Aldo wants to install a skylight in the roof of his house. The base of the skylight is a regular hexagon with side length 40 cm. What is the perimeter of the base of the skylight? Give your answer in metres. Which strategy did you use to find out?

the perimeter of the base of the skylight is 2.4 meters

Step-by-step explanation:

The perimeter of a shape or figure is the distance around it. The base of the skylight is a regular hexagon with side length 40 cm. It means that it has 6 sides and all the sides are equal.

Therefore, the the perimeter of the base of the skylight would be

40 × 6 = 240 cm

We would convert from cm to meters.

100 cm = 1 m

Therefore, 240 cm would be

240/100 = 2.4 m

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! )
