Answer:
Here is the answer...hope it helps:)
Because the teacher only picked 5 students out of all the students it was a sample.
If the teacher had asked every student, it would have been a population.
Multiplication and division are opposites, or inverse operations
Start with the first sentence, and the definition of the area of a rectangle:
l * w = 36
Rewrite the equation to get
l = 36 / w
or
w = 36 / l
Either one shows the inverse relationship between w and l.
Assuming the last part wants you to write an equation for an x-y graph, the equation would be
y = 36 / x
