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:
Hence, the expected value is given by:
E(X) = 0.87 x 986 + 0.13 x 47 = $863.93.

<h3>
The complete exercise is: "Line segment YV of rectangle YVWX measures 24 units. What is the length of line segment YX?"</h3><h3>
The missing figure is attached.</h3>
Since the figure is a rectangle, you know that:
Notice that the segment YV divides the rectangle into two equal Right triangles.
Knowing the above, you can use the following Trigonometric Identity:
You can identify that:
Therefore, in order to find the length of the segment YX, you must substitute values into and then you must solve for YX.
You get that this is:
Answer:
The slope of the line is 2

Answer:
11,232,000 different plates
Step-by-step explanation:
Figure it out like this:
2letters × 3digits × 1letter
Nothing can repeat. There are 26 letters in the alphabet. If we use 1 of those letters, then there are only 25 letters left to choose from. That's why we start with 26 × 25.
Now for the digits, we have 10 choices for the first digit, then 9 choices for the second digit, then 8 choices for the third digit. That's why we follow the letters with 10 × 9 × 8.
For the last letter, we had 24 choices left, so the whole thing is found by multiplying:
26 × 25 × 24 × 10 × 9 × 8 × 24 = 11,232,000
