate the total trip duration, first find the time taken for the first leg (305 miles at 65 mph = 305/65 = 4.69 hours). Then factor in the 15-minute stop (0.25 hours). Finally, calculate the time for the second leg (162 miles at 80 mph = 162/80 = 2.03 hours). Add all times together (4.69 + 0.25 + 2.03 = 6.97 hours), which is closest to choice B (6.69 hours). This is the correct answer as it considers the time for each leg and the stop accurately. Other choices are incorrect because they do not accurately calculate the total trip duration.

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.
