The table shows the number of grade 7 and grade 8 students on the student council at Jeremy’s school.
Grade Levels of Student Council Members
Number of Students
Grade 7
17
Grade 8
34
Every day, two student council members are randomly chosen to read the morning announcements. Students cannot be chosen more than once to read the announcements. Jeremy designed a simulation for the selection of the students and gathered data to predict the probability that a seventh grade student will be chosen. In Jeremy’s simulation, he rolls two number cubes in each of 40 trials. In each trial, a cube landing on 1 or 2 represents a student in grade 7 being selected, and a cube landing on 3, 4, 5, or 6 represents a student in grade 8.
Which statement best describes the flaw in Jeremy’s model?
The number of sides on a cube does not match the number of grade levels.
The number of sides on a cube is not a factor of the total number of students.
The number of outcomes representing each grade level does not change after the first student is chosen.
The number of outcomes representing a student in grade 7 is not the same as the number representing a student in grade 8.

The change in water level of a lake is modeled by a polynomial function, w(x). described how to find the x-intercepts of w(x) and how to construct a rough graph of w(x) so that the parks department can predict when there will be no chage in the water level. you may create a sample polynomial of degree 3 or higher to use in your explanations.
