Answer:
A
Step-by-step explanation:
The volume of the cone is found using the volume formula for a cone
.
Substitute h=8 and r = 12.

So the volume is approximately 1,206 cubic cm.
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
AB- 3in.
BC- 5in.
CD- 7.2in.
sorry i don't really have an explanation I just looked at the picture and i guess imagined it in my head? lol sorry but here are the answers I hope that helps at least a little bit :))
Answer:20.25
Step-by-step explanation:
If you do 81 divided by 4
I think Im not sure
75 +10n = 15n
75 = 5n
15 = n
Therefore 15 classes
