This is a much more effective way of learning. Students at this school can really pursue their interests. Most importantly‚ students at this

BUS216 Exam #2 Review – Discrete Distributions 1. The number of calls coming into a PBX has a mean of 120 calls per hour. What is the probability of no calls in a one-minute interval? .1353 2. A school is sending 18 children to a camp. If 15% of the children in the school are first graders‚ and the 18 children are selected at random from among all 6 grades at the school‚ find the mean and variance of the number of first graders chosen? The mean is 2.7‚ and the variance is 2.3. n

Reorder Point As a result to today’s uncertain economy‚ companies are searching for alternative ways to stay competitive. One wrong move of a company in doing their forecasting and inefficient inventory control‚ can lead to multiple product stock outs and back orders. This issue has caused sales loss as well as profit loss‚ which companies cannot afford to lose if they want to stay competitive. To resolve this issue‚ the companies are using inventory control model which is the ROP also known as

Determination of an Equilibrium Constant Abstract: In this experiment‚ two reactions were run to determine the molar absorptivity and the equilibrium constant of FeSCN2+. The main principles used in this lab are equilibrium‚ LeChatlier’s Principle‚ Beer’s Law and Spectrocopy. The first reaction was run to completion using LeChatier’s Principle and the second reaction was run to equilibrium. A spectrophotometer was used to measure absorbances. Using a graph of absorbance versus concentration
