Refer to Q14 above for the context. Which of the following outputs is obtained upon conducting the operation b*e?

Given the following set of points –  [(1,3), (4,7), (5, 2), (3,5), (8, 3), (2, 2)] and initial cluster centroids [(3, 3) and (5, 4)], what will be the new cluster centroids after the first iteration of the K-means clustering algorithm? The labeling of iterations is defined as follows: the initial centroids are provided to you, but you do not calculate them. iterations are labeled as follows- first iteration is the iteration that involves the calculation of the centroids first time after assigning the data points to the initial clusters; second iteration is the iteration that involves the calculation of the centroids second time after assigning the data points to the clusters calculated at the first iteration; In general, nth iteration is the iteration that involves the calculation of the centroids nth time after assigning the data points to the clusters calculated at the (n-1)th iteration.

Refer to Q10 above for the context. Let W be the weight matrix obtained from a dataframe df using PCA (principal component analysis). If a row of the weight matrix W corresponding to a row of df is [1, -½, 4], which of the following options correctly represents the row of df ?
