A 20-person fraternity is making their weekend plans around 5 different parties in IV. Each brother will attend exactly one of t
skad [1K]

Answer:

3876

Step-by-step explanation:

Given the following :

Fraternity members = 20

They are to attend 5 different parties in groups of 4

Meaning a group = 4 persons

Atleast one brother will attend exactly one of the parties. (the brothers are indistinguishable).

Then, exactly one brother at a party (20 - 1) = 19, since they are indistinguishable.

Group members are in 4's

19C4

From: nCr = n! /(n-r)! r!

19C4 = 19! / (19 - 4)! 4!

= 19! / 15! 4!

= (19 * 18 * 17 * 16) / (4 * 3 * 2)

= 93024 / 24

= 3876

Identify whether the function graphed has an odd or even degree and a positive or negative leading coefficient.
sukhopar [10]

Answer: odd and positive

How to find number of degrees: Count the number of turns and add one. In this case you have 4 curves, so 4+1= 5.

How to find leading coefficient: look at the RIGHT side of the graph, the arrow is going towards positive infinity, thus making the leading coefficient positive.
