Answer:

15 ways

Step-by-step explanation:

<u>Recall:</u>

nCk=\frac{n!}{k!(n-k)!}

n = Number of items given in a set

k = Number of objects selected from a set of n objects

<u>Given:</u>

n = 6 people

k = 4 chairs

<u>Calculation:</u>

6C4=\frac{6!}{4!(6-4)!}=\frac{720}{24(2)}=\frac{720}{48}=15

Therefore, there are 15 different combinations.

I need some help on this math problem, thanks so much

Answer:

The answer is C.

Step-by-step explanation:

Hit 'em with the Law of Sines.

sin(A)/a = sin(B)/b.

Let's say x is equal to "A", thus 5 is "a".

sin(x)/5 = sin(B)/b.

We could go for the obvious choice for "B", which would be the 90 degrees shown. To solve for the hypotenuse which will be "b", let's use the Pythagorean Theorem:

a^2 + b^2 = c^2

5^2 + 20^2 = c^2

25 + 400 = 425

sqrt(425) = about 20.6, which we can now substitute "b" with.

sin(x)/5 = sin(90)/20.6

sin(x)/5 = 1/20.6

sin(x)/5 = 0.04854...

sin(x) = 0.2427...

You can plug in sin^-1(0.2427) into your calculator, and you should end up with something like 14.047... which equates to answer choice C.
