In how many ways can you fill three different positions by choosing from 15 different people? a. 3 · 2 · 1 b. 15 · 14 · 13 c. 15 · 14 · 12 · 3 d. 15 · 3 its algebra 2!

C. Because

When the seats are empty, there are a total of 15 people that can posibly sit in there. We will only let 1 person sit on a chair. 

When the 1st seat is taken there are now 14 people who can possibly sit on another chair. Same goes when 2 seaats are taken. 

To find the total number of possibilities, we multiply together the possible number of people for seat 1, seat2, and seat 3. 

Or, if we use stat, nPr = n! / (n-r)! 

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.

Yes yes yes very good
