-s/7-4+3f
Replace s with 14 and f with -8.
-14/7-4+3(-8)
Follow the order of operations: do multiplication and division first, then addition and subtraction.
-2-4-24
Solve:
=-30.
The answer is -30.
Each variable that doesn’t have a number in front of it is an invisible 1. Since y, y, and y are like terms because they have the same exponent and variable. Because they are like terms you can add and subtract them. So 1y+1y+1y= 3y
Answer:
The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.
Step-by-step explanation:
Central Limit Theorem
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean
and standard deviation 
3% of books borrowed from a library in a year are downloaded.
This means that 
SRS of 75 books.
This means that 
What are the mean and standard deviation of the sampling distribution of the proportion of downloaded books
By the Central Limit Theorem
Mean: 
Standard deviation: 
The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.
First, isolate x.
9x^2 = 25
You can actually square root both sides of the equation:
3x = 5
x = 5/3
