Answer:
Part A: x = 4.
Part B: The answer normally would be x = 12, but since your question asked why it has no real solution, it is because the solution (x=12) does not make the equaion true. Why? Because the value given from the equation that should make the equation true does not relate the equation in itself; hence making it have no solution.
First place is a
Fifth place is b
Answer:
The answer is B) 0.57.
Step-by-step explanation:
In this problem we have to apply queueing theory.
It is a single server queueing problem.
The arrival rate is
and the service rate is
.
The proportion of time that the server is busy is now as the "server utilization"and can be calculated as:

where c is the number of server (in this case, one server).
