Abook has 200 pages. the number of mistakes on each page is a poisson random variable with mean
0.01, and is independent of the number of mistakes on all other pages.
(a) what is the expected number of pages with no mistakes?
(b) a person proofreading the book finds a given mistake with probability 0.9. what is the expected number of pages
where this person will find a mistake?
(c) what, approximately, is the probability that the book has two or more pages with mistakes?

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

don't report but were is the digram

step-by-step explanation:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
