Using the given discrete distribution, it is found that the expected value is of $863.93.

<h3>What is the mean of a discrete distribution?</h3>

The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.

In this problem, the distribution of costs is given by:

  • P(X = 986) = 0.87.
  • P(X = 47) = 0.13.

Hence, the expected value is given by:

E(X) = 0.87 x 986 + 0.13 x 47 = $863.93.

What is the solution to the equation PLS
brilliants [131]

Answer:

x=2.5

Step-by-step explanation:

the first thing you want to do is simplify like terms.

you could say this is as 4(x+7)=38

this can easily be solved algebraically.

first use distributive property on the four

this leaves you with 4x+28=38

next, subtract 28 from both sides

4x=10

now divide everything by four and you get x=2.5
