Answer:
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 138
Average = 32.6 inch
Population variance,

We have to find a point estimate for the population variance of the height.
The point estimate for the population variance is the population variance itself.

Thus, the point estimate of population variance is the population variance that is 2.8.
Answer:
Volume is length times width times height. So, you would need to do 9 times 3 (27) times 10 (270). Then, you would divide by 10, because it is scaled down by 1/10, leaving you with 27.

Step-by-step explanation:
we know that
the sum of an exterior angle and the adjacent interior angle.of a triangle is equal to 180 degrees, because are supplementary angles
therefore
the answer is the option
An exterior angle is supplementary to the adjacent interior angle.
