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.

Since you have to multiple. L×W×H....
The first one has a volume of 400 and the second has a volume of 400...so both prisms have an equal volume but have a differnet shape
Answer:
25% increase
Step-by-step explanation:
length is 24 inches after the increase and width is 33 inches (i did length as up and down and width as side to side, that's how I always do it but I might be wrong let me know and I can fix it)
the area before it gets increased it 600
after the increase its 792
and 600 is 75.75% of 792
so it would be 25.25% increase
sorry this was so long hope this helps
Answer:
20 points
Step-by-step explanation:
Points:
- 21, 13, 14 and x for the last game
Average:
- (21+13+14+x) / 4 = 17
- 48 + x = 4*17
- 48 + x = 68
- x = 68 - 48
- x = 20
They must score 20 points
Answer:
12
Step-by-step explanation:
5x + 7x + 3x = 180°
15x = 180°
x = 180°÷15
x = 12
