ontractor decided to build homes that will include the middle 80% of the market. if the average size of homes built is 1750 square feet, find the maximum and minimum sizes of the homes the contractor should build. assume that the standard deviation is 96 square feet and the variable is normally distributed

3/8

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
