Hello from MrBillDoesMath!
Answer:
1 - i sqrt(11) , 1 + i sqrt(11)
Discussion:
Translating the Question into mathematical symbols:
x * y = 12 (*)
x + y = 2 (**)
From (**), y = 2 - x. Substitute this value in (*)
x * y = x * (2-x) = 12 =>
2x - x^2 = 12 => add x^2, subtract 2x from both sides
0 = x^2 -2x + 12
Solving using the quadratic formula gives
x = 1 - i sqrt(11)
and
y = 1 + i sqrt(11)
Thank you,
MrB

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.
