kk

OpenStudy (anonymous):

ok what if the question is this: If n is a prime number greater then 2, then n squared is an odd number. 9 squared is an odd number. what would be the conclusion?

jimthompson5910 (jim_thompson5910):

you can't use the law of detachment here

jimthompson5910 (jim_thompson5910):

if you changed "9 squared is an odd number" to something like "7 is a prime number", then it would work and your conclusion would be "7 squared is an odd number"

OpenStudy (anonymous):

so its not possible.

jimthompson5910 (jim_thompson5910):

no it's not, it's a very specific form

OpenStudy (anonymous):

is the law of syllogism the other way around? like if q then p?

jimthompson5910 (jim_thompson5910):

the law of syllogism is if p then q if q then r therefore if p then r

jimthompson5910 (jim_thompson5910):

so it's like a chain of events

jimthompson5910 (jim_thompson5910):

one link of the chain causes a ripple in another

OOOH ok so if the statement is: If an animal is a red wolf, then its sciemtific name is Canis rufus. If an animal is named canis rufus it is endangered. Conclusion: The red wolf is endangered?
