The reasons that the sample is representative:
The builders were chosen at random
The population included only builders who build in Vicki's town
Vickie wanted to determine the cost of building a house in her home, so the fact that the builders were from her town makes the sample more representative. Moreover, the random choosing of the builders helps to remove any biases that may be present.
If the point of the assignment is to get the most amount of cheese per dollar the answer is a.
You just divide the price with the number of ounces you buy and that will give you the price per ounce.
a = 5/(4*5) = $0.25 per ounce
b = 3.24/12 = $0.27 per ounce
c = 4.19/16 = 0.261875
therefore a is the best bang for the buck
Hope this helps :)
Let x be the unknown number.
The sum of x and seven hundred is 
Ten thousand times this sum is 
Answer:
x^2 -6x +6
Step-by-step explanation:
f (x) = x^2
g (x) = x − 3
f(g(x)) = Substitute g(x) in for x in the function f(x)
= (x-3)^2 -3
=x^2 -3x-3x+9 -3
=x^2 -6x +6
