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
Answer:
x = 0
Step-by-step explanation:simplified is 8x-5y=0
Answer:
To be Honest I kinda do know but I can solve the equation for you if that helps
Step-by-step explanation:
5x+15y-6 is the answer
first you will add all of them and then distribute
Remove parentheses
=3x-18+15y+6+2x+6
Group like terms
=3x+2x+15y-18+6+6
Add similar elements
=5x+15y-18+6+6
Finally Add/Subtract the numbers
=5x+15y-6
