what is the area of a trapezoid that has a height of 12 and it’s parallel sides measure 15 and 20? Show the steps in your work.

Area of trapezoid  = 210 unit²

Step-by-step explanation:

Given:

Height = 12 unit

Parallel side a = 15

Parallel side b = 20

Find:

Area of trapezoid

Computation:

Area of trapezoid  = [(a+b)/2]h

Area of trapezoid  = [(15+20)/2]12

Area of trapezoid  = 210 unit²

24

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
