1. Define each of the following terms: a period: a horizontal row of elements in the periodic table. b group: a vertical column of elements in the Periodic Table. Elements in a group have similar chemical properties. c noble gas: an inert or non-reactive element that is located in a group 0 (or 18) of the Periodic Table. d transition metal: metallic elements found in groups 3–12 that often have coloured compounds. e alkali metal: metallic elements that are extremely reactive. Alkali metals are

My lab results were similar to my hypothesis. My hypothesis was that the densest object would be the rubber stopper. In the lab results the densest object was the penny and the rubber stopper was second. My hypothesis was switched. My hypothesis was correct when I stated that the macaroni was the third densest object. My hypothesis was also correct for the dice‚ but the bead and the dice share the same density. So they are both the fourth densest item. I was wrong with my hypothesis when I placed

Question 1: To compute the standard deviation‚ it is used the EXCEL STDEV ( ) Function and the expected return is equal to the sum of return rates in 24 months divided by 24. Stock | Vanguard 500 | California REIT | Brown Group | Standard Deviation | 4.61% | 9.23% | 8.17% | Expected Return | 1.10% | -2.27% | -0.67% | Question 2: To compute the standard deviation in a portfolio‚ it follows the formula SD= ( ) 1/2

Probabilistic Inventory Models 1. CONTINUOUS REVIEW MODELS 1.1 "Probabilitized" EOQ Model Some practitioners have sought to adapt the deterministic EOQ model to reflect the probabilistic nature of demand by using an approximation that superimposes a constant buffer stock on the inventory level throughout the entire planning horizon. The size of the buffer is determined such that the probability of running out of stock during lead time (the period between placing and receiving an order) does

Should Merck license the compound? Merck would be responsible for 1) the approval of Davanrik 2) the manufacture of Danavrik 3) marketing of Danavrik Merck would pay LAB for 1) initial fee 2) royalty on all sales 3) make additional pymts as Danavrik completed each stage of approval process (3 Phases) Additional facts: approval process should take 7 years patent will cover 17 years (7 of approval process nad 10 yr period of exclusivity beginning in yr 7) 1 Assumptions: All Cash flows

Kater’s Pendulum Thomas Markovich and Kapil Chhabria Departments of Physics University of Houston Houston‚ TX 77204-5006 (Dated: December 9‚ 2010) We experimentally determined the local gravitational constant using Kater’s Pendulum to provide the authors with experience in data analysis. In this manuscript‚ we rigorously derive the relevant equations from first principles with the appropriate expressions for the experimental uncertainty. We found that by assuming the periods were equal we were

Joan Holtz CASE 5-3 JOAN HOLTZ (A)* (1) Electric utility bills. An electric utility company can estimate with reasonable certainty the expected revenue in a given period by taking into consideration some of the following: customer habits‚ average historical trends‚ demand and supply forecasts‚ and environmental changes. The electric utility industry effectively uses an insurance industry concept—the law of large numbers‚ to determine with certainty‚ expected revenue. The law of large numbers
