Raul had $60. mike had $30. each boy donated 1 tenth of his money.

which statement is true?

raul donated more money than mike did.

mike donated more money than raul did.

the boys donated an equal amount.

B.

Step-by-step explanation:

So it's B because...

So if they donated 1/10th of their money, that means they donated 10%. So, 10% of 60 is 6 and 10% of 30 is 3. which means that Raul donated more money than Mike did.

10 % of 60 = 6

10% of 30 = 3

ANSWER → B

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! )
