Question:

In applying the Poisson probability distribution​ formula, ​P(x) equals  μx•e−μx!

Briefly describe what the symbol mu represents. Choose the correct answer below.A.The symbol mu is a variable that represents the area of each region.B.The symbol mu is a variable that represents the number of occurrences of the event in an interval.C.The symbol mu is a variable that represents the number of occurrences of the event.D.The symbol mu represents a static value.E.The symbol mu is a variable that represents the mean number of occurrences of the event in the intervals.

Answer:

μ is a variable that represents the mean number of occurrences of the event in the intervals.

Step-by-step explanation:

The Poisson distribution is often used to model the number of occurrences of an event in a certain interval.

P(x, μ)

Where the symbol mu (μ) represents the mean number of occurrences of an event x in a specified interval and the variable x represents a static value.

Therefore, the correct answer is option E, μ is a variable that represents the mean number of occurrences of the event in the intervals.

Find the difference (7a-6b+7) - (8a-2)
olga nikolaevna [1]
Hey there!

Let's set up our expression:

(7a-6b+7)-(8a-2)

In order to simplify, we can use that subtraction sign and distribute it, using the distributive property. We have:

7a-6b+7-8a+2

Notice how it's plus two, because a negative times a negative two is a positive two. Now, it's a matter of finding the like terms and adding or subtracting them. These like terms can either have no variable, or have different coefficients but the same variable. That means our like terms are the 7a and -8a, and the 7 and 2. There's no like term for the 6b. That means we have:

(7a-8a) - 6b + (7+2) =

-a - 6b + 9

Hope this helps!
