Tri-county utilities, inc., supplies natural gas to customers in a three-county area. the company purchases natural gas from two companies: southern gas and northwest gas. demand forecasts for the coming winter season are as follows: hamilton county, 400 units; butler county, 200 units; and clermont county, 300 units. contracts to provide the following quantities have been written: southern gas, 500 units; and northwest gas, 400 units. distribution costs for the counties vary, depending upon the location of the suppliers. the distribution costs per unit (in thousands of dollars) are as follows: tofrom hamilton butler clermontsouthern gas 10 20 15northwest gas 12 15 18a) develop a network representation of this problem. b) develop a linear programming model that can be used to determine the plan that will minimize total distribution costs. c) describe the distribution plan and show the total distribution cost. d)recent residential and industrial growth in butler county has the potential for increasing demand by as much as 100 units. which supplier should tri-county contract with to supply the additional capacity?

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?
