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.

Answer:
400 sixes
Step-by-step explanation:
Find how many sixes you could expect to roll by multiplying 500 by 4/5:
500(4/5)
= 400
So, you would expect to roll 400 sixes
Hello!
Explanation:
Distributive property: a(b+c)=ab+ac
Multiply by the numbers.
Product it's going to be multiply by the numbers, fractions, decimals, factors, and multiples.
First, apply used their FOIL.
Foil: (a+b)(c+d)=ac+ad+bc+bd
2x*7x+2x(-6z)+5z*7x+5z(-6z)
Then you can also apply by the minus/plus sign.
2*7xx-2*6xz+5*7xz-5*6zz
And finally simplify by equation.
2*7xx-2*6xz+5*7xz-5*6zz
<em><u>Answer: =14x²+23xz-30z²</u></em>
Hope this helps!
