What is the area of this trapezoid?

18

Step-by-step explanation:

Area = h*(b1+b2)/2

well b1 is 4 and b2 is 8 because 4+4

to find h you need to know pythagorean theorem which is a^2+b^2=c^2

well c is always the longest measurement and directly across from the right angle so in this case it is 5. a is just the base which is for so you can just plug that into a calculator to get b as 3.

b is your height so now you have everything you need to know in order to get the answer

h = 3

b1 = 4

b2 = 8

step-by-step explanation:

i could only see the first page. the other pages were blurry. ; -;

x hot dogs for 2$, y drinks for 3$. 29 items and total 70

2x+3y=70

x+y=29

if x=17and y=12

2(17)+3(12)=70

34+36=70

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! )
