The distance vs. time graph of a car moving at constant speed should be a straight line. why do the data points in the graph plotted from observing the motion not fall right on the line? a. the distance is not exactly proportional to time even if the speed is exactly constant. b. the distance and time are proportional only if the correct units of meters an seconds are used. c. data points can never look like they fall right on a straight line. d. the measurements are inexact.

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.
