Mrs. Fitzgerald rents a stall in a mall where she sells antiques. She earns a mean revenue of $500 per month with a standard deviation of $125. Her stall and new inventory costs her $225 per month and are her only costs.
She calculates her profits using this formula:

What will be the mean and standard deviation of the distribution of Mrs. Fitzgerald's profits?

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
