1. Given the following set of numbers {1,1,1,1,2,3,4,5,5,5,5,6,7,8,8,8,8,8,9, 10} what is the probability of choosing a prime number, given that a factor of 36 is chosen?

B.\(\frac{2}{5}\)

C.\(\frac{1}{3}\)

D.\(\frac{2}{9}\)

2. Given two polygons, the first one having more sides than the second, let the following rule describe how to map the first polygon to the second polygon. (To help illustrate, refer to the two polygons pictured below.) Label the vertices of each polygon A, B, C, etc. Then, each vertex of polygon 1 is mapped to its corresponding vertex on polygon 2 (A to A, B to B, etc.). For all extra vertices of the first polygon (in this case G and H), they map to the final vertex of the second polygon (in this case to F). Is this rule a function? If not, why not?

A.Yes, this is a function.

B.No, functions relate only to equations and graphs.

C.No, because multiple vertices of the first polygon are mapped to the same vertex on the second polygon, which is the same as failing the vertical line test.

D.No, because this is not continuous; there is only a finite set of points, while functions (graphs) are an infinite set of points.

Our quizzes help students successfully develop the abilities and skills needed to pass the TSI Math test.
These quizzes are about solving problems, so some questions may not be exactly like problems in the book.

For those, you will need to figure out how to adapt what you’ve learned to solve the new and different problems.
If you miss a question, the quiz will show the correct answer, allowing you to self-diagnose your mistake, and then you can try similar problems until you get the questions correct.
