The standard formulation used by the GreatCoat Paint Company for its interior wall paint enables a 1-gallon can to cover 250 square feet. The company's research laboratory produces a new formulation, and

management is anxious to show that it covers the same area, not less. The experiment involves 20 cans of

the new formulation, and this sample gets mean coverage of 237 square feet with a standard deviation of 25

square feet. (17 pts)

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
