Equilateral triangle
44
Give an example of an event that has a probability of 0
Answers will vary, any event that is impossible to happen
True or false: a line that passes through the origin on a graph does not represent a proportional relationship
False
Solve for x:
2x = 122
x = 61
A triangle with NO equal sides is called:
Scalene triangle
7 - (-7)

Explain what it means for an event to have a probability of 1/2
It has an equal chance of happening versus not happening
Find the constant of proportionality (k):
x y
1 4
2 8
k = 4
Solve for x:
4x + 20 = 3x + 45
x = 25
