5 is correct but 6 is not

same with 7, #7 is incorrect
jim_thompson5910
  • jim_thompson5910
8 is incorrect as well
jim_thompson5910
  • jim_thompson5910
9 is incorrect too I think you mixed up the terms converse and inverse
LifeIsADangerousGame

Mmk, let me go back and do them. Thanks for checking them :D don't let me stop you xD
jim_thompson5910
  • jim_thompson5910
10 is incorrect, you mixed up inverse and contrapositive
jim_thompson5910
  • jim_thompson5910
11 is correct
jim_thompson5910
  • jim_thompson5910
12 is correct
jim_thompson5910

13 is correct
jim_thompson5910
  • jim_thompson5910
14 is correct

  • jim_thompson5910
15 is correct

For 10, my teacher corrected it because there was a mistake (all the answers are wrong). 10. If a shape is a rectangle then it has 4 right angles. A If a shape is not a rectangle, then it does not have 4 right angles. TRUE B If a shape is not a rectangle, then it does not have 4 right angles, FALSE C If a shape does not have 4 right angles, then it is not a rectangle, TRUE D If a shape has does not have 4 right angles, then it is not a rectangle, FALSE It's that instead and I choose C.

16 is a fallacy...which a lot of people mix up 16 is not a valid argument
LifeIsADangerousGame
  • LifeIsADangerousGame
Alright, I fix that
jim_thompson5910
  • jim_thompson5910
#10 (this new one), you're looking for the inverse? converse? contrapositive?
jim_thompson5910
  • jim_thompson5910
17 is incorrect (it's definitely not true because if an animal had 4 legs, then it could easily be a cow, so that's false...but the original statement is true)
jim_thompson5910
  • jim_thompson5910
18 is incorrect because it depends on 17 so if you got 17 wrong, then there's a very good chance you'll get 18 wrong
jim_thompson5910
  • jim_thompson5910
19 is wrong
jim_thompson5910
  • jim_thompson5910
so is 20
jim_thompson5910
  • jim_thompson5910
21 is correct
jim_thompson5910
  • jim_thompson5910
22 is correct because the two aren't equivalent (having 4 legs and being a dog)
jim_thompson5910
  • jim_thompson5910
23 through 25 are all correct
LifeIsADangerousGame
  • LifeIsADangerousGame
For number 10, I'm looking for the contrapositive. Why is 17 incorrect? I made the sentence into a conditional statement and then in 18 I said that the conditional statement was false.
jim_thompson5910

10. If a shape is a rectangle then it has 4 right angles. A If a shape is not a rectangle, then it does not have 4 right angles. TRUE B If a shape is not a rectangle, then it does not have 4 right angles, FALSE C If a shape does not have 4 right angles, then it is not a rectangle, TRUE D If a shape has does not have 4 right angles, then it is not a rectangle, FALSE C is correct for this one if you're looking for the contrapositive
LifeIsADangerousGame

Mmk, also what is wrong with 19 and 20?
jim_thompson5910
  • jim_thompson5910
think about it if I told you that "If an animal has four legs, then it is a dog" would what I'm saying be true or false?
LifeIsADangerousGame
  • LifeIsADangerousGame
It would be false.
LifeIsADangerousGame
  • LifeIsADangerousGame
But the one I chose says that: "If an animal is a dog, then it has four legs." And I said that (in Q 20) that that was true.
jim_thompson5910
  • jim_thompson5910
ok now go back to the original statement "A dog is an animal with four legs" is that true or false?
jim_thompson5910
  • jim_thompson5910
you have them mixed up, that's why
LifeIsADangerousGame
  • LifeIsADangerousGame
That is true
jim_thompson5910
  • jim_thompson5910
"A dog is an animal with four legs" is true but you said that the above translates to "If an animal has four legs, then it is a dog" which is false (a cat has four legs is a counter-example)
jim_thompson5910
  • jim_thompson5910
so the two statements "A dog is an animal with four legs" and "If an animal has four legs, then it is a dog" are logically not equivalent
LifeIsADangerousGame
  • LifeIsADangerousGame
Right, but then the converse of it "If an animal is a dog, then it has four legs." would be true right?
jim_thompson5910
  • jim_thompson5910
yes it would be true, but again you have them mixed up
jim_thompson5910
  • jim_thompson5910
"A dog is an animal with four legs" translates to "If an animal is a dog, then it has four legs." both of which are true statments
jim_thompson5910
  • jim_thompson5910
the converse would be "If an animal has four legs, then it is a dog" which is false
LifeIsADangerousGame
  • LifeIsADangerousGame
But that's not one of my answers D:
jim_thompson5910
  • jim_thompson5910
what do you mean
LifeIsADangerousGame
  • LifeIsADangerousGame
19. What is the converse of the statement? A If an animal is not a dog, then it does not have four legs B If an animal has four legs, then it is not a dog C If an animal does not have four legs, then it is not a dog D If an animal is a dog, then it has four legs. If an animal has four legs, then it is a dog isn't in there so the only one that is actually a conversed conditional statement would be D which is true
jim_thompson5910
  • jim_thompson5910
well idk what to tell you, there's a serious typo or something is missing
jim_thompson5910
  • jim_thompson5910
17 should be C 18 should be true 19 should be "If an animal has four legs, then it is a dog"
LifeIsADangerousGame
  • LifeIsADangerousGame
Wait, why is 17 C? I know it's not B or D because those aren't conditional statements, but why would it be C?
jim_thompson5910
  • jim_thompson5910
because "A dog is an animal with four legs" and "If an animal is a dog, then it has four legs." are both true statements
jim_thompson5910
  • jim_thompson5910
17 is NOT A because "If an animal has four legs, then it is a dog" is NOT true
jim_thompson5910
  • jim_thompson5910
"If an animal has four legs, then it is a dog" is false because a cat has four legs, but it's not a dog
jim_thompson5910
  • jim_thompson5910
but flip it and it's definitely true because all dogs have 4 legs (assuming they didn't lose any)
LifeIsADangerousGame
  • LifeIsADangerousGame
But in Question 18, I said that A is false which is correct, correct?
jim_thompson5910
  • jim_thompson5910
18 would be true
jim_thompson5910
  • jim_thompson5910
because the conditional "If an animal is a dog, then it has four legs." is true
jim_thompson5910
  • jim_thompson5910
so you can see how messing up one (#17) messes up the rest (#18 through #20)
LifeIsADangerousGame
  • LifeIsADangerousGame
Oohh, I do get it. Yikes that would've been a huge mistake D:
LifeIsADangerousGame
  • LifeIsADangerousGame
Thanks so much for explaining it all to me, I hope I didn't frustrate you or anything D:
jim_thompson5910
  • jim_thompson5910
you're fine lol
LifeIsADangerousGame
  • LifeIsADangerousGame
Thanks again! I'll let you know what grade I get ^_^
LifeIsADangerousGame
  • LifeIsADangerousGame
I got 44/50, 6, 19, and 20 were incorrect
LifeIsADangerousGame
  • LifeIsADangerousGame
For each statement below (#’s 6-9) write the converse of the statement and determine if the converse is true or false. 6. If a shape is a rectangle then it is a parallelogram. A If a shape is not a rectangle, then it is not a parallelogram TRUE B If a shape is not a rectangle, then it is not a parallelogram, FALSE C If a shape is a parallelogram, then it is a rectangle, TRUE D If a shape is a parallelogram then it is a rectangle, FALSE I think #6 should've been D instead. Because a square is a rectangle ( I think), but a rectangle is not a square.
jim_thompson5910
  • jim_thompson5910
hmm i knew something fishy was up with 17-20...there had to have been a typo
LifeIsADangerousGame
  • LifeIsADangerousGame
It is kinda weird, I'm going to have to talk to my teacher during office hours. #19 was 19. What is the converse of the statement? A If an animal is not a dog, then it does not have four legs B If an animal has four legs, then it is not a dog C If an animal does not have four legs, then it is not a dog D If an animal is a dog, then it has four legs. I chose D for 19 forgetting that I had change my answer for 17 (which made it so that they were the same statement and not conversed). But none of the other answers are correctly conversed..
LifeIsADangerousGame
  • LifeIsADangerousGame
And 20 was wrong because 19 was wrong so I know 20 is supposed to be False.
jim_thompson5910
  • jim_thompson5910
yeah everything was dependent on 17 so if you got 17 wrong, then everything from 18 onto 20 was wrong
LifeIsADangerousGame
  • LifeIsADangerousGame
Yea, but I got 17 right
jim_thompson5910
  • jim_thompson5910
true, so there has to be a typo in #19
LifeIsADangerousGame
  • LifeIsADangerousGame
Yea, she made a typo in #10 so it's likely. Thanks a whole bunch, I would've gotten a lot worse than 44/50 if you hadn't of checked it. I'll have to ask her about it after class.
