All values are identical.
Step-by-step explanation:
We are given the following in the question:
If the standard deviation of a set of data is zero.
Then, all the values in data are identical.
This can be shown as:
Let all the terms in data be x.
Formula:
where 
are data points, 
is the mean and n is the number of observations.
Sum of squares of differences =
Thus, the correct answer is
All values are identical.
Answer:
x=17
Step-by-step explanation:
3x+5+2x=90
5x=85
x=17
The answer is A because The Commutative Property of Addition states that no matter how the problem is structured you would still get the same answer and answer A expresses that
It would be 8√17 because the seventeens don't change only the one that subtracting 9.
