Dev has a rectangular garden in his backyard. The length is 2 feet greater than twice the width. A. Write an equation to determine the perimeter of the garden.

B. What is the perimeter of Dev’s garden if the width is 5 feet?

Step-by-step explanation:

L = 2W + 2 (length is 2 ft greater than twice the width)

A.  The perimeter of the garden is P = 2L + 2W, which here is:

     P = 2(2W + 2) + 2W, or P = 4W + 4 + 2W, or P = 6W + 4

B.  If W = 5 ft, then P = 6(5 ft) + 4 ft = 34 ft

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! )
