Answer:
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.
X= 95
z=180
y=147
based on from making sure each triangle added up to 180 degrees and with the outer angles
Answer:
x = 24
Step-by-step explanation:
T = 24.93 + 0.21x Substitute 30.18 for T
30.18 = 24.94 + 0.21x
-24.94 - 24.94 Subtract 24.94 from both sides
5.24 = 0.21x Divide both sides by 0.21
x = 24.95 ≈ 24 because you can't have a partial text message.
