11-3(x+2)
Expand and simplify

5-3x

Step-by-step explanation:

To expand this, we start with the distribution of -3 into the parentheses containing x+2

This leaves us with

11-3x-6

From here, simplifying involves combining like terms. The only like terms we have are the constant values 11 and -6

We combine them by subtracting 11-6 to get 5.

This leaves us with our answer,

11-6-3x

5-3x

An alternate way of writing this would be

-3x+5

But this would only be required if we were asked to express the answer in decreasing degree, so don't worry about that for now

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )
