a taxi hurries with a constant speed of 38 miles per hour. how long will it take to travel a distance of 95 miles

2.5 hours aka 2 hours and 30 minutes  

Step-by-step explanation:

use unit analysis:

when you set up an equation like this, make sure you set it up so you end up with the unit you want. your question asked how long, whihc means our answer was going to be a unit of time, in this situation: hours.

so the given distance was 95, multiply that by the rate of change and make sure miles is in the denominator so that the "miles" get cancelled out and you're left with the unit of hours.

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! )

slope is 35 and 20 miles is the y-intercept.
