Answer:
P(x) = 3.88x -1750
Step-by-step explanation:
Profit is the difference between revenue and cost.
P(x) = R(x) - C(x)
P(x) = 4.1x -(0.22x +1750) . . . . . substitute the given expressions
P(x) = 3.88x -1750 . . . . . . . . . . simplify
The mid-point for given endpoints is (4,3)
Step-by-step explanation:
a mid-point is the point on a line segment that divides it into two equal portions.
If (x1,y1) and (x2,y2) are the coordinates of vertices of a line segment, then mid-point is given by:
given
(x1,y1) = (9,9)
(x2,y2) = (-1,-3)
The mid-point for given endpoints is (4,3)

Answer:
In this case, the 30% represents the proportion of the sample. It is a statistic that can be used to estimate a parameter of the population.
Step-by-step explanation:
In this case, the 30% represents the proportion of this specific sample (survey taken by the magazine).
It is a statistic that can be used to estimate a parameter of the population. In this case, it may be used to estimate the true proportion of "people in New York who believe that the Yankees will miss the playoffs this year".
If a new sample is taken, a new statistic will be calculated that may or may not be equal to 30%.
