Let's start making our expression.
Just take the number 40 and change it around.
That's a good start.
49 is equal to 7×7, or 7². 9 is equal to 3×3, or 3².
So we can also write this as
You can really do whatever you want with it as long as it's still 40, just make sure you've got an exponent there. Here's another example.

Answer:
The point estimate for the mean endowment of all private colleges in the United States is 180.2125 million dollars.
Step-by-step explanation:
We are given endowments (in millions of dollars) of eight private colleges in the United States:
78.8, 50.3, 243.2, 489, 111.5, 163.7, 92.4, 212.8
We have to find the point estimate of the population mean endowment of all private colleges in the United States.
The point estimate will be given by the sample mean.
Formula:
Thus, the point estimate is 180.2125 million dollars.
