Answer:

Some ages that Mark could possibly be are...

16, 17, 18, 19, and 20. I found my answers because to have a job or work at a program, you have to be at <em>least</em> 16. So Mark could be 16, 17, 18, 19, or 20. He would be able to work being 21 because that is the drinking age and you are already in the adult stage and you are old enough to be responsible with what you do.

eduard

Answer: 504

Step-by-step explanation:

When we select r things from n things in a order , we use permutations.

Formula for permutation: $^nP_r=\dfrac{n!}{(n-r)!}$

Given : The number of family members who are potential kidney donors. = 9

Number of people needed to be selected for best match, a second-best match, and a third-best match ( in an order)=3

Then, the number of possible orders are = $^9P_3=\dfrac{9!}{(9-3)!}$

$=\dfrac{9\times8\times7\times6!}{6!}=504$

Hence, the number of possible orders 504.
