The double-shaded part of a system of inequalities
What is the solution?
Also acceptable: what is the solution set?

When students in this class are ordered by age, this student is the median.
Period 4: Who are Joseph and Vivian?
Period 5: Who are Mizu and Kaden?
Period 8: Who are Ezra N and Theo?
A line written as y = mx+b is written in this form.
What is slope-intercept form?
Chloe was given a box of assorted chocolates for her birthday. Each night, Chloe treated herself to some chocolates. There were originally 30 chocolates in the box and after 2 nights, there were 24 chocolates remaining in the box. Write an equation for C, in terms of t, representing the number of chocolates remaining in the box t days after Chloe's birthday.
What is C = 30-3t ?
The x-value at which these two functions have the same output.
f(x) = 6x+10
g(x) = 4x+30
What is x=10?
P = the perimeter of a regular pentagon with sides of length 5.
Q = the area of a triangle with base 10 and height 4.
Your answer is Q - P.
What is -5?
The strength and direction of a linear relationship for which r = -0.95.
This is the shape of a symmetric distribution that is highest around the median and then slowly decreases from there, ending in a "tail" on the right and left.
Most of the data (about 2/3rds) is within one standard deviation of the median.
It's not uniform.
What is bell-shaped?
The x-intercept of the line y = 5x-15
What is 3?
