Question 3

Karen is constructing a pie graph to represent the number of hours her classmates do homework each day. She found that 8/24 did homework for three hours each day.In her pie graph, this would represent how
Many degrees?

Accepted Answer

To find the number of degrees for each category in a pie graph, you need to find the fraction of the total that it represents and multiply by 360 (which is the total number of degrees in a circle). So, 8/24 simplifies to 1/3. 1/3 multiplied by 360 is 120 degrees. Therefore, the answer is choice C, 120°. In order to find the number of degrees that 8/24 represents in a pie graph, we need to multiply it by the total number of degrees in a circle (360°). 
8/24 * 360° = 120° 
Therefore, choice C is the correct answer. The other choices are not the correct calculation for this problem.

Question 6

In the figure below, what class boundary has 30% of the data?

Accepted Answer

In order to find the class boundary with 30% of the data, we need to add up the frequencies cumulatively starting from the lowest class boundary until we reach 30% of the total data. From the cumulative frequency column, we can see that the total frequency is 50 (the sum of all the frequencies). 30% of 50 is 15, so we need to find the class boundary that is associated with a cumulative frequency of 15. Looking at the cumulative frequency column, we can see that the class boundary of 40.5-60.5 has a cumulative frequency of 16, which is greater than 15. Thus, the previous class boundary, which is 20.5-40.5, must be the one with 30% of the data. Therefore, the answer is C.

Question 8

Choose the correct statement describing the following stem and leaf plot for grades on a linear algebra exam.

Accepted Answer

The stem and leaf plot shows that there were 29 students who took the exam and that nine of them scored between 80 and 89. The range of the grades is not provided, and there are gaps in the data as there are missing stems and leaves. The plot does not show evidence of bimodal data. The stem and leaf plot shows the number of students who scored within each ten-point range. There are 29 students represented on this plot. Therefore, there is no information regarding the range of grades. However, it is clear that 9 students scored between 80 and 89, so option B is correct. There also appears to be no gaps in the data, but there is not enough information to determine if the data is bimodal.

Question 13

For the table below, calculate the percent of students that fell within the B class.

Accepted Answer

To calculate the percentage of students that fell within the B class, you need to divide the number of students in the B class by the total number of students and then multiply by 100 to get the percentage. So, (7+5)/28 * 100 = 25%. Therefore, the correct choice is B.
