Required information
Consider the following hypotheses:
"Randy works hard," f Randy works hard, then he is a dul boy," and "If Randy is a dul boy, then he will not get tho job"
imply the conclusion "Randy wil not get the job."
Using the predicates W(x) = "xworks hard", D (x) = "x is a dull boy", and J(x) = "x will get the job", defined on the set of all
objects, formalize the argument by breaking it down to the level of elementary argument forms. Do this by making a
suitable selection at each of the following steps.
Identify the hypotheses first. Then pick the conclusions that follow according a rule of inference and identify the rule of
Inference in parentheses.

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?
