AC is the largest side

Step-by-step explanation:

The longest side of a triangle is opposite the largest  angle, and the shortest side is opposite the smallest angle.

longest

Step-by-step explanation:

Remember that always opposite to the largest angle you will find the longest side, since it is the side that has to join the sides that form the largest angle, so always in front of a 90º angle of the triangle rectangle, you will find the hypothenuse.

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! )
