The order doesn't matter. It's the combination then.

k objects can be chosen out of n objects, when the order doesn't matter, in C(n,k)=\dfrac{n!}{k!(n-k)!} ways.

So, the answer is C(6,2)=\dfrac{6!}{2!4!}=\dfrac{5\cdot6}{2}=15 ways.

Find the percent of decrease if 110 is decreased to 88 A) 125% B)80% C)20%
stich3 [128]

Hey there! I'm happy to help!

We have 110 minus a certain percent of 110 equals 88. Let's call this percent p and solve.

110-110p=88

We subtract 110 from both sides.

-110p=-22

We divide both sides by 110.

p=0.2

Therefore, the percent decrease is C) 20%.

Have a wonderful day! :D
