A shuttle bus leaves from my office at a speed of 32 miles per hour. How many hours will it take to arrive at my house if the
distance from the office to my house is 83 miles? Enter your
answer rounded to the nearest tenth of an hour.
hrs

2.6 hours

Step-by-step explanation:

use distance formula:  d = r * t

                                     83 = 32t

                                     83/32 = t

                                       2.6 = t

2.6 hours is 2 hours, 36 minutes

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! )
