An insurance company determines that N, the number of claims received in a week, is a random variable with P(N=n)=12n+1, where n≥0. The company also determines that the number of claims received in a given week is independent of the number of claims received in any other week. Determine the probability that exactly seven claims will be received during a given two week period.

Quality control of the vinegar sample Vinegar is essentially a dilute solution of acetic acid in water. Labels show the percent of vinegar by weight. We are going to test that. Dispense 5.0 ml. of vinegar into a clean 250 ml. Erlenmeyer flask. • Add distilled water until 50 mL. is reached. Add 2 drops of phenolphthalein. trind y • Perform the titration procedure a minimum of 3 times using the sodium hydroxide solution you, standardized. More trials is better. volume of vinegar (a) final buret volare (w) di frital buret wure (me) 0.0001 122. Use the data tables from previous parts of the lab to construct your own data table for this part. Plan the data table before you start your trials. Calculations: 1. Show the calculation for two trials of the standardization of your sodium hydroxide solution. List the results of any more trials you performed. 2. Use the results above to calculate the average molarity of the NaOH solution 3. Show the calculation for two trials of your titration of the strong acid using your calculated average molarity of your sodium hydroxide solution. List the results of any more trials you performed. 4. Show the calculation for two trials of your titration of the vinegar using your calculated average molarity of your sodium hydroxide solution. List the results of any more trials you performed. After calculating each trial, find the average molarity of your vinegar. 5. Use dimensional analysis to convert the average molarity of the vinegar to a mass percent. The density of the vinegar solution is 1.005 g/ml. Does the vinegar meet the minimum requirement from your label!
