Which of the following polynomials is not factorable?
a. 3n^2-24n+36
b. 3b^3-3b^2-18b
c. 12x^2-xy-20y^2
d. 6x^2-7x+6

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
