a
Interpretation:
Value of R(t) and F(t)
Concept Introduction:
Probability is the likelihood of an event to occur.. It ranges between 0 to 1. O implies no chance of occurance while 1 implies 100% chance of occurance.
b
Interpretation:
The expected number of failures
Concept Introduction:
Probability Distribution Function is a likelihood of an event to occur for discrete random variables. Graphically, it shows how likely variables will fall under the probability area.
Exponential distribution is a probabilitydistribution which finds probability of an event to occur between independent constant rate and continous rate.
c
Interpretation:
Value of r(1) yield good approximation or not.
Concept Introduction:
d
Interpretation:
Expected number of items that fail between 1 year and 1 year+ 1 week
Concept Introduction:
Normal distribution is the probability function with continuous series. It is bell shaped distribution function where mean, median and mode are same.

- The mean repair time of a reproduction machine every time it becomes defective is 5 hours, and is assumed to be available 95% of the time. What is its mean time between failure (MTBF)?arrow_forwardA local cab company maintains a fleet of 10 cabs. Each time a cab breaks down, it isrepaired the same day. Assume that breakdowns of individual cabs occur completely atrandom at a rate of two per year.a. What is the probability that any particular cab will run for a full year withoutsuffering a breakdown?arrow_forwardConsider a product that is "settled in." Its MTBF distribution has been found to be normal with a mean of 10,000 hours and a standard deviation of 100 hours. Answer the following questions: (a) Calculate the probability of a breakdown before 8,000 hours? (b) Calculate the probability of a breakdown before 9,000 hours? (c) Would you prefer a policy of “preventive maintenance” or a policy of “breakdown maintenance” on this product? Explain your choice.arrow_forward
- A weather satellite has an expected life of 10 years from the time it is placed into earth orbit. Determine its probability of no wear-out before each of the following lengths of service. Assume theexponential distribution is appropriate.a. 5 years b. 12 years c. 20 years d. 30 yearsarrow_forwardA wheel tractor-scraper is carrying a 50,000 lb load while operating on a level grade. Assume no power derating is required for equipment condition, altitude, and temperature. What minimum value of coefficient of traction between the tractor wheels and the traveling surface is needed to overcome an equivalent rolling resistance of 12%? For the fully loaded condition 40% of the weight is distributed to the drive axle. Operating weight of the scraper when empty is 70,000 lb.6.4 (5 pts) A wheel tractor-scraper is carrying a 50,000 lb load while operating on a level grade.

A bulb will generally last about one year in normal operation.Three neighbors, James, Smith, and Walker, each has a Wizard opener in their respectivegarages. Each time a bulb burns out, James replaces both bulbs. Smith, on the other hand, replaces only the bulb that has burned out, and Walker replaces both bulbs only after both haveburned out. Assume that light bulbs fail according to an exponential law.b. What percentage of the time will Walker have only one bulb burning?arrow_forward

Assume that light bulbs fail according to an exponential law.a. Over a 10-year period, how many bulbs, on average, will each neighbor require?arrow_forwarda factory that produces a small number of items per day. In about 30% of working days the factory produces 7 units of the product, in 45% of working days it produces 8 units, and the rest of working days it produces 9 units. After production is completed, each unit is thoroughly inspected. Each unit fails inspection with probability ??. If two or more units fail inspection on the same day, the factory closes for a week to re-calibrate equipment. Say the factory opens today after being closed for a week, write a mathematical expression to calculate the probability that the factory will remain open at least 30 days before closing again.arrow_forward

Identyfying fail points.arrow_forwardTopford supplies X-Data DVDs in lots of 50, and they have a reported defect rate of 0.5% so the probability of a disk being defective is 0.005. It follows that the probability of a disk being good is 0.995. What is the probability of getting at least one defective disk in a lot of 50?
