Answer:
The average number of points this player will get in 100 one-and-one free throw situations is 70.
Step-by-step explanation:
For each free throw, there are only two possible outcomes. Either the player makes it, or he does not. The probability of the player making a free throw is independent of other free throws. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:

70% free throw percentage.
This means that 
What is the average number of points this player will get in 100 one-and-one free throw situations?
This is E(X) when n = 100. So

The average number of points this player will get in 100 one-and-one free throw situations is 70.
Answer:
I belive the first one is 5:7 And the second one is 7:12
Step-by-step explanation:
I think it is 90 :p (Good Luck)
Find common variables. I wrote the ones I found above the polynomial. write them in parentheses the first number will have the variable. now it's just a matter of figuring out how to order it so that the first terms added to the second terms equal to the middle term of the polynomial. ... I think this is right. you could always look on wikiHow if I'm wrong.
