Answer:
7. 2:3<__4:1
8. 1:2<__3:6
9. 3:5>__2:4
10. 6:7>__4:8
Step-by-step explanation:
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:
9 books on each shelf
Step-by-step explanation:
43 + 29 = 72 books total
72/8 = 9 books per shelf
Answer:
16
Step-by-step explanation:
To solve this question,we will have to understand some symbols in mathematics...
For example,* means ×
/ Means÷
We have so many of them
So back to the question
2*2^3 means 2 multiply by 2 raise to the power of 3
So 2^3 is 8
Therefore,2*8 means 2×8
It equals to 16
Therefore the final answer is 16
I hope you understand it better now
