Mrs. Summers polled the students in her 7th and 8th grade classes to determine the number of pets each student has at home. The results for her 7th grade class are shown in the dot plot below. How many students are in Mrs. Summers' 7th grade class? What percentage of the students have at least one pet at home? Round to the nearest percent. Calculate the mean (rounded to the nearest tenth), median, and mode of the data represented on this dot plot.

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.
