The standard deviation of the set is 5.2
To find standard deviation, we take the square root of the variance.
First, let's find g(4). After we find it, we can substitute the value into
.
To find g(4), we need to substitute x = 4 into the function
, as shown below:



Now that we have found g(4) = 9, we can substitute this value in for
in
.



f(g(4)) is equal to 28.
If <span>(5^2-4) / (5+2) then
=(25 - 4 )/3
= 21/3
= 7
if 4/5 fraction then
</span><span>5^2-4/5+2
= 25 - 4/5 + 2
= 27 - 4/5
= 26 5/5 - 4/5
= 26 1/5
= 26.2</span>
