Profit, P(2), is the difference between revenue, R(x), and cost, C(2), so P(x) = R(x) - C(2) Which expression represents P(x), if R(x) = 2x4 – 3.03 + 2x – 1 and C(x) = x4 – 2? + 2.c + 3?

answer: i think you should do the math and pay attention in class : )

step-by-step explanation:

that is truly what   think but if i get the answer i will

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

the answer to this is a. a^2 + b^2 = c^2
