Cindy is a first-year math teacher who has just collected a chapter test from her 4th period students. As Cindy reviews the test scores, she notices that while she has several students who have earned an A, most of the test scores are in the C to B range. She also notices that two of the scores are much lower than the rest, each earning an F. This makes sense to her, as those two students were absent for much of the chapter. However, she must now report to her principal on the performance of her class on this test. Which measure of central tendency should Cindy use in her report to the principal, if she wants to portray her students in the most favorable manner? A.
Cindy should use the mean of the test scores to produce the most positive report.
B.
Cindy should use the median of the test scores to produce the most positive report.
C.
Cindy should use the mode of the test scores to produce the most positive report.
D.
Cindy should use either the mean or the median, as these will produce the same value.

Atrain traveled for 1.5 hours to the first station, stopped for 30 minutes, then traveled for 4 hours to the final station where it stopped for 1 hour. the total distance traveled is a function of time. which graph most accurately represents this scenario? a graph is shown with the x-axis labeled time (in hours) and the y-axis labeled total distance (in miles). the line begins at the origin and moves upward for 1.5 hours. the line then continues upward at a slow rate until 2 hours. from 2 to 6 hours, the line continues quickly upward. from 6 to 7 hours, it moves downward until it touches the x-axis a graph is shown with the axis labeled time (in hours) and the y axis labeled total distance (in miles). a line is shown beginning at the origin. the line moves upward until 1.5 hours, then is a horizontal line until 2 hours. the line moves quickly upward again until 6 hours, and then is horizontal until 7 hours a graph is shown with the axis labeled time (in hours) and the y-axis labeled total distance (in miles). the line begins at the y-axis where y equals 125. it is horizontal until 1.5 hours, then moves downward until 2 hours where it touches the x-axis. the line moves upward until 6 hours and then moves downward until 7 hours where it touches the x-axis a graph is shown with the axis labeled time (in hours) and the y-axis labeled total distance (in miles). the line begins at y equals 125 and is horizontal for 1.5 hours. the line moves downward until 2 hours, then back up until 5.5 hours. the line is horizontal from 5.5 to 7 hours
