Range = highest - lowest
3000 - (-250) = 3250
n=# of nickels
q=# of quarters
$12 is 1200 cents
5n+25q=1200
n=q
substitute q for n or n for q
5q+25q=1200
30q=1200
q=1200/30
q=40 quarters and therefore n=40 nickels
40 quarters is $10 and 40 nickels is $2, therefore you have $12
Hope this helps.
Answer:

Step-by-step explanation:
Residual value the difference between the observed value of the dependent variable and the predicted value is called the residual.
Residual ,
, where R is the residual value, O, is the observed value, and P is the predicted value. The sum and the mean of the residuals are equal to zero.
Now, we can see that the biggest <em>magnitude </em>of the difference is of
and
is at the point
. (
)
Therefore, the point farthest from the line of best fit is the one whose magnitude of residual value is the most and in this case that point is
.
Welp that was wrong sorry lol. Uuh, what he said^ :
75,000 x .04 = 7,000 (agency fee)
4,725 / 7,000 = .675 or 67.5%
no rounding necessary.
