Alocal radio station had a contest to see who could guess closest to the actual number of jellybeans that filled a small car. the number of jellybeans that were in the car was 785,000. the radio station used bags that contained 800 jellybeans each and dumped the jellybeans in the car until is was full. randall and susie had an argument about how many bags the radio station had to use to fill the car. randall claimed the radio station needed more than 981 bags. susie claimed that the radio station used exactly 981 bags to fill the car. who is correct? explain by finding exactly how many bags of jellybeans the radio station used to fill the car.

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! )

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.
