A system has two components: A and B. The operating times until failure of the two components are independent and exponentially distributed random variables with parameter 2 for component A, and parameter 3 for component B. The system fails at the first component failure. (a) - Read section 1.5.2 in the textbook.
(b) - What is the mean time to failure for component A and for component B

-- Component A

-- Component B

Step-by-step explanation:

Given

Distribution = Exponential

--- Component A

--- Component B

Solving (a): The mean time of A

The mean of an exponential distribution is:

We have:

--- Component A

Solving (b): The mean time of B

The mean of an exponential distribution is:

We have:

--- Component B

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
