Hi there! The answer is k = 16
To find our answer we only need to collect the terms. In other words: we need to subtract all the values of k.
Example:

If you don't get this, you can try to understand it by using a story: in a cage, there are 18 koalas, 11 of them leave. How many are left?
18 koalas - 11 koalas = 7 koalas
18 k - 11 k = 7 k
Now we keep doing this again and again to find our final answer:

~Hope this helps you!
Hello,
First off it will be invalid for sure, the fact that adults are the target population doesn't validify anything. I would say that this study is biased because the board members only attended 1 game when there are 18 teams. Their data will only pertain to fans of the 2 teams playing each other, and not represent the population as a whole.
So the answer is that it should be invalid because of biased sampling.
I hope i helped
Have a fantastic day!
