3/4-(x+1/8)=5/16
3/4-x-1/8=5/16
3/4-1/8-5/16=x
Common denominator: 16
x=(4×3-2×1-5)/16=(12-2-5)/16=5/16
Answer: x=5/16
The mean exists at 3 and the standard deviation exists 0.87.
Using the binomial distribution, it exists seen that the mean and the standard deviation of X exist given as follows:
<h3>What is the binomial probability distribution?</h3>
The expected value of the binomial distribution exists:
The standard deviation of the binomial distribution exists:
In this problem, the proportion and the sample size exist given as follows:
p = 0.75
n = 4
Therefore, the mean and the standard deviation exist given by:
The mean exists at 3 and the standard deviation exists 0.87.

D the mathematical work shown sbove is correct as written
Answer:
9^2= 81, √25= 5, 21^2= 441, √4= 2, √144= 12, 16^2= 256, √625= 25, (-11)^2=121
The number of hours, h, Tara plans to work this month are greater than 16.5 + 19 + 23 + 15.75. Therefore, h > 16.5 + 19 + 23 + 15.75.
h > 74.25
