Li deposit $17,500 into a bank account that earned simple interest each year after two years he had earned $2,975 in interest if no money was a deposited into or withdrawn from the account what was the annual interest rate

the annual interrest rate is 6.1% interrest

Step-by-step explanation: first of all you would want to organize your data then set up the equation ( use the annule intrest rate formula) we know that li deposited $17,500 and he earned $2,975 in interrest after two years

you would take 17,500+ I = 2,975   (used I for interrest rate)

you then yould want to get rid of I so you would add I over to 2,975

then you will have to get i by its self by dividing 2,975 to 17,500

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! )
