You have a rational expression whose numerator's degree is smaller than the denominator's. This tells you you should consider a partial fraction decomposition. We want to rewrite the integrand in the form


You can use the "cover-up" method here to easily solve for  . It involves fixing a value of
. It involves fixing a value of  to make 2 of the 3 terms on the right side disappear and leaving a simple algebraic equation to solve for the remaining one.
 to make 2 of the 3 terms on the right side disappear and leaving a simple algebraic equation to solve for the remaining one.
- If  , then , then 
- If  , then , then 
- If  , then , then 
So the integral we want to compute is the same as

and each integral here is trivial. We end up with

which can be condensed as

 
        
             
        
        
        
Answer:
A whole number
Step-by-step explanation:
An integer is a whole number like 1, 2, 3. It could also be -1, -2, -3, or 0. 9.4 is not an integer. 10 is an integer.
 
        
             
        
        
        
Answer: This is a square. All sides are equal and the each angle is 90°
 
        
                    
             
        
        
        
The probability of drawing a green marble will be found as follows:
1. First, find your total number of outcomes by adding together all of the types of marbles to find the total you might draw from the bag so that you may make this a proportion. Now, you get your type of marble you want to know the probability of, and you put the total number of green marbles over this number. The total number of possibilities is 50, and the number of green marbles is 16. 
2. I'm not sure what type of answer you are looking for, but the following answers could be the following:
- 16/50
- 32%
-.32
Hope this helps.
