Students in 7th grade took a standardized math test that they also had taken in 5th grade. the results are shown on the dot plot, with the most recent data shown first. which statement is true? both data sets have a gap. both data sets have the same median. both plots have the same mode. both data sets have the same number of data points.

both sets have the same number of points

It is d.

Step-by-step explanation:

They have different medians and modes.  The 7th grade results , as you would expect, show better results than the 5th grade data.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
