Answer:
   f(x) = -4x^2 +48x -129
Step-by-step explanation:
It usually works well to compute the square first. That is, simplify according to the order of operations.
   f(x) = -4(x^2 -12x +36) +15
   f(x) = -4x^2 +48x -144 +15
   f(x) = -4x^2 +48x -129
 
        
                    
             
        
        
        
Answer:
P(2 quarters) = 19/ (13*16) = 19/208  = 0.0913
Step-by-step explanation:
probability of getting 2 quarters?
ok
first draw:  there are 20 quarters to choose from
second draw: there are 19 quarters left to choose
so Total coins are 65 coins
P(2 quarters) = P( 1st quarter)* P(2nd quarter)
P(2 quarters) =  20/65   *   (19/64)
P(2 quarters) = 4/13 *  19/64
P(2 quarters) = 19/ (13*16) = 19/208
 
        
             
        
        
        
It should be y=19/8.
Is it multiple choice.
