heelpp m leo spent the same amount of time working on each of 5 different weight machines and then spent 2/3 of an hour on the treadmill. if he spent a total of 1_3/ 4 hours at the gym, which shows the correct equation and solution for x, the number of hours leo spent at each of the weight machines? a), 5x+2/3=1_3/4; leo spent 13 minutes at each machine b).5x+2/3=1_3/4; leo spent 29 minutes at each machine c).2/3x+1_3/4=5; leo spent 5 minutes at each machine d).2/3x+1_3/4=5; leo spent 10 minutes at each machine

The answer is A.

Step-by-step explanation:

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! )

no he doesnt because "-16' is negatiive
