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: A

Rationale: To correctly order the numbers from least to greatest, we start by comparing the negative numbers first. The most negative number is -271.906, followed by -193.823. Then, we move on to the positive numbers, starting with 145.884 and ending with 235.971. Therefore, the correct order is -271.906, -193.823, 145.884, 235.971 (Option A). Choice B is incorrect because it incorrectly places 235.971 before -193.823. Choice C is incorrect as it places 145.884 before -193.823. Choice D is incorrect because it swaps the positions of -193.823 and -271.906.

Correct Answer: A

Rationale: The correct answer is A: Eritrea. To determine the largest increase in healthcare spending per capita from 2013 to 2015, we need to calculate the difference between the spending in 2015 and 2013 for each country. By comparing the dollar amount increase for each country, it is evident that Eritrea experienced the largest increase. This is because the dollar amount increase for Eritrea is greater than that of the other countries listed. Sudan, Tanzania, and Kenya had smaller increases in dollars spent per capita during the same period. Therefore, A is the correct answer.

Correct Answer: D

Rationale: To find the correct answer, we first calculate how much of the burger was left after one friend ate a quarter (3/4 left). Then, the other two friends divide this among themselves equally, so each receives half of the remaining portion (3/4 * 1/2 = 3/8). Therefore, each of the other two friends received 3/8 of the burger, which is represented by choice D (8-Mar). Choices A, B, and C are incorrect because they do not accurately reflect the correct calculation of dividing the remaining portion equally between the two friends.
