Step-by-step explanation:
The average mortgage owed by Americans is $306,500, with a standard deviation of $24,500.
From the above information, we know that,
The population mean is
The population standard deviation is
Suppose a random sample of 150 Americans is selected
Since the sample size is quite large then according to the central limit theorem, the sample mean is approximately normally distributed.
The sample mean would be the same as the population mean that is
The sample standard deviation is given by
Where 
is the population standard deviation and n is the sample size.
Therefore, the required parameters are:

The height of the triangular base of the pyramid is calculated through the equation,
h = (cos x)(18 in)
where h is height and x is half of the angle of the triangle. Since the triangle is equilateral, the value of x is 30°. Substituting,
h = (cos 30°)(18 in)
h = 15.59 in
Thus, the height of the base is approximately 15.59 inches.
The height could be 2 and the width 10 or the height could be 10 and the width could be 2.
Answer:
40 square inch
Step-by-step explanation:
1/2+1/2= 1
1+1=2
2times 4= 8
8times 5= 40
if the problem has inches in it,
the answer will always equal to a square-inch
21.6k + 11.8
I believe is the answer good luck!
