Answer:

And using the cdf we got:

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:

And 0 for other case. Let X the random variable that represent the random variable of interest and we know that the distribution is given by:

We know the variance on this case given by :

So then the deviation is given by:

And if we solve for
we got:

The cumulative distribution function for the exponential distribution is given by:

Solution to the problem
And for this case we want to find this probability:

And using the cdf we got:

Answer:
Its A
Step-by-step explanation:
The answer is A, because the dot means it cant be 11, which is what the question is asking. Hope this helps!
Answer:
75.99
Step-by-step explanation:
Answer:
C) The variable x represents the independent variable.
Step-by-step explanation:
The given function is
.
g(x) is NOT the multiplication of g and x because g is a function of x.
is the input of the function.
is the output of the function.
The variable
is called the independent variable because we plug in values of x to find g.
The variable g represents the output of the function NOT the input.
The correct choice is C
Maybe d. but u should probably wait for another answer
