Answer:
The number of student numbers that are possible = 729,000,000 student numbers
Step-by-step explanation:
The number of possible numbers that can take the place of the first two digits = 9 possible numbers each
The number of possible numbers that can take the place of the 3rd to the 9th digits = 10 possible numbers each
The number of possible numbers that can take the place of the 10th digits = 9 possible numbers each
The total number of possible numbers is given as follows;
9 × 9 × 10⁶ × 9 = 729000000 possible student numbers
Answer: a. 50 African Americans
b. Pool B will have a smaller p-value because that pool's number of AA people is further from the hypothesized number of AA people.

Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
The volume of a cone is given by the formula
![V=\frac{1}{3}\pi r^{2}h](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E%7B2%7Dh)
we have
![h=2x\ units\\r=x\ units](https://tex.z-dn.net/?f=h%3D2x%5C%20units%5C%5Cr%3Dx%5C%20units)
substitute
![V=\frac{1}{3}\pi x^{2}(2x)](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%5Cpi%20x%5E%7B2%7D%282x%29)
![V=\frac{2}{3}\pi x^{3}\ units^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B2%7D%7B3%7D%5Cpi%20x%5E%7B3%7D%5C%20units%5E3)
