The ordered pairs below represent a linear function (3/4, 6 1//4), (1 1/4, 7 3/4), (x, y). which values could be the values of x and y?

(0, 4) or any point on the line y=3x+4

Step-by-step explanation:

Find the slope of the equation

7 3/4-6 1/4

1 1/4-3/4

Which is 1.5/0.5, which simplifies to 3. Plug that slope into the equations.

y=mx+b, 6 1/4=3*3/4+b, b=4.

Now the equation is y=3x+4

Any point on this line is a solution, such as (0, 4)

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! )

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
