There are 8 members on a board of directors. if they must form a subcommittee of 6 members, how many different subcommittees are
Shtirlitz [24]
1. Given a group of n people. There are C(n, r) ways of forming groups of r out of n.

2. Where C(n, r)=\frac{n!}{r!(n-r)!}

3. For example, given {Andy, John, Julia}. We want to pick 2 people to give a gift: we can pick {(Andy, John), (Andy, Julia), (John, Julia)}, so there are 3 ways. So we can list and count.

4. Or we could do this with the formula C(3, 2)=\frac{3!}{2!(1)!}= \frac{3*2*1}{2*1}=3

5. C(8, 6)=\frac{8!}{2!6!}= \frac{8*7*6!}{2*6!}= \frac{8*7}{2}= 4*7=28

So there are C(8,6)=28 ways of chosing 6 out of 8 people to form the subcommittees. <span />

3,666 = 39(p +25)<br><br> 20 POINTS + BRANLIESTTT PLEASE HELP
iVinArrow [24]

Answer:p=69

Step-by-step explanation:

Let's solve your equation step-by-step.

3666=39(p+25)

Step 1: Simplify both sides of the equation.

3666=39(p+25)

3666=(39)(p)+(39)(25)(Distribute)

3666=39p+975

Step 2: Flip the equation.

39p+975=3666

Step 3: Subtract 975 from both sides.

39p+975−975=3666−975

39p=2691

Step 4: Divide both sides by 39.

39p /39  =  2691 /39
