Given:
Arrival rate, λ = 7 
Service rate, μ = 8
a) probability that no requests for assistance are in the system (system is idle). 
Let's first find p. 
a) ρ = λ/μ

Probability that the system is idle =
 1 - p
= 1 - 0.875
=0.125 
probability that no requests for assistance are in the system is 0.125
b) average number of requests that will be waiting for service will be given as:
 λ/(μ - λ) 
 
 
= 7
(c) Average time in minutes before service 
= λ/[μ(μ - λ)] 
 
 
= 0.875 hour
(d) average time at the reference desk in minutes. 
Average time in the system js given as: 1/(μ - λ) 

 = 1 hour 
(e) Probability that a new arrival has to wait for service will be:
 λ/μ =
 
 
= 0.875
 
        
             
        
        
        
First, subtract 14 from 153.80 to get the ticket prices alone. You would get 139.8
Then, since they’re buying 4 tickets, you divide 139.8 by four to get the individual ticket pricing,
meaning your final answer would be $34.95 
153.80=4x+14 ⬅️ y-int form if you need that to solve

Answer:
2 /10
Step-by-step explanation:
The portion of the book that weight 2 1/8
Total number of books = 10
Number of books that weight 2 1/8 = 2
Fraction of book that weigh 2 1/8 = number of books that weigh 2 1/8 / total number of books
Fraction = 2 / 10
