If you were asked to convert 75 m/s to km/hr, which conversation factors would you need to use. select all that apply.

a. 1 km/ 1000 m
b. 60 min/ 1 hour
c. 60 s/ 1 min
d. 1000 m/ 1 km
e. 1 hour/ 60 min

You need to use A, B, and C.

Step-by-step explanation:

Let's treat the units as variables. I'll illustrate why in a moment.

Now, as you can see, we have a giant mess of units to deal with. This is where we can treat the units like separate variables and use a bit of algebra to make our lives easier:

So, backtracking through that entire mess, we had to use .

These correspond to the options of A, C, and B accordingly.

So you need to use A, B, and C.

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! )

-4, -2, 1, 4

domain = x values

range = y values
