Answer:
E
Step-by-step explanation:
Confidence Interval = mean + or - error margin
Mean = 42,000, error margin = width of estimate of the parameter ÷ 2 = 175 ÷ 2 = 87.50
We can be 95% confident that the population mean is 42,000 plus or minus 87.50
Answer:
hi
Step-by-step explanation:
the function is c(x) = 31 + 0.18*x
where $31 is a fixed cost, and $0.18 is the cost per mile drive (where the number of miles driven)
So the fixed cost, $31, is the cost per day of rent (this price does not depend on the number x), and the linear cost, $0.18, is the cost per mile driven (because this number is multiplied by x in the function), then the right answer is B: "$31 is the cost per day to rent the car and $0.18 is the cost per mile."
Your answer would be A)
Hope this helps (:
