Answer:
The probability is  16%
  16% 
Step-by-step explanation:
From the  question we are told that   
      A  is the event that  the chip was "made by company A"
       B is  the event that a chip "survives 500 temperature cycles"
     The probability that a computer chip survives more than 500 temperature cycles is 
       %
% 
  The  probability that does not survive more than 500 temperature cycles and  it was manufactured by company A is  
The probability that the  computer chip is not manufactured by company A and does not survive more than 500 temperature cycles is mathematically evaluated as 
       
Where  are a A and B complements and  | represented AND operator
 are a A and B complements and  | represented AND operator  
   So  
         ![P(B' n A ' ) = [1 -  P (B' | A )] [1 - P(B )]](https://tex.z-dn.net/?f=P%28B%27%20n%20A%20%27%20%29%20%3D%20%5B1%20-%20%20P%20%28B%27%20%7C%20A%20%29%5D%20%5B1%20-%20P%28B%20%29%5D)
substituting values 
          ![P(B' n A ' ) = [1 -  0.73] [1 - 0.42 ]](https://tex.z-dn.net/?f=P%28B%27%20n%20A%20%27%20%29%20%3D%20%5B1%20-%20%200.73%5D%20%5B1%20-%200.42%20%5D)

Answer:
this one 1/5 = 3 x a
Step-by-step explanation:
1/5 =3×a  (divied both side by 3) 
a= 1/5 ÷3
 
        
                    
             
        
        
        
Answer: it's impossible to obtain 78
Step-by-step explanation: Since the calculator can double any number or permute its digits except 0 
starting with number 1 
1, 2, 4, 8, 16, 32, 64, 128
Therefore, it's impossible to obtain 78 by a series of these operations

X intercept is when y = 0 so 4x = -20, x=-5 
y intercept when x = 0 so -5y = -20, y=4
