My guess would be x = -30
        
                    
             
        
        
        
Group and factor out the greatest common factor then combine. 6(3x+y)

Answer:
required probability is .3446
Step-by-step explanation:
It is given that most expected time of completion = 90 days
Variance = 25 
We know that 

Thus the standard normal deviate is given by

Applying values we get

Using the standard table for Z we have probability corresponding to Z = -0.4 equals 0.3446
Thus required probability is .3446
