Sophia and isabella share a reward of $117 in a ratio of 1 : 8. what fraction of the total reward does sophia get?

Fraction of Sophia = $ 13.

Step-by-step explanation:

Given  :Sophia and Isabella share a reward of $117 in a ratio of 1 : 8.

To find : What fraction of the total reward does Sophia get.

Solution : We have given

Sophia and Isabella share a reward of $117 in a ratio of 1 : 8.

Total part  = 1+ 8 = 9.

Sophia share = 1 out of $117.

Isabella share = 8 out of  $117.

Fraction of Sophia = .

Fraction of Sophia = $ 13.

Fraction of Isabella = .

fraction of Isabella = $104

Total $ 104 + $ 13 = $ 117.

Therefore, Fraction of Sophia = $ 13.

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! )
