Simplify the following symbolic statements, leaving your answer in the standard symbolic form. Then, express your simplified statement in natural English.
I haven't done this one yet. You get to go first! :)
b) P is at least 7, but less than 12. c) x is greater than 5 and less than 7 d) x is greater than 6. We ignore the x > 4 statement, since the conjuction is true only when x > 6. e) This one is tricky. Y is less than 4, but y must also be between -3 and 3. The conjuction is true only when y is between -3 and 3. f) x is 0.
I don't know what is happening when I put my answers in for this question. I just copied them from a word document and entered them in again and got the same result as yesterday. b and f are correct, but c is wrong and d and e are missing. I'll type them in manually and see what happens. c) 5<x<7 d) x<4 e) -3<y<3
Apparently copying and pasting doesn't always work here. I was struggling with the math symbols and thought it was easier to put the answers into a word document and copy it.
The problem I have for d is: (x<4)^(x<6), and you seem to have the problem: (x>4)^(x>6)
If you are copying from Word, you will have problems. If you are copying from Notepad, you will not. HTML (a website) does not also read Word characters. (I've been waging battle with Word for about 20 years!)
b) 7≤ p< 12
ReplyDeletec) 5-3 or Y<3
f) x=0
b) P is at least 7, but less than 12.
ReplyDeletec) x is greater than 5 and less than 7
d) x is greater than 6. We ignore the x > 4 statement, since the conjuction is true only when x > 6.
e) This one is tricky. Y is less than 4, but y must also be between -3 and 3. The conjuction is true only when y is between -3 and 3.
f) x is 0.

ReplyDeleteI have the same answer as Margie for d: x<4.
