Drake made 14 out of 20 free throw shots. About how many out of the next 30 free
throw shots would you expect him to make?

Work Shown:

14/20 = 70/100 after multiply top and bottom by 5

70/100 = 70%

Drake makes 70% of his free throws

If he attempts 30 of them, then he should make about 0.70*30 = 21

Alternative Method:

(amount made)/(amount attempted) = (amount made)/(amount attempted)

14/20 = x/30

14*30 = 20*x ... cross multiply

420 = 20x

20x = 420

x = 420/20

x = 21

This is another way to see that we expect Drake to make about 21 free throws.

your answer would be b

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."
