A basketball player who has made 70% of his foul shots during the season gets to take 5 shots in the first playoff game. What's the expected number of shots he should make? And what's the standard deviation?

1:8

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z > the scale factor

VA ---> volume of the sphere A

VB ---> volume of the sphere B

so

we have

substitute

That means> The volume of the sphere B is 8 times the volume of the sphere A

therefore

The ratio of the volume of sphere A to sphere B is
