Answer:
C. Sample: listings in a local newspaper and on an Internet sitePopulation: all available apartments near the college
Step-by-step explanation:
The sample is the set of information Greg collects to do his estimation. The sample is necessarily a subset of the population. That is, in this case, the apartments listed in the local newspaper and the internet. He will estimate a mean rent for the sample and, with this result, estimate the population mean rent.
The population is the bigger set available for Greg to do the estimation, and the set he wants to estimate a parameter from (in this case, the mean rent).
In this case, the population is all the apartments near the college.
Answer:
The length is 
and the breadth is 
Step-by-step explanation:
Let
x ----> the length of a rectangular campsite
y ----> the breadth of a rectangular campsite
we know that
The perimeter of a rectangle is equal to
so
------> equation A
The area of a rectangle is equal to
so
-----> equation B
substitute equation A in equation B
Solve the quadratic equation by graphing
The solution is 
( I assume that the length is greater than the breadth)
see the attached figure
Find the value of y
therefore
The length is and the breadth is
