Answer:
M=-10
Step-by-step explanation:
Step 1, subtract 1/6m from both sides leaving the equation: 1/2m+2=-3
Step 2, subtract 2 from both sides leaving the equation: 1/2m=-5
Step 3, Multiply both sides by 2 leaving the equation: m=-10

Answer:
0.1353 = 13.53% probability that the lifetime exceeds the mean time by more than 1 standard deviations
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:

In which
is the decay parameter.
The probability that x is lower or equal to a is given by:

Which has the following solution:

The probability of finding a value higher than x is:

The mean time for the component failure is 2500 hours.
This means that 
What is the probability that the lifetime exceeds the mean time by more than 1 standard deviations?
The standard deviation of the exponential distribution is the same as the mean, so this is P(X > 5000).

0.1353 = 13.53% probability that the lifetime exceeds the mean time by more than 1 standard deviations
About 100. (Im not quite sure)
