Two high school basketball teams have identical records of 15 wins and 2 losses.

Sunnyside High School's mean score is 50 points and its MAD is 4 points. Shadyside High School's mean score is 60 points and its MAD is 15 points.

Lin read the records of each team’s score. She likes the team that had nearly the same score for every game it played.

Which team do you think Lin likes?

a
Shadyside - it has the higher average score

b
Shadyside - it has the higher average score and the higher MAD

c
Sunnyside - it has the lower average score but a lower MAD

d
Sunnyside - it has the lower average score

Just tell me how to set up the equation.

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?

Write 5 in the form of a/b using integers to show it as a rational number
