Exercise 9.15. omar and cheryl each run a food truck on a university campus. suppose that the number of customers that come to omar’s truck on a given day has a poisson(220) distribution, whereas the number of customers that come to cheryl’s truck on a given day has a poisson(210) distribution. what can be said about the probability that more customers will come to omar’s truck than cheryl’s truck in the long run? provide random variables for the number of customers arriving to each food truck each day and give a clear mathematical statement. be precise about the assumptions you are making

the answer is  

a.

4,624π mm2

step-by-step explanation:

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
