Answer:
Mean 9.2898
Standard deviation 0.006
Step-by-step explanation:
Let m and s the mean and standard deviation of the non-logarithmized
distribution and , the mean and standard deviation of the logarithmized one.
m = 10,827
Since the CV=0.4, then
s/m=0.4 and
s = 10,827*0.4 = 4,330.8
The mean of the logarithmized distribution is
and the standard deviation is
Answer:
x = (4r +3)/(r +2)
Step-by-step explanation:
Collect x terms, then divide by the coefficient of x.
x(r +2) = 4r +3
x = (4r +3)/(r +2)
