G. a single server queue has exponential arrivals with a rate of 20 per hour. the service distribution is such that the mean number of customers that can be served is 24 per hour. the standard deviation is 2.0 minutes for the service distribution. obtain the steady mean number in the queue and also the mean waiting time in the queue. if the service distribution were exponential how would the standard deviation of the service times change? what would the steady state mean number in the queue and the waiting time in the queue be in this case?

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

Here are the answers to the ones that i could see.
