The equation yˆ=−2.58x+566.67 models the distance a driver can see in feet, where x is the age of the driver in years. according to the regression equation, how far can a 30 year old driver see in feet?

A 30 year old driver can see 489.27 feet

Step-by-step explanation:

The equation yˆ=−2.58x+566.67 models the distance a driver can see in feet, where x is the age of the driver in years.

WE need to find out the height when x is 30

Plug in 30 for x  and find out y

y=−2.58x+566.67

Replace x with 30

y=−2.58(30)+566.67 = 489.27

A 30 year old driver can see 489.27 feet

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
