Answer:
The probability that no calls will occur during the next ten minutes is 0.0907.
Step-by-step explanation:
Poisson distribution:
Poisson distribution is a statistical distribution that helps to find out the number of events is likely occur in a specific time period.
![P(X=x)=\frac{e^{-\lambda t}(\lambda t)^x}{x!}](https://tex.z-dn.net/?f=P%28X%3Dx%29%3D%5Cfrac%7Be%5E%7B-%5Clambda%20t%7D%28%5Clambda%20t%29%5Ex%7D%7Bx%21%7D)
Given that,
Calls occur at an average rate of 1.2 every 5 minutes.
The average rate of call is
per minute.
Here,
, t=10 and x=0
![\therefore P(X=0)=\frac{e^{-0.24\times 10}(0.24\times 10)^0}{0!}](https://tex.z-dn.net/?f=%5Ctherefore%20P%28X%3D0%29%3D%5Cfrac%7Be%5E%7B-0.24%5Ctimes%2010%7D%280.24%5Ctimes%2010%29%5E0%7D%7B0%21%7D)
=0.0907
The probability that no calls will occur during the next ten minutes is 0.0907.
Answer:
10 . 44 ft
Step-by-step explanation:
sin 50 = opposite leg / hypotenuse = 8 / x
8 / sin 50 = x = 10 .44 ft
Answer:
2nd Option
Step-by-step explanation:
Since triangle XYZ is a 30, 60, 90° triangle, to find the sides the base is 1, the hypotenuse is 2 and the vertical side is square root 3 so that would be your ratios of the sides.
