What’s the work and answer for this? Someone please tell me

42, 39

Step-by-step explanation:

okay so the median means the middle. So how I used to do these is i would just cross off the first number and last number and then keep going through the middle.

10, 39, 71, 42, 39, 76, 38, 25

39, 71, 42, 39, 76, 38

71, 42, 39, 76

42, 39

But if there is two like in this case, if it's a complete middle number on equal sidess, then you just use both numbers.

answer: 140

step-by-step explanation:

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people

- "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."
