Suppose the total cost of producing $x$ units of some commodity is given by the cost function $C(x) = 0.003x^2 + 5x + 50$, where $x$ is the number of units produced, and $C(x)$ is the total cost, in dollars, to produce $x$ units. A) Find a simplified expression for the marginal cost function. (Be sure to use the proper variable in your answer.) The marginal cost function is B) What is the marginal cost when 350 units have been produced? The marginal cost is dollars per item. (Your answer may be negative.)

Predict the major products of the reaction in the drawing area below. Be sure to use dash and wedge bonds to show stereochemistry if it's important (for example to distinguish between two similar major products). HCI Click and drag to start drawing a structure. Draw the product of syn addition of Cl$_2$ across the double bond of the alkene in the drawing area below. Important! Be sure you use dash and wedge bonds to show the stereochemistry at any new chiral centers in the product. Note for advanced students: if the product exists as a pair of enantiomers, just draw either one of them. Cl$_2$ Click and drag to start drawing a structure. Predict the major products of the organic reaction. Be sure to use wedge and dash bonds to show the stereochemistry of the products when it's important, for example to distinguish between two different major products. 1. BH$_3$, THF Click and drag to start drawing a structure. 2. H$_2$O$_2$, NaOH

Texts: QUANTITATIVE TECHNIQUES: ASSIGN2 - QUESTION 22.1 a) Richfield offers 15 different courses in its curriculum. SABC has agreed to advertise on TV but only has space to advertise four courses each day. Calculate the number of possible groupings of four courses that Richfield can advertise on SABC given that the order in which the courses are selected is not important. [5] b) You just landed a new job as a project manager and your first task for the currently running project is to try and estimate the probability of completing the project on time when requirements change. You are also provided with historical data and it shows you that 75% of previous projects were all completed on time. The same data also shows that of those that were completed on time, 35% of them had requirement changes while those projects that were not completed on time, 85% of them had requirement changes. Calculate the probability of completing the project on time given that requirement changes occurred. [10] Note: Full marks will only be awarded where calculation steps are shown and are clear. You will receive 1 mark for each answer with no calculation steps. Probability answers should be interpreted using percentages! 2.2 a) For the below random variables, indicate the data type.

[5] 2.3 A scientist was trying to compare the relationship between some x-variable and some y-variable. It follows that the x-variable consists of the first 10 numbers of the Fibonacci Sequence excluding zero. The y-values are the first 10 odd numbers. Using your knowledge, research and the information given above find Pearson’s Correlation Coefficient. Interpret and explain the meaning of your answer. [5]
