Solve for x

a. 25
b. 11 3/7
c. 28 5/7
d. 35

D. 35

Step-by-step explanation:

I set up a proportion to solve for x. I divided 14 by 8 to find the ratio. After finding that ratio to be 7/4, I multiplied 7/4 to 20 to get 35 as the answer.

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
