The university police department keeps track of the number of tickets it write in a year. Last year the campus police wrote 1460

AlladinOne [14]

Answer:

Step-by-step explanation:

We are given that Ticket writing on campus follows a Poisson process.

Last year the campus police wrote 1460 tickets

So, $X \sim Poisson (1460 / year)$

1 year = 365 days

So, E(Y) = $\frac{1460}{365}=4$

So, the standard deviation of the number of tickets written per day by the campus police = $\sqrt{4} =2$

Hence the standard deviation of the number of tickets written per day by the campus police is 2

How can you check if drew the right graph

crimeas [40]

If [ 2x + 6y = 18 ] was the equation you were supposed to graph, then #3 is the way to go. If it was some other equation, then you would have to slog through BOTH #1 and #2 tobe sure.
