5/11 or decimal form 0.45
Answer:
C) 33%
Step-by-step explanation:
To solve for the percentage of success, we first need to find out how many numbers we are working with. In this case, there are 9 numbers (0,1,2,3,4,5,6,7,8).
Since there are 3 "successful" numbers, (0,1,2), we can write the probability as a fraction
3/9 (represents number of successes over number of possible outcomes)
This simplifies to be 33%
Okay, lets start with number 1.
is also equal to (x+3)(x+3)(x+3)
If you take the first two ones and multiple them out it ends up with
or also know as 
You see to multiply them you take the first number in the first group of parenthesis and use the distributive property on the second equation, then you do the same this but with the second number in the first equation.
So once you have
you multiply it with your remaining (x + 3) using the distributive property to get 
I hope this helps you get the answers for the other two.
