First, I would multiply the last two fractions because they're smaller and easier to work with:
Now that we've simplified it, we could multiply these terms and simplify. An easier method, however, would be to cancel out any common factors among the numerators and denominators before multiplying:
We can now multiply these terms:
The <span>product of 8/15, 6/5, and 1/3 is B, 16/75.</span>
Answer:
I think it is probably the 2nd option
Step-by-step explanation:
I'm not entirely sure about the words theoretical and experimental.
I am guessing that experimental means the probability that they got in the table
And I think theoretical means what the mathematical probability should be.
As far as I can tell the theoreticall probability for each part of the pie is 33.33333....
Since each part is equal and there are 100 spins
using these definitions only option 2 makes sense
Distribute the first set of parenthesis
<span><span>15<span>r<span><span>2</span><span></span></span></span>−20r+6r−8</span><span>
Combine like terms
</span><span><span>15<span>r<span><span>2</span><span></span></span></span>+(−20r+6r)−8</span><span>
Simplify your answer
</span><span>15<span>r<span><span>2</span><span></span></span></span>−14r−8
*Answer is </span>15r^2−14r−8*<span><span>
