Hello everyone! its me! I'm pretty sure I did these right but I need to make sure, the class average on the hws have been 70s, so i wonder what i got Directions: Some of the arguments in 7-18 are valid by universla modus ponens or universal modus tollens; others are invaldi and exhibit the converse or the inverse error State which are valid and which are invalid. Justify your answers. #14. If a complication of a computer porgram produces error messages, then the program is not correct. Compliation of this program does not produce error messages. .:. This program is correct. I said P(x) = compliation of a computer program produces error messages Q(x) = the program is not correct. So, [tex]\forall[/tex], if P(x) then Q(x) ~P(x) .:. ~Q(x) invalid, inverse error. #17. If an infintie series converges, then its temrs go to 0. The terms of the infinite series n/(n+1) do not go to 0. .:. THe infine series n/(n+1) does not converge. So i wrote: [tex]\forall[/tex] x, if P(x) then Q(x) ~Q(x) .:. ~P(x) Valid, Universal modus Tollens. Thanks!
