Answer:
0.5217
Step-by-step explanation:
Given that:
mean
= 5.8
Using Poisson Probability formula:


![= 1-[P(X=0)+P(X=1)+P(X=2)+P(X=3)+P(X=4)+P(X=5)]](https://tex.z-dn.net/?f=%3D%201-%5BP%28X%3D0%29%2BP%28X%3D1%29%2BP%28X%3D2%29%2BP%28X%3D3%29%2BP%28X%3D4%29%2BP%28X%3D5%29%5D)
![= 1 -[\frac{(e^{-5.8}*5.8^0) }{ 0! } + \frac{(e^{-5.8}*5.8^1) }{ 1! } +\frac{(e^{-5.8}*5.8^2) }{ 2! } +\frac{(e^{-5.8}*5.8^3) }{ 3! } +\frac{(e^{-5.8}*5.8^4) }{ 4! } +\frac{(e^{-5.8}*5.8^5) }{ 5! } ]](https://tex.z-dn.net/?f=%3D%201%20-%5B%5Cfrac%7B%28e%5E%7B-5.8%7D%2A5.8%5E0%29%20%20%20%20%7D%7B%200%21%20%20%20%7D%20%2B%20%5Cfrac%7B%28e%5E%7B-5.8%7D%2A5.8%5E1%29%20%20%20%20%7D%7B%201%21%20%20%20%7D%20%2B%5Cfrac%7B%28e%5E%7B-5.8%7D%2A5.8%5E2%29%20%20%20%20%7D%7B%202%21%20%20%20%7D%20%2B%5Cfrac%7B%28e%5E%7B-5.8%7D%2A5.8%5E3%29%20%20%20%20%7D%7B%203%21%20%20%20%7D%20%2B%5Cfrac%7B%28e%5E%7B-5.8%7D%2A5.8%5E4%29%20%20%20%20%7D%7B%204%21%20%20%20%7D%20%2B%5Cfrac%7B%28e%5E%7B-5.8%7D%2A5.8%5E5%29%20%20%20%20%7D%7B%205%21%20%20%20%7D%20%5D)



∴ the probability that, in any hour, more than 5 customers will arrive =0.5217
So, $175 is the total of 10 hours of his work. We have to divide the 175 to 10 so that we can get his hourly wage. 175 divided by 10 is 17.5. Multiply the 17.5 to 8 hours, its $140
Answer:
Step-by-step explanation:
area πr²=28.26
r²=28.26/π
r=√(28.26/π)≈ 9cm
Answer:
below
Step-by-step explanation:


add -36 to both sides

divide both sides by 2


This is a quadratic equation
let's solve it by graphing it
The solution are the x-coordinates of the intersection points
The x-coordinates of the intersection points are approximatively -1.6 and 5.6
Answer:
x=10
Step-by-step explanation:
first substitute y with the value (-5)
2x+5(-5)=-5 which is simplified to 2x+-25=-5
add 25 to -5 which gives you 2x=20
then divide 20 by 2 which makes x=10
