Are circles with the same center always the same size?
a) yes, if they have the same center then they are the same circle.
b) no, it is not possible for two circles to be the same size with the same center.
c) sometimes, if they have the same center and the same radius length they will be the same size.
d) sometimes, if they have the same center and the same chord length then they will be the same size.

Option C. sometimes, if they have the same center and the same radius length they will be the same size

Step-by-step explanation:

we have two cases

First case) Two circles of the same center and same size (length of radius)

example

Center ,

Center ,

Second case) Two circles of the same center, but different size (length of radius)

example

Center ,

Center ,

therefore

sometimes, if they have the same center and the same radius length they will be the same size

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! )

linear
