Suppose that two electronic components in the guidance system for a missile operate independently and that each has a length of

life governed by the exponential distribution with mean 1 (with measurements in hundreds of hours). Find the probability density function for the average length of life of the two components.

Answer:

The probability density function for the average length of life of the two components is f(x) = 0.5e^{-0.5x}

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following probability density:

f(x) = \mu e^{-\mu x}

In which \mu = \frac{1}{m} is the decay parameter.

Each missile has a length of life governed by the exponential distribution with mean 1 (with measurements in hundreds of hours). Find the probability density function for the average length of life of the two components.

2, each with mean 1 means that m = 2*1 = 2, \mu = \frac{1}{2} = 0.5

So the probability density function is:

f(x) = 0.5e^{-0.5x}

Gia got some books from Library yesterday she got five books today Gia returned three books Gia has six books how many books did
makvit [3.9K]

Answer: 4


Explanation:


You can write an algebraic expression to represent the sequence with the books in this way:

  • yesterday she got five books: 5
  • today returned three books: - 3
  • how many books did Gia have to begin: n
  • At the end she has six books, which means that you can set an equality:

       n + 5 - 3 = 6

Now you follow these steps to clear the unknown:

  • do the operations in the left side: n + 2 = 6
  • use subtraction property of equality: n = 6 - 2
  • do the operations: n = 4

And that is the number of books whith which Gina started: 4

Look at the figure, FHJM. find the length of HJ​
Nat2105 [25]

Answer:

HJ=42\ m

Step-by-step explanation:

we know that

In a parallelogram opposite sides are equal and parallel

The figure FHJM is a parallelogram

so

FH=JM=36\ m

HJ=FM=42\ m

therefore

HJ=42\ m
