Use the midpoint formula to find the midpoint between s(4,5) and p(5,5).a. (4.5, 10)b. (0, 1)c. (5, 4.5)d. (4.5, 5)

midpoint ((x1+x2)/2, (y1+y2)/2)

midpoint ((4+5)/2, (5+5)/2)

 midpoint (9/2, 10,2)

midpoint (4.5,5)

Choice D

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

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
