Answer:
Step-by-step explanation:
Answer:
x=5 and y=-2
Step-by-step explanation:
3x+5y=5
-(7x+5y=25)
-4x=-20
x=5
plug 5 into one of the equations. 3(5)+5y=5
y= -2
Answer:
Zero
Step-by-step explanation:
Failure Rate = 1 in every 5 hours
It is important to consider the time that it takes for 2 components to fail
* Standard deviation is not given for failure rate hence it is assumed to be zero.
What is the probability that 12 hours will elapse before 2 components fail?
In other words, what is the probability that it takes 12 hours for 2 components to fail?
This probability is = 0
This is because the time it takes for 2 components to fail is 10 hours.
No adjustment can be made for this time, as there is no stipulated standard deviation.
