You are a data scientist and received the following principal components (PC-1 to PC-3) from a third party and expected to use it for a machine learning task. The supplier obtained these principal components after applying the PCA on a training dataset in order to reduce the dimensionality. The original training dataset was not shared with you to maintain the confidentiality. Somehow the principal components were corrupted and few values of the tables are missing now. Find out the values of x and y. Do not round off and show all the calculations. Direct answers or copy and paste from web/any tool/language will not be accepted. [5 Marks]
