The table shows data from a concession stand, representing weekly sales (x) in dollars and profit (y) in dollars. A 2-column table with 9 rows. Column 1 is labeled x with entries 1,250, 1,485, 1,535, 1,880, 1,950, 2,005, 2,425, 2,535, 2,675. Column 2 is labeled y with entries 755, 905, 930, 1,140, 1,175, 1,215, 1,480, 1,535, 1,625. When using the median-fit method with summary points (1,485, 905), (1,950, 1,175), and (2,535, 1,535), what is the approximate slope of the best-fit model?

4 puzzles in 3 hours

step-by-step explanation:

it is 570

step-by-step explanation:

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

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50
