Answer:
1/6
Step-by-step explanation:
Let X = amount of time (in minutes) a postal clerk spends with his or her customer. The time is known to have an exponential distribution with the average amount of time
X is a continuous random variable since time is measured. It is given that μ = 6 years. To do any calculations, you must know m, the decay parameter.
m = 1/μ = 1/6
So the decay rate is 1/6
3.939x10^-6
That should be right.
Answer is B because what it is asking you to do is which ones are about 50% so you add the percents from the answers together and the one that isn't close to 50% Is the answer this is B because
32+29+13=74 this is the only one that is way to big if you add the others they are approximately 50%
Im going to guess you want a sinusoidal function. Its been a while but I can tell you most of it
(443-28)/2 is the amplitude
28 minutes is the period
40-28 is the horizontal shift
(443-28)/2+28 is the vertical shift
