Experiment 41: 4-Methylcyclohexene Introduction: This experiment was a study of protonating a cyclo-alcohol to become a cyclo-ene. In this case 4-methylcyclohexanol was protonated using phosphoric acid to become 4-methylcyclohexene. This demonstrates the loss of an alcohol group by protonation‚ the loss of a proton from the cyclohexane to form an alkene through elimination. This also demonstrates Le Chatelier’s principle‚ by using distillation to remove the product as it is formed the equilibrium

OPIM Assignment 4 1. Cu = 24-11 = $13 Co = 11-7 = $4 Critical ratio = 13/(13+4) = 0.7647 μ = 30‚000 σ = 10‚000 Using normal distribution function (=norminv(0.7647‚30000‚10000))‚ the optimum order quantity is 37‚216 jerseys to maximize profit. 2. Quantity = 32‚000 First‚ we normalize the order quantity to find the z-statistic z=Q-μσ=32‚000-25‚00010‚000=0.7 We then look up the standard normal loss function. The expected lost sale is given by. Lz=0.1429 Therefore‚ the expected lost

Lab 4 Histology Name AL List the four types of tissue found in the human body and give an example of each. 1. Epithelial 2. Connective 3. Muscular 4. Nervous Epithelial tissue What are the characteristics of epithelial tissue? it never has contact with another cell‚ it always has a free surface. They contain no blood vessels (avascular) and depend on underlying tissues for needed nutrients and oxygen sources to maintain homeostasis. it is usually very thin for this reason

(d) An approximate 95% con…dence interval for the number of defaults for the portfop p p(1 p)=n‚ or equivalently np 1:96 np(1 p). lio is given by: np 1:96 n Plugging in p = :119‚ and n = 50‚ we get a con…dence interval of 5:95 4:49‚ or [1:46; 10:44]. This suggests we are approximately 95% con…dent that we will see between 2 and 10 defaults in our portfolio. (e) The Binomial distribution is great for independent trials like ‡ ipping a fair coin.
