Please show step by step work to get the solutions. Thank you : )

The dial-up connection from your home router to your ISP's network has a capacity of 40 kbps. Your home has 4 computers, each of which is generating 3 packets/sec. Packet size is Poisson distributed with an average length of 250 bytes. Assuming the packet generation follows a Poisson process, compute: Utilization of the transmission line. [2 pt] Total number of packets in the queue system. [2 pt] Total queuing delay in the system. [2 pt] The dial-up connection from your home router to your ISP's network has a capacity of 40 kbps.
