Answer:
£13800
Step-by-step explanation:
1150*12=£13800
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.

Simplify for -5/8*2/3= -5/12
-0.416 as a mixed number
Answer:y=5x+30
Step-by-step explanation:
The y-intercept is 30 so it is y=?+30
Then the x changes value at a constant rate of 5
So... it is y=5x+30
