here number of failures follow Poisson distribution with parameter 1.1+(1.2)/3=1.5 failures/shift
a) expected failure in a day(3 shifts)=3*1.5=4.5
therefore from Poisson distribution P(X=5)=e-4.5*4.55/5! =0.1708
b)
expected number of failure in 1 shift =1.5
hence P(no more then 1 failure)=P(X<=1)=P(X=0)+P(X=1)=e-1.5*1.50/0!+e-1.5*1.51/1!=0.5578
c)
in 6 Hour expected number of failure =1.5*6/8=1.125
hence P(next machine failure will occur before 6 pm)=1-P(no failure in 6 hour)
=1-e-1.125*1.1250/0! =1-0.3247 =0.6753

Q3. Each time a machine is repaired it remains "up" for an exponentially distributed time with rate A. It then fails and "down", and its failure is either of two types. If it is a type 1 failure, then the time to repair the machine is exponential with rate μ!, if it is a type 2 failure, then the repair time is exponential with rate H2. Each failure is, independently of the time it took the machine to fail, a...
A manager is trying to decide whether to buy one machine or two. If only one machine is purchased and demand proves to be excessive, the second machine can be purchased later. Some sales would be lost, however, because the lead time for delivery of this type of machine is six months. In addition, the cost per machine will be lower if both machines are purchased at the same time. The probability of low demand is estimated to be 0.20...
In your judgement, and given only the facts described in this case, should the management of Massey energy Company be held morally responsible for the deaths of the 29 miners? Explain in detail. Suppose that nothing more is learned about the explosion other than what is described in this case. Do you think Don Blankership should be held morally responsible for the deaths of the 29 miners? Explain in detail. Given only the facts described in this case, should the...

Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
