2 NO$_2$(g) $\rightleftharpoons$ N$_2$O$_4$(g) dark brown colorless The dimerization of NO$_2$(g), an exothermic process, is represented by the equation above. A mixture of NO$_2$(g) and N$_2$O$_4$(g) is at equilibrium in a rigid reaction vessel. If the temperature of the mixture is decreased, then A [NO$_2$] will increase and the mixture will turn a darker brown B [N$_2$O$_4$] will increase and the mixture will turn a lighter brown C [N$_2$O$_4$] will decrease and the mixture will turn a lighter brown D no change will be observed

1) Determine the following summation in terms of n: $\sum_{i=1}^{2^n} (i^2 - i)$. (Note: Please express your answer in the form $\frac{2^a(2^b - 1)}{c}$, where a and b are functions in terms of n and c is an integer.) 2) Determine the following infinite summation: $\sum_{i=0}^{\infty} (2i + 1)(\frac{1}{3})^i$.

(a) [6 MARKS] Six students leave their six different bikes safely with a disorganised bike valet while they sit their discrete maths exam. (i) In how many ways can the six bikes be returned to the students? (ii) In how many ways can the six bikes be returned to the students, so that none of them gets their own bike back? (iii) How many ways can their bikes be returned to them, so that exactly one of them gets their own bike back? (b) [7 MARKS] Let G be a connected planar graph. (i) Starting with the path $P_2$, justify Euler's formula that $v + e - f = 2$. (ii) If G has at least 3 vertices, deduce that $e \le 3v - 6$. (iii) Hence, or otherwise, prove that $K_5$ is nonplanar.

Can someone please show me how to do this on Weka? For some reason, when I do it, I get the same accuracy rate, especially for the 0.02 which gives me 100%. And even when I change the random seeds, I am not sure what is wrong. So if I can get a step-by-step guide for the first two training set sizes, that would be great. Measure the impact of training set size on the accuracy and the size of the learned tree (no pruning, so use option -U) and use 60% of the data for testing. Consider training set sizes in the range of 0-40% (including at least the values 0.02, 0.1, 0.2, 0.3, and 0.4 for the training fractions). Because of the high variance due to random splits, repeat the experiment with ten different random seeds for each training set size. Then report the mean, maximum, and minimum accuracies at each training set size. Turn in two plots, showing how accuracy varies with training set size.
