Using the binomial distribution, the mean number of balls you would expect him to catch is of 7.2.
<h3>What is the binomial probability distribution?</h3>
It is the probability of exactly <u>x successes on n repeated trials, with p probability</u> of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
For this problem, the parameters are:
n = 8, p = 0.9.
Hence the mean is:
E(X) = np = 8 x 0.9 = 7.2.

Answer:
No, because 4 is repeated in the domain.
Step-by-step explanation:
Because 34.4567 is closer to 34.46 than to 34.45, so the answer is 34.46.
Answer:
a. 26 inches by 31.2 inches
Step-by-step explanation:
The lengths(X) of the rectangular is 1.2 times longer than the width (Y), so you can put it into this equation
x= y * 1.2
x= 1.2 y
The area of the window is 811.2 square inches, so you can put this equation
x * y= 811.2
Combining both equations, you can get
x * y= 811.2
(1.2y) * y = 811.2
1.2y^2= 811.2
y^2= 676
y= 26
x= 1.2 y
x= 1.2(26)= 31.2
