Marcus is running around a track that is 3/8 of a mile long. If he runs around the track 4 1/2 times, how many miles will he have completed? This is my last question for today

1 and 11/16 miles

Step-by-step explanation:

running around once is 3/8 miles, 4 1/2 is the same as 9/2

9/2 * 3/8 = (9*3)/(2*8) = 27/16, or 1 and 11/16

1 11/16

Step-by-step explanation:

Convert any mixed numbers to fractions. Then your initial equation becomes 3/8x9/2=27/16=Simplifying 27/16, the answer is 1 11/16.

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! )
