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.
Given
John had a roll containing of wrapping paper

First, he must cut off 5/6 foot because it was torn.
He wants to divide it into 11 pieces.
To proof
As given in question
John had a roll containing of wrapping paper

( solving the mixed fraction form)
First, though, he must cut off 5/6 foot
than we get

Taking the L.C.M of 3 and 6 is 6


=23.83 feet (approx)
He wants to divide it into 11 piece
length of the each piece

length of the each pieces be 2.16 feet ( approx)
Hence proved
Answer:
C. 
Step-by-step explanation:
The volume of the ball with radius R can be calculated using formula

A basketball has a diameter of 9.5 cm, so its radius is

Hence, the volume of air the basketball can hold is

First let's set up an equation: 35+0.05t.
35 is the phone rate per month plus the number of texts (t) times 0.05 (cost of 1 text)
Now we can find the amount of texts she sent each month.
March
35+0.05t=72.60
-35 -35
0.05t=37.60
------ -------
0.05 0.05
t=752
April
35+0.05t=65.85
-35 -35
0.05t=30.85
------ -------
0.05 0.05
t=617
She sent 752 texts in March and 617 texts in April.
