∠3 & ∠5

3.extirior angles on the same side of transversal
∠1 & ∠7

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

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

27 +27 or 27times 2=54

the diffrence is 0
