Answer:

1a. {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}

1b. {5}

Step-by-step explanation:

For part 1:

A U B is the union of all values, so {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}

Remember that union means to include all values.

A n B is the intersection of all values, so {5}

Remember that the intersection means "what do they have in common".

A company is holding a sales contest for its sales reps. 12 sales reps are based in Office A and 7 sales reps are based in Offic

NikAS [45]

Answer:

55,440 ways

Step-by-step explanation:

In this situation, since the bonuses are different, the order of the sales reps receiveing the bonus matters, thus permutations should be used.

The number of ways to pay the bonuses in office A (pick 3 out of 12) is:

$A=\frac{12!}{(12-3)!} =12*11*10 = 1,320\ ways$

The number of ways to pay the bonuses in office B (pick 2 out of 7) is:

$B=\frac{7!}{(7-2)!} =7*6 =42\ ways$

Considering both offices, the number of ways to pay out the bonuses is:

$N= A*B = 1320*42\\N=55,440\ ways$

Help me out please asp

Doss [256]

I would say 20

I’m not so totally sure but I believe it’s that because of the ratios, CB:CE is 3:6, and then CA:CT would probably be 10:20. does that make sense?

sorry if i’m incorrect
