The longest spin of a basketball on one finger 255 minutes. about how many hours is that

two data sets with the same median will not have the same varaibility

step-by-step explanation:

- "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."

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

60: 45 =12: 9 =4: 3 so the answer is 4: 3
