Practice Math TEAS TEST

Correct Answer: B

Rationale: Failed to generate a rationale after 5 retries.

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.

Correct Answer: A

Rationale: The correct answer is A because a factor is a number that can be multiplied by another number to give the original number. For example, in the case of 6, factors would be 1, 2, 3, and 6. These numbers can be multiplied to get 6. Choice B is incorrect because it describes a divisor. Choice C is incorrect as it does not specifically define a factor but rather a relationship between two numbers. Choice D is incorrect as factors can be numbers less than, equal to, or greater than 1.

Correct Answer: B

Rationale: The correct answer is B: Find all pairs of numbers that multiply to give the number. To find factors, we need to identify pairs of numbers that, when multiplied together, result in the original number. This method ensures that we consider all possible combinations of factors. Dividing the number by all possible numbers (A) is not efficient and may lead to overlooking certain factors. Listing all the multiples of the number (C) is incorrect as it focuses on multiples rather than factors. Adding the digits of the number together (D) is unrelated to finding factors.

Correct Answer: A

Rationale: The correct way to display the frequency for each day of the week when students get up after 8 a.m. is through a histogram. Histograms are used to display the distribution of continuous data into intervals or bins, making them ideal for showing frequency distributions. In this case, each day of the week can be represented along the x-axis, with the frequency of students getting up after 8 a.m. on the y-axis. By using a histogram, we can easily visualize and compare the frequency of waking up late on different days. Summary: - Choice A (Histogram) is correct as it effectively displays frequency distributions. - Choice B (Pie chart) is not suitable for showing frequency distributions of days of the week. - Choice C (Bar graph) could work but histograms are more specifically designed for this purpose. - Choice D (Scatter plot) is used to show relationships between two continuous variables, not frequency distributions.
