Waiting line management: unit 11. The waiting line is a list of customers who remains waiting for getting certain goods or services from service center. Understanding waiting lines or queues and learning how to manage them is one of the most important areas in operation management. In organizations or in personal life‚ there are examples of processes which generates waiting lines or queues. Such waiting lines occur because the current services facility is insufficient to provide service at that

Cancel like terms: (y-3)(y-1) --------------- (y+3)(y+1) 5. = 1 / 16^3/4 = 1 / 2^3 = 1/8 6. Solve the equation: T = (3a + b)/2 for a. Multiply by 2: 2T = 3a+b Subtract b: 3a = 2T-b Divide by 3: a = (2T-b)/3 7. Factor completely: x³ + 1 Sum of cubes: (x+1)(x^2-x+1) For problems 8 – 11‚ solve each equation‚ inequality or system of equations.

reproduce. This comes in two forms. The first form of population growth is Exponential Population Growth. The second is Logistic Population Growth. Exponential population growth refers to when a population is not subject to any limiting factors‚ it will grow and expand exponentially even past the capacity of the environment to sustain. Rabbits are a good example of this form of population growth‚ “Thus‚ the exponential growth model explains how a few dozen rabbits can multiply into millions and

substance formed after a chemical reaction is called product. Chemical Equation: Representation of chemical reaction using symbols of substances is called chemical equation. Chemical Equation is a way to represent the chemical reaction in concise and informative way. Chemical equation can be divided into two types – Balanced Chemical Equation and Unbalanced Chemical Equation. Balanced Chemical Equation: A balanced chemical equation has number atoms of each element equal on both side. According to
