A nail manufacturer has an inspection process to determine whether its 1-inch nails are acceptable. The distribution of lengths of nails has a mean of 1-inch and a standard deviation
of .02 inches.
a. Only nails within 2 standard deviations are acceptable. What is the range of acceptable lengths? b. If 10,000 nails a week are manufactured, how many of them are acceptable

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.
