The first day of class the professor collects information on each student to make a data set that will be analyzed throughout the semester. The information asked includes hometown, GPA, number of classes, number of siblings, and favorite subject. How many variables are in this data set?

The number of variables in the set is 5

Step-by-step explanation:

we us to able to understand how we arrived at 5 as the number of variables that is available in the set of data above we have to define and understand the keyword variable.

A variable; is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item.

hence by the definition of a variable we know that hometown is a variable=1,GPA is a variable=2, number of classes is a variable=3, number of siblings is a variable=4, and favorite subject is also a variable=5.

hence we conclude that the number of variables=5

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.
