From the 10,000 businesses listed in the telephone book, the committee chooses 150 businesses at random. Of these, 72 return the questionnaire mailed by the committee. The nonresponse rate is percent. (Give your answer as a whole number.)

The nonresponse rate is 52 percent.

Step-by-step explanation:

150 sampled:

72 returned and 150 - 72 = 78

The nonresponse rate is

Percentage that 78 is out of 150, that is:

78*100%/150 = 52%

The nonresponse rate is 52 percent.

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.
