Bob has to interview 4 different candidates. He has to schedule each of them at different times throughout the day. How many different ways can he schedule the candidates?

 24

Label the time slots as A,B,C,D

For time slot A, he has 4 candidates to pick from. Then for time slot B he has 3 choices left (he doesn't want to interview the same person again), and C has 2 choices, with D having just one choice. Effectively we start at 4 and count our way down to 1. We will multiply these values out.

Overall, Bob has 4*3*2*1 = 24 different ways to arrange the candidate interviews. This is known as a permutation because order matters.

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
