What the heck do i type above 3

There is a fee of $2.50 that is independent. There is also the game cost, $2.25, which is dependent on how many games a person plays.

The equation is 2.50 + 2.25x = 9.25

Solving the equation:

2.50 + 2.25x = 9.25

2.25x = 6.75

x = 3

You can bowl 3 games.

Hope this helps!! :)

1/5^2 = 7.56/45

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! )
