Answer:
D) Standard deviation is 5.41
Step-by-step explanation:
We are given
count N = 9
Sum ∑xi = 113
Mean = ∑xi /N = 12.55
Standard deviation = where i = 1 to 9
upon substituting the values we get
Standard deviation = = 5.41
Answer:
6f + 3
Step-by-step explanation:

so we are going to add 4f and 2f together:
(4f + f2) + 3
And you get the expression:
6f + 3

Step-by-step explanation:
V=πr^2h
Plugin the values and solve
36=π(3)^2h
36/9π=h
h=1.27323954
The algebraic expression of the given sentence is: 7(x - 1).
<h3>How to Write an Algebraic Expression?</h3>
Let the unknown number be represented as x.
The word "difference" means subtraction which is "-". Multiplied means times.
We would have the following:
"Difference of x and 1" is: x - 1
x - 1 multiplied by 7 would be: 7(x - 1)
Therefore, the algebraic expression is: 7(x - 1).
