Answer:
hey u have any pictures that can explain it
The values that exist two standard deviations above and below the mean are 681 and 265.
<h3>How to determine the values?</h3>
The given parameters exist:
Mean = 473
Standard deviation =104
The values above and below the mean exist calculated utilizing:

In this case n = 2.
So, we have, 
The value above is:
x = 473 + 2
104 = 681
The value below is:
x = 473 - 2
104 = 265
Therefore, the values that exist two standard deviations above and below the mean are 681 and 265.

There’s no picture attached..... if you attach one I can help!
Absolute value makes all things inside positive (make result positive)
so one example is
|x+1|=4
so if you had 3 in it woul dyhave
|3+1|=4
|4|=4
4=4
true
if -5
|-5+1|=4
|-4|=4
4=4
