Subtract 2 from one number and that answer add 3, subtract 2, and add 3 again. continue doing that.all through.
Answer:
Mean = 0.38082 checks per day
Variance = 0.38082
Standard deviation = 0.61711
Step-by-step explanation:
In a Poisson distribution, the variance (V) is equal to the mean value (μ), and the standard deviation (σ) is the square root of the variance.
A year has 365 days,, if 139 checks were written during a year, the mean number of checks written per day is:
![E(x)=\mu=\frac{139}{365}\\ \mu=0.38082\ checks/day](https://tex.z-dn.net/?f=E%28x%29%3D%5Cmu%3D%5Cfrac%7B139%7D%7B365%7D%5C%5C%20%5Cmu%3D0.38082%5C%20checks%2Fday)
Therefore, the variance and standard deviation are, respectively:
![V=\mu=0.38082\\\sigma=\sqrt{V}=\sqrt{0.38082}\\ \sigma =0.61711](https://tex.z-dn.net/?f=V%3D%5Cmu%3D0.38082%5C%5C%5Csigma%3D%5Csqrt%7BV%7D%3D%5Csqrt%7B0.38082%7D%5C%5C%20%5Csigma%20%3D0.61711)
Answer:
25/81.
Step-by-step explanation:
(27/8)^-4/3
= 8^4/3 / 27^4/3
= (∛8)^4 / (∛27)^4
= 16 / 81
(64/125)^-2/3
= (125)^2/3 / (64)^2/3
= (∛125)^2 / (∛64)^2
= 5^2 / 4^2
= 25/16
So the answer is
16/81 * 25/16
= 25/81.
