mtbf = mean time between failure
MTBF = 1/failure rate R(t) = e (-t/MTBF) http://www.vicorpower.com/documents/quality/Rel_MTBF.pdf
Mean Time to Repair and Mean Time Between Failure:They are Maintenance and Reliability predictors.

Mean time before failure
Yes. It stands for mean time between failure so the greater the MTBF, greater will be the longevity or lifetime of the equipment between two successive failures
On average, approximately 60% of a person's body weight is water. So for a 180-pound person, you would calculate 60% of 180 to find that about 108 pounds of that person's weight is water.

Calculate the amount of money you make per day, then multiply it with the amount of workdays you have completed and that should give you the prorated contract.

To calculate the force exerted by a person on the floor, we can use Newton's second law of motion: force = mass × acceleration. In this case, the mass would be the person's weight (mass = weight / acceleration due to gravity), and the acceleration would be the force of gravity acting on the person (acceleration = 9.8 m/s^2). By multiplying the person's weight by the acceleration due to gravity, we can determine the force exerted by the person on the floor.
From a Seller's perspective: Price is what you sell something for, cost is what you paid for it or what it cost to produce it. The difference is referred to as margin or gross profit.From a Buyer's perspective: Price is what you initially pay for an item. Cost is what it takes to maintain the item until it reaches Mean Time Between Failure (MTBF) also referred to as Life Expectancy (see UL rating to get MTBF). Example: Company Apurchases a surveillance system (whose DVR and Cameras have an MTBF rating of 6 years) for a price of $50,000.00. Company B purchases a surveillance system (whose DVR and Cameras have an MTBF rating of 18 years) for a price of $75,000.00. Based on the MTBF ratings Company A will have to purchase their surveillance system three times for an actual cost of $150,000.00 over the 18 years. Then you factor the time value of money on your savings for your final evaluation on Price versus Cost. Assuming a 6% interest rate over 18 years you would have a total of $75,000.00. Company A's Cost is $25,000 more (not counting the company labor to coordinate the system change) So it is important to evaluate MTBF in order to make the most economical purchase.

To calculate a percentage, you divide the part (e.g. observed value) by the whole (e.g. total value) and then multiply by 100. For example, to calculate a person's accuracy percentage, you would divide the number of correct answers by the total number of questions and then multiply by 100 to get the percentage.
