Find the length of x, giving your answer to 3 decimal places. A. A) 2.309
B. B) 3.464
C. C) 0.132
D. D) 0.577

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

10 - 8 = -2

  8 - 6 = -2

etc, so -2 is the common difference
