Answer:
The point estimate of the population mean for the confidence interval of (15,32) is 23.5
Step-by-step explanation:
We are given the following information in the question:
Confidence interval for population mean is (15, 32).
We have to find the point estimate for population mean.
Formula:

The point estimate of the population mean for the confidence interval of (15, 32) is 23.5

First we would solve both x’s
3x^2 - 5x
But 3 has the thingy thing (forgot the name haha)
Which means you have to multiply it by itself that many times which would be 
3x3=9
So now it would be 
9x- 5x = 4x 
Which leaves 7 and 4x
Now you may subtract those two
7-4x= 3x
        
             
        
        
        
Answer:
152 
Step-by-step explanation:
We know that the total surface area of a cuboid is the sum of the  surface area of all six of its faces.
We also know that each opposing side has the same surface area. Thus the total surface area is equal to:
