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:
x=75
Step-by-step explanation:
you have to 140 and the other side doesn't have anything so you take 180 and subtract it by 140 180-140=40 so the inside angle is 40 and since you have two angles in the triangle you add them then subtract it by 180 180-(40+35)=105 so now you have the last angle for the inside so then you subtract that angle to get x 180-105=75 so 75=x
The answer is 36= 1.2.2.3.3
