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.

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
