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.

Correct Answer: B

Rationale: To find the sale price of the sweater marked 15% off, you first calculate the discount amount by multiplying $78 by 15% (0.15), which equals $11.70. Then deduct this discount from the original price: $78 - $11.70 = $66. Therefore, choice B ($66) correctly estimates the sale price. Choice A ($12) is too low and does not consider the 15% discount. Choice C ($22) is also too low and does not account for the correct discount amount. Choice D ($69) is close but does not reflect the correct calculation after the 15% discount.

Correct Answer: A

Rationale: To find the length of the unknown leg, we can use the Pythagorean theorem: a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse of a right triangle. Given a = 9 feet and c = 19 feet, we can solve for b: 9^2 + b^2 = 19^2 81 + b^2 = 361 b^2 = 280 b ≈ √280 ≈ 16.7 feet Therefore, the correct answer is A (16.7 feet). Choice B (16.0 feet) is incorrect as it does not account for rounding to the nearest tenth. Choice C (17.4 feet) and choice D (8.4 feet) are incorrect as they do not match the calculated value.

Correct Answer: B

Rationale: To find the median, first, sort the data set in ascending order: -3, -2, 0, 5, 10. The middle value is the median, which is 0 in this case. This is the correct answer (B). The other choices are incorrect because: A: 10 is the highest value, not the middle value. C: 5 is not the middle value when the data set is arranged in ascending order. D: 2 is not present in the data set, making it an invalid choice.

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.
