For this case what you must do is to graph both lines. (See attached graph) and see where both are cut.
We note that both lines are cut at the point (2,5)
Therefore the solution for f (x) = g (x) is x = 2
answer
x = 2
We note that both lines are cut at the point (2,5)
Therefore the solution for f (x) = g (x) is x = 2
answer
x = 2
Answer:
(a) The standard deviation of your waiting time is 4.33 minutes.
(b) The probability that you will have to wait more than 2 standard deviations is 0.4227.
Step-by-step explanation:
Let <em>X</em> = the waiting time for the bus at the parking lot.
The random variable <em>X</em> is uniformly distributed with parameters <em>a</em> = 0 to <em>b</em> = 15.
The probability density function of <em>X</em> is given as follows:
(a)
The standard deviation of a Uniformly distributed random variable is given by:
Compute the standard deviation of the random variable <em>X</em> as follows:
Thus, the standard deviation of your waiting time is 4.33 minutes.
(b)
The value representing 2 standard deviations is:
Compute the value of P (X > 8.66) as follows:
Thus, the probability that you will have to wait more than 2 standard deviations is 0.4227.
