2)hISTOGRAM
:)
Step-by-step explanation:
When you write that equation, you get 3x^2+6=81.
Solving for x:
Subtract by 6 on both sides of the equation to get 3x^2=75.
Then, divide by 3 on both sides of the equation to get x^2=25.
Finally, do the square root on both sides of the equation to get x=5.
The number is 5.

Answer:
11/25
Step-by-step explanation:
# means number
probability = # of orange marbles / # of total possible outcomes
7(red) + 3(green) + 4(blue) + 11(orange) = total possible outcomes
total possible outcomes = 25
# of orange marbles = 11
11/25; the probabilty of randomling picking an orange marble is 11/25
