Answer:

49% probability that Mitchell will be a goalie today

Step-by-step explanation:

If Coach White coaches, the probability of being goalie is 0.55.

Coach White has a 70% probability of coaching.

If Coach Jackson coaches, the probability of being goalie is 0.35.

Coach Jackson has a 100-70 = 30% probability of coaching.

What is the probability that Mitchell will be a goalie today?

This is 55% of 70% plus 35% of 30%

Then

P = 0.55*0.7 + 0.35*0.3 = 0.49

49% probability that Mitchell will be a goalie today

Using disks or washers, find the volume of the solid obtained by rotating the region bounded by the curves y=x−1 y=0 x=2 and x=5

Irina-Kira [14]

Using disks ...
$V= \pi \int\limits^5_2 {(x-1)^{2}} \, dx =\pi(\frac{1}{3}(5^{3}-2^{3})-(5^{2}-2^{2})+(5-2))=21\pi$

The volume is 21π units³ ≈ 65.97 units³
