Using the binomial distribution, it is found that the mean and the standard deviation of variable x are given as follows:
<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
The standard deviation of the binomial distribution is:
In this problem, we have that the parameters are given as follows:
n = 4, p = 0.75.
Hence the mean and the standard deviation are given as follows:
- E(X) = np = 4 x 0.75 = 3.

Answer:
(-3-8)/(-4+4)= -11/0= no slope and undefined
Step-by-step explanation:
Answer: 1 and 2/3
Step-by-step explanation:
Imagine 3 1/3 as if it’s in parenthesis as (3 + 1/3)
Subtract three from five.
You should get two.
Then you subtract the last 1/3 from that two.
There are three thirds in one digit.
Therefore, two thirds are left over, plus that last whole digit.
You are left with one and one third.
4-1/2x=10
-1/2x=6
3
so your answer would be B
hope that helps
