Homemade applesauce is one of Jared's favorite foods, so he stocked up on 10 pounds of
Vanyuwa [196]

Answer:

<h2>5 quarts</h2>

Step-by-step explanation:

Let's think through this bit by bit.

<em>10 lbs * 16 oz/lb = 160 oz. of apples.</em>

In the proportion below, we can see we simply divide by 8, in terms of magnitude.

8 oz -> 1 cup

160 oz -> 160/8 -> 20 cup

20 cups! Is it the answer? NO! They're asking for it in units of <em>quarts, not cups.</em>

We must remember that 1 quart = 4 cups.

20 cups * 1/4 qt/cups = 5 quarts

A basketball player has made 6060​% of his foul shots during the season. Assume the shots are independent. ​
motikmotik

Answer:

a) 2.5 shots

b) 59.4 shots

c) 4.87 shots

Step-by-step explanation:

Probability of making the shot = 0.6

Probability of missing the shot = 0.4

a) The expected number of shots until the player misses is given by:

E(X) = \frac{1}{P(X)}=\frac{1}{0.4}  \\E(X) = 2.5\ shots

The expected number of shots until the first miss is 2.5

b) The expected number of shots made in 99 attempts is:

E=99*0.6\\E=59.4\ shots

He is expected to make 59.4 shots

c) Let "p" be the proportion shots that the player make, the standard deviation for n = 99 shots is:

s=\sqrt{n*p*(1-p)}\\ s= 4.87\ shots

The standard deviation is 4.87 shots.

What is 1/x^2 in the power of x
Serhud [2]

we have given that \frac{1}{x^2}.

we need to express this interms of power of x .

we know that \frac{1}{x^n} =x^-n.

in place of n we have 2 .so \frac{1}{x^2} =x^-2.

so this will be the expression interms of power of x .
