Reasons:
The given parameters are;
The number of swimmers available = 6 swimmers
The number of swimmers the coach must select = 4 swimmers
Required:

Answer:
x = 39
Step-by-step explanation:
We know that PRQ is a right triangle, so we use the pythagorean theorem to solve the problem. The theorem states that a^2 + b^2 = c^2. Let's assume that the length of RP is c, the length of PQ is a and x is b. We plug the lengths into the equation and solve it:
80^2 + x^2 = 89^2
6400 +x^2 = 7921
x^2 = 1521
x = 
x = 39
Answer:
97.5
Step-by-step explanation:
75,85,90,105,120,150
90 and 105 are the middle, and median means the middle, but you can only have one answer.
90+105=195
195÷2=97.5
97.5 is the middle of all these numbers
