Ответ:
x = 2
Step-by-step explanation:
10 -4 (2x-1) = -2(3-x)
10 - 8x + 4 = -6 + 2x
-10x = -6 -10-4
-10x = -20
x = -20/-10
x = 2
Ответ:
2
Step-by-step explanation:
10-4(2x-1)=-2(3-x)
10+4-8x=-6+2x
14+6=8x+2x
20=10x
x=2
Ответ:
a) What is the probability that the duration of a particular rainfall event at this location is at least 2 hours?
We want this probability"
At most 3 hours?
b) What is the probability that rainfall duration exceeds the mean value by more than 2 standard deviations?
What is the probability that it is less than the mean value by more than one standard deviation?
Step-by-step explanation:
Previous concepts
The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution". The probability density function is given by:
The cumulative distribution for this function is given by:
We know the value for the mean on this case we have that :
Solution to the problem
Part a
What is the probability that the duration of a particular rainfall event at this location is at least 2 hours?
We want this probability"
At most 3 hours?
Part b
What is the probability that rainfall duration exceeds the mean value by more than 2 standard deviations?
The variance for the esponential distribution is given by:![Var(X) =\frac{1}{\lambda^2}](/tpl/images/0512/0749/9af6b.png)
And the deviation would be:
And the mean is given by![Mean = 2.725](/tpl/images/0512/0749/f2555.png)
Two deviations correspond to 5.540, so we want this probability:
What is the probability that it is less than the mean value by more than one standard deviation?
For this case we want this probablity:
