Please? This is really important...

the first four are correct, so nice job on that so far

5 is correct
but 6 is not

- jim_thompson5910

same with 7, #7 is incorrect

- jim_thompson5910

8 is incorrect as well

- 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

10 is incorrect, you mixed up inverse and contrapositive

- jim_thompson5910

11 is correct

- jim_thompson5910

12 is correct

- jim_thompson5910

13 is correct

- jim_thompson5910

14 is correct

- jim_thompson5910

15 is correct

- LifeIsADangerousGame

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.

- jim_thompson5910

16 is a fallacy...which a lot of people mix up
16 is not a valid argument

- LifeIsADangerousGame

Alright, I fix that

- jim_thompson5910

#10 (this new one), you're looking for the inverse? converse? contrapositive?

- 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

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

19 is wrong

- jim_thompson5910

so is 20

- jim_thompson5910

21 is correct

- jim_thompson5910

22 is correct because the two aren't equivalent (having 4 legs and being a dog)

- jim_thompson5910

23 through 25 are all correct

- 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

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

It would be false.

- 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

ok now go back to the original statement
"A dog is an animal with four legs"
is that true or false?

- jim_thompson5910

you have them mixed up, that's why

- LifeIsADangerousGame

That is true

- 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

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

Right, but then the converse of it "If an animal is a dog, then it has four legs." would be true right?

- jim_thompson5910

yes it would be true, but again you have them mixed up

- 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

the converse would be "If an animal has four legs, then it is a dog" which is false

- LifeIsADangerousGame

But that's not one of my answers D:

- jim_thompson5910

what do you mean

- 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

well idk what to tell you, there's a serious typo or something is missing

- 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

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

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

17 is NOT A because "If an animal has four legs, then it is a dog" is NOT true

- 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

but flip it and it's definitely true because all dogs have 4 legs (assuming they didn't lose any)

- LifeIsADangerousGame

But in Question 18, I said that A is false which is correct, correct?

- jim_thompson5910

18 would be true

- jim_thompson5910

because the conditional "If an animal is a dog, then it has four legs." is true

- jim_thompson5910

so you can see how messing up one (#17) messes up the rest (#18 through #20)

- LifeIsADangerousGame

Oohh, I do get it. Yikes that would've been a huge mistake D:

- LifeIsADangerousGame

Thanks so much for explaining it all to me, I hope I didn't frustrate you or anything D:

- jim_thompson5910

you're fine lol

- LifeIsADangerousGame

Thanks again! I'll let you know what grade I get ^_^

- LifeIsADangerousGame

I got 44/50, 6, 19, and 20 were incorrect

- 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

hmm i knew something fishy was up with 17-20...there had to have been a typo

- 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

And 20 was wrong because 19 was wrong so I know 20 is supposed to be False.

- jim_thompson5910

yeah everything was dependent on 17
so if you got 17 wrong, then everything from 18 onto 20 was wrong

- LifeIsADangerousGame

Yea, but I got 17 right

- jim_thompson5910

true, so there has to be a typo in #19

- 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.

- jim_thompson5910

good idea
