Corey invested $1500 when he was a freshman in order to save for college. If he chooses to invest it in an account that earns 3.5% interest and is compounded annually, how much money will he have after 4 years?

He will have $1721.28. after 4 years.

Step-by-step explanation:

The formula we use to find the compounded amount A is :

, where P= principal value, r = rate of interest , t= time.

As per given , we have

P=$1500  , r=3.5%=0.035 , t= 4 years

Money he will have after 4 years =

Hence, he will have $1721.28. after 4 years.

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! )
