The cost of 2 cartons of milk is 5.50. what is the unit price

$5.50 / 2 = $2.75

Step-by-step explanation:

Unit price - A unit price is the price of 1 item.

In this question, we have 2 cartons of milk and altogether it costs $5.50. So in order to find the price for 1 milk carton (unit price) then we need to divide 5.50 by half. So, 5.50 / 2 = 2.75

CHECK:

2.75 x 2 = 5.50      :)

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! )

y=x+9
