Answer:
is it asking how many times u would get then number 5 when u roll or asking how you would expect for the first 5 rolls?
You might have to do the quadratic formula
Answer:
Mean = 4
Step-by-step explanation:
All you have to do here is multiply 30 by the number of people
so..
-3x - 3/4 = 9
-3x - 3/4 + 3/4 = 9 + 3/4
-3x = 9 3/4
I change 9 3/4 to improper fraction
-3x = 39/4
-3x / -3 = 39/4 / -3
X = 39/4 x -1/3 (change division to multiplication so that you can complete the problem)
X = -39/12
You can convert that if you want to -3 3/12
So x = -3 3/12
Simplify to x = -3 1/4
