Answer:
Step-by-step explanation:
Let the other number = x
x + 40 = 73
Subtract 40 from both sides
x + 40 - 40 = 73 - 40
x = 33
One way is to solve for the inverse of the first function
remember, to solve, replace f(x) or g(x) with y, switch x and y, solve for y and replace it with 
A.



nope, not A
<h3>What is the inverse function?</h3>
The inverse function of a function f is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by 
B.

![f^{-1}(x)=\sqrt[3]{((x-16)/3)}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Csqrt%5B3%5D%7B%28%28x-16%29%2F3%29%7D)
nope, not the same
not B
C.

The correct, answer is C.

The value of the z statistic for the considered data is given by: Option A: -3.87 approximately.
<h3>How to find the z score (z statistic) for the sample mean?</h3>
If we're given that:
- Sample mean =
- Sample size = n
- Population mean =
- Sample standard deviation = s
Then, we get:

If the sample standard deviation is not given, then we can estimate it(in some cases) by:

where
population standard deviation
For this case, we're specified that:
- Sample mean =
= 2.3 - Sample size = n = 15
- Population mean =
= 2.7 - Population standard deviation =
= 0.4
Thus, the value of the z-statistic is evaluated as:

Thus, the value of the z statistic for the considered data is given by: Option A: -3.87 approximately.
