Part A These following predicates, objects, and relations are for question 1, 2, and 3: :x is a doctor :x is a nurse :x has a private practice P(x) N(x) O(x) M(x) C(x) S(x,y) :x is famous :x has a cleaning service :x is y by profession : Sa'ad : Ahmad : Imron i : professional nurse : professional doctor 1. Translate this following English sentence into predicate logic formula: Because Sa'ad is a doctor but does not have a private practice, he is not famous.

Suppose that A E Mmxn(R) is a matrix of user ratings of various movies (on a scale of 1 to 5). Suppose we have computed the SVD of А, and decided to keep the 10 largest singular values as the most important determining factors for a user's choice of movie. Suppose also that a new user has joined the movie subscription service, and has rated some, but not all, of the movies. To predict how this new user will rate other movies (and thus, to determine which ones to recommend), all movies the user has not watched are assigned the average rating for that movie given by all users to form a new matrix A' E M(m+1)xn(R), and the rank-10 approximation of A' is computed from its SVD. The values in the approximation to A' are taken as the predicted ratings for the new user. Given this procedure, which of the following conclusions is most correct?
