The answer to your question is 8mi. I just divide the circumference by pi to find your diameter.
Answer:
The total number of pages in the e-book is 240.
Step-by-step explanation:
Given:
Logan has completed 75%
Logan has read 180 pages
To Find:
The total number of pages in the e-book= ?
Solution:
Let X be the total number of pages on the e-book
then
=> 75% of X = 180
Now lets find the value of X
X = 
X = 
X = 
X = 240
Answer:
x = -6
Step-by-step explanation:
-1.5x = 9 Divide the -1.5 on both sides
x = -6
Plug in the answer to make sure it works.
-1.5(6) = 9
9 = 9
38.4/x=100/32.5
multiple both sides of the equation by x
38.4=3.07692307692*x
divide both sides by the big number to get x
38.4/(big number)=x
x=12.48
The variance for the sample is 25
For given question,
We have been given the sample size n = 21
and the sum of squares is SS = 500
We need to find the variance for the sample.
We know that the variance is mathematically represented as,

Substituting given values in the above formula,

= 500 / 20
= 25
So, the variance is 25
Therefore, the variance for the sample is 25
