number situation. the difference of a number and seven A 1-column table with 5 rows. Column 1 is labeled Subtraction Words with entries decreased by, difference, fewer, less than, subtract. Which statements are true? Select all that apply. You can replace “a number” with a variable to represent an unknown value. You can replace “difference” with a division sign. You can replace “difference” with a subtraction sign. You can replace “seven” with 7. The correct expression is n – 7. The correct expression is 7 – n.

the right answer is 1,3,4,5

Step-by-step explanation:

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! )

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
