Line k passes through the points (0,4) and (3,13). write the equation of line k

y = 3x + 4

Step-by-step explanation:

To find the slope, you need to subtract 4 from 13 and 0 from 3. So this will look like 9/3, which would be 3. To find the y-intercept, plug in one of the coordinates, so let's take (0, 4) since it's easier. If you plug in the 0 as the x and the 4 as the y in the equation, it should look like, 4 = 3(0) + b. 0 times 3 is 0, so that makes the b (y-intercept) 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! )

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.
