Answer:
0.4.84
Step-by-step explanation:
you divide the 40 by 100
1. Distribute the Negative Signs
2. Combine like terms
-2x^2 + 12x-7
Well the probabilities of one or more different outcomes have to add up to 100%. You can't have one outcome be 90% and another be 20% because it does not equal 100%.
So if you know the percentage of one outcome you have to subtract that from 100%
That means C is your answer.
The variable your solving for should be on the left side, so just flip it
c=a/b
24:28
52 (total books) minus 24 (fiction books) equals 28 (non fiction books)
