Answer:
n+7 9
9
Step-by-step explanation:
 
        
             
        
        
        
Replace x with the binomial a - 2. 
f(a - 2) = [3(a - 2) + 5]/(a- 2)
f(a - 2) = [3a - 6 + 5]/(a - 2)
f(a - 2) = [3a - 1]/(a - 2)
f(a - 2) = (3a - 1)/(a - 2)
Done. 
 
        
             
        
        
        
Answer:
8x2-30x+27 has one root (9/4) the square of the other (3/2)
Step-by-step explanation:
8x2+30x+27 = (2*x+3)*(4*x+9)  => solution = {-3/2, -4/9}
One is not the square of the other because squares are positive.
8x2-30x+27 = (2*x-3)*(4*x-9)  => 
solution = {3/2, 4/9}   since (4/9 = (3/2)^2, therefore the preceding question is correct.
 
        
             
        
        
        
Answer: The required probability is 0.008.
Step-by-step explanation:
Since we have given that 
Probability of bachelor's degree = 0.45
Probability of working in nursing = 0.85
Probability of both = 0.4
So, Probability of getting a graduate is currently working in nursing, given that they earned a bachelor's degree would be :

Hence, the required probability is 0.008.
