Answer:
Step-by-step explanation:
Yes it’s parallel because the lines do not meet
Red I know because the smaller the number the bigger the fraction
Answer:
The standard deviation of the sample is 0.0064.
Step-by-step explanation:
The standard deviation of a sample of length n of a population with standard deviation 
is given by the following formula:
In this problem, we have that:
61 randomly selected gas stations. This means that 
The standard error of the mean is $0.05. This means that 
.
What is the standard deviation of the sample?
The standard deviation of the sample is 0.0064.
One way is factor
exg
if you wanted to find the square root of 36 you would factor
36=2 times 2 times 3 times 3
then group repeeting numbers then write only one of them
36=(2 times 2) times (3 times 3)
squareroot36=2 times 3=6
so factor 65
65=5 times 13
that doesn't help
next step
find squares close to that numbers
1^2=1
2^2=4
3^2=9
4^2=16
5^2=25
6^2=36
7^2=49
8^2=64
9^2=81
the answer is a little more than 8
the more exact one would be from a calculator (8.0622577482985)
