- Tim wrote 27 as (-3)^3. Is he correct?

no, he is not

Step-by-step explanation:

(-3)^3 is equal to -27, not 27

(-3) (-3) = 9

9 (-3) = -27

Step-by-step explanation:

he is not correct

because (–3)^3=‒3*‒3*‒3=‒27

the correct answer must be 27=3*3*3or (3)^3

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
