Answer C : 3x^2+7xy-2y^2
equivalent to the following expression
Combine like terms
2x^2 + x^2 is 3x^2
4xy+3xy is 7xy
-y^2-y^2 is -2y^2
So expression becomes

Answer:
You should expect 4 of the next 20 children to enroll to be toddlers.
Step-by-step explanation:
This question is solved by proportions.
So far:
We have that of 2 + 8 = 10 children, 2 are toddlers, so the proportion of toddlers is 2/10 = 0.2.
How many of the next 20 children to enroll should you expect to be toddlers?
0.2 out of 20, so: 0.2*20 = 4
You should expect 4 of the next 20 children to enroll to be toddlers.
This is because 100% is the same as 1. You can’t have more than a 100% chance of something happening. 100% means there is no chance it won’t happen, so you can’t go higher.
You also can’t have a negative probability. 0, or 0%, means there is absolutely no chance it will happen.
So, you have to have a probability between “not a chance it will happen” (0) and “not a chance it won’t happen” (1).
