20 air conditioning units for use in the international space station operated for 1,000 hours One failed after 200 hours and one after 600 hours

.0153 failure/trip

Explanation:

Calculation to determine the Failure rate (FR)

First step is to calculate the FR(%)

FR(%)=2/20 (100%)

FR(%)=10%

Second step is to calculate the FR(N)

FR(N)= Failure/unit hr=2/[(20*1,000hrs)-(1,000 hrs+200 hrs)]

FR(N)= Failure/unit hr=2/20,000 - 1,200

FR(N)= Failure/unit hr=2/18,800

FR(N)= Failure/unit hr=000106

Now let determine the FR

FR = (.000106)(24hrs )(6 days/trip)

FR = .0153 failure/trip

Therefore the Failure rate (FR) is .0153 failure/trip

answer; management is about coping complexity and leadership is about coping with change; i believe this is correct; ///good luck                                          

(b) management: leadership
