The thing that is true about -5 and 5 is the answer is zero.
If you were to add the two numbers you would get 2 1/2 so the answer would be 2 1/2 hours altogether.
Answer:
9 and 10
Step-by-step explanation:
Answer:
The mean is 11.5 minutes and the standard deviation is of 6.64 minutes
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The mean is:
The standard deviation is:
Arrival time of 9:18 am and a late arrival time of 9:41 am.
9:41 is 23 minutes from 9:18. So the time is uniformily distributed between 0 and 23 minutes, so a = 0, b = 23.
Mean:
Standard deviation:
The mean is 11.5 minutes and the standard deviation is of 6.64 minutes
75%.
3/4 is .75. Drag the decimal to the right two times and it is 75%.
