13) Based on the scatter plot, predict the value of x when y = 20.
A) 12
B) 2
C) 6
D) 8

1/5x+9 2/5y+7

step-by-step explanation:

29 is the correct answer

step-by-step explanation:

3

step-by-step explanation:

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
