Tri-State Pick 3 game: You choose a number with 3 digits from 0 to 9; the state chooses a three-digit winning number at random and pays you $500 if your number is chosen. Because there are 1000 numbers with three

digits, you have probability 1/1000 of winning. Taking X to be the amount your ticket pays you, the probability

distribution of Xis

Payoff X

SO

5500

The mean and standard deviation of X are wx = $0.50 and ox =

Probability: 0.999 0001

$15.80

Suppose you buy a 51 ticket on each of two different days

7. Find the expected payoff for the two tickets.

8. Find the standard deviation for the payout of the two tickets.

Suppose you buy a Pick 3 ticket every day for a year (365 days)

2. Find the mean of your total winnings.

10. Find the standard deviation of your total winnings

c

step-by-step explanation:

at least i think its

b i think

step-by-step explanation:

not really sure

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.

edit: i meant

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
