(1 point) heights (in centimeters) and weights (in kilograms) of 7 supermodels are given below. find the regression equation, letting the first variable be the independent (x) variable, and predict the weight of a supermodel who is 177 cm tall.
height -172 & 166 & 168 & 176 & 178 & 174 & 172
weight -52 & 47 & 50 & 55 & 58 & 54 & 53

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8
