QUESTION 1 (10 MARKS) CaC2 is a fuel in a furnace that uses oxygen for heat to produce calcium oxide and carbon dioxide at standard state. Calculate the cost of the scrap to be heated to 1200°C if for 1 kg of scrap the cost is R6.50. The heat required to raise the temperature of 1 kg scrap to 1200°C is 122056J. The total weight of calcium carbide to be used is 450 kg $\Delta H_{\text{Calcium carbide}} = -58270 \text{ J}$ $\Delta H_{\text{Calcium Oxide}} = -620140 \text{ J}$ $\Delta H_{\text{Carbon Dioxide}} = -385120 \text{ J}$ $\Delta H_{\text{Oxygen at 300K}} = -125000 \text{ J}$ $M_{\text{Calcium}} = 40 \text{ g/mol}$

What is the best case scenario for the ROC curve in terms of the Area Under the Curve (AUC)? A) The AUC is 0, indicating perfect separation. B) The AUC is 0.5, suggesting no discriminatory power. C) The AUC is close to 1, reflecting high discriminatory power, and the ROC curve “hugs” the upper left corner. D) The AUC is negative, indicating an inverse relationship between true positive rate and false positive rate. E) The AUC is greater than 1, signifying an exceptional discriminatory performance.

There are N people who vote in a certain election, and N itself is a random variable following a Poisson (1) distribution. Each voter votes for Roger with probability p and for Marjorie with probability 1-p, independently of all the other voters. Let X be the number of voters who vote for Roger. What is the distribution of X/N = n, the number of voters who vote for Roger, given that N=n voters have voted? b. Find the joint probability mass function, P(X=x, N=n). C. Find the (named) marginal PMF of X, P(X=x).
