A square has all 4 sides the same.
When given the area of a square , you can find the length of the side by finding the square root of the area:
Side length = √215
Side Length = 14.6628
Rounding to the nearest 0.05 would = 14.65 feet.
The regression equation:
y = m x + b
m = ( 57 - 50 ) / ( 178 - 168 ) = 7 / 10 = 0.7
50 = 0.7 * 168 + b
50 = 117.6 + b
b = 50 - 117.6
b = - 67.6
y = 0.7 * x - 67.6The graph is in the attachment.
The weight of supermodel who is 171 cm tall:
y = 0.7 * 171 - 67.6 = 119.7 - 67.6 =
52.1 kg
