Chad is rolling a number cube numbered form 1-6: what is the probability of rolling a 4?
1 out of 6
Simplify:
-4b + 8b -2b
2b
-5(s + 30)= 60
-42
Define : Mean
the Average Number
15 - (-12)

Chad is rolling a number cube numbered form 1-6: what is the probability of rolling a 3 or 5?
2 out of 6
Simplify: -5v + (-2) + 1 + (-2v)
-7v -1
-2(x + 5) = 4
x=-7
Define Median
the middle number
3 - (-9)

Chad is rolling a number cube numbered form 1-6: what is the probability of rolling a 0?
impossible
Simplify:
3 - 6n - 2n + 9
-8n + 12
x + 5 < 7
x < 2
Define Inference
A conclusion made by interpreting data.
12 - (-12)

50%
Simpilfy:
4 -2y + 8y
6y + 4
x - 4 > 12
x >16
Define Probability:
Likelihood/Chance
-17 + (-13)
