2 3 6 -29
(13 9 2 22
11x +2y - 212 - 15
O A. 2x-3y +6z--29
13x +9y + 2z--22
11x +2y +212 - 15
O B. 2x - y +6 --29
13x+9y + 4z --22
11x + 2y - 212 - 15
O C. 2x - y +62 = -29
13x +9y+z=-22
11x +2y +212 - 15
O D. 2x+3y +62 = -29
13x +9y+2z - 22

well what did you do it matters what you did : )

step-by-step explanation:

570, the answer is 570, hope it

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
