This is a combination problem.
The formula is n! / (r!(n-r)!
where n is the total number of people and r is the number of people to be picked.
n = 15, r = 4
15! / (4!(15-4)!)
15! / (4!*11!)
Total combinations = 1,365
Answer:
(-1,4)
-1 is x and 4 is y
You have to plug it in for the equation:
4= 3(-1)+5
4= -3+5
4 = 2
the answer is no solution because 4 does not equal to 2

Z-score=
Substituting the values in the above equation, we find
Z-score= =2
So, the Z-score is +2
Now, the corresponding value of Z-score 2 in the table is 0.9772
or the percentile score is 97.72 ~ 97.5
