Explain how you solved the following problem

8

Step-by-step explanation:

X + 2 = 10

Carry over the 2 by the 10 - > X = 10 - 2

X = 10 - 2

X = 8

To find out if the answer was correct - > X(8) + 2 = 10

Hey!

Solution:

x + 2 = 10

x + 2 - 2 = 10 - 2

x = 8

Explanation:

So how I solved this expression was writing it then subtracting 2 from both sides of the equation to make x by it self. After simplifying the answer would turn out to be 8.

Hope this helped, good luck!

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! )

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
