Problem #4:
Explain why 3x^2 can be said to be in both standard form and factored form.

do you have any choices

step-by-step explanation:

true? is that what you're asking or do you mean something else?

-2/

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
