Pt&t has a special plan offer this month. there is a 6.00 per month charge each month and calls everywhere in the united states are 0.04 per minute. what would the monthly cost be if you typically talk for 550 minutes per month

The monthly cost be if you typically talk for 550 minutes per month would be 28.

Step-by-step explanation:

The monthly cost is function of the time t, in minutes, is given by the following equation.

In which is the fixed cost and a is the cost of the minute.

pt&t has a special plan offer this month. there is a 6.00 per month charge each month and calls everywhere in the united states are 0.04 per minute.

This means that . So

what would the monthly cost be if you typically talk for 550 minutes per month

This is C(550).

The monthly cost be if you typically talk for 550 minutes per month would be 28.

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! )
