Find the coordinates of the midpoint M of ST. Then find the distance between points S and T. Round the distance to the nearest tenth.

S(6,−3) and T(7,−2).

answer: answer is b.

[m < b = 120º]

step-by-step explanation:

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

they charge the same amount at 20 minutes.
