Answer:

Step-by-step explanation:
Given that x and y are proportional and the equation relating them is
y = rx ← r is the constant of proportionality
To find r use any ordered pair from the table
Using x = 9, y = 4.5 , then
4.5 = 9r ( divide both sides by 9 )
= r , that is
r = 
It's easier to write if you convert 1/4 into 0.25.

Then you use algebra to find that he ran the mile in 6.4 minutes.
This situation is a "union." To answer it, add together the probabilities 0.42 and 0.38. Result: 0.80.
