Q1. A lawyer bills her clients $250 per hour of service. If a client's case requires 47 hours to complete, use proportion to calculate how much the client will owe the lawyer (excluding tax).
Q2. A new virus is released on the internet; the administrator of a department's Local Area Network ( LAN) is given five minutes by a manager to estimate the impact. The administrator samples 12 of the PC's connected to the LAN, and finds that 7 are infected; use proportion to estimate the number of infected PC's if there are a total of 117 PC's connected to the LAN.
Q3. An administrator of a popular web site is told that a new server can handle 11,000 "hits" (users accessing the site) per second. The website currently experiences a peak demand of about 85,000 hits per second; but every month, the peak demand increases by 3500 hits per second. Use a proportion equation to determine how many new servers the administrator should buy to address expected traffic for the site.
Provide complete and step by step solution for the question and show calculations and use formulas.
