## Questions

1. ### What is going on?

I counted 21 postings in the last hour titled "public finance" by the same "student" They are not really questions, simply statements like "Reasons for market failure", and the AI then gives some canned reply. It looks like The AI is

2. ### Just stop it with the creation of all those silly round-off questions.

They have been appearing for days now and are just produced by the AI. Surely the bot doesn't need all those cases so it can "learn" how to do them. There are simple rules that can be

1. ## math

Simple arithmetic Mr. bot slope = (-11+9)/(6-7) = -2/-1 = +2

2. ## math

NO, it isn't , Mr bot √(3-6x) needs 3 - 6x ≥ 0 -6x ≥ -3 x ≤ 1/2

3. ## math

Did you really think that the bot could handle this ??? Of course not! |1/2 - x/3| = 5/6 case1 1/2 - x/3 = 5/6 -x/3 = 5/6 - 1/2 -x/3 = 1/3 x = -1 case2: -1/2 + x/3 = 5/6 x/3 = 4/3 x = 4 so x = -1 or x = 4

4. ## math

As expected, the bot screwed it up again. 1-|3p+1|=-3 -|3p+1| = -4 |3p + 1| = 4 3p + 1 = 4 OR -3p - 1 = 4 3p = 3 OR -3p = 5 p = 1 or p = -5/3

Why ??????

6. ## Math

total marbles : red marbles = 34 : 8 = 17 : 4

7. ## MATHH HELP yall

This new bot answering AI is wrong for many simple math problems. 8 x 19 using the distributive property = 8(10 + 9) = 80 + 72 = 152 one of the choices given is 8(19) = 8(20 - 1) = 8x20 - 8x1 = 160 - 8 = 152 so from your choices it would be (8x20)-(8x1) as

8. ## Math

Wrong answer by the bot. price after discount = 65(.60) = 39.00 after 5% tax added = 39(1.05) = 40.95

9. ## Geometry

The question makes no sense to me

10. ## Math

Weird!!! since the box is 14 1/2 by 14 1/2, and the diameter of the pizza is 14, it will fit.

11. ## sned help

Mr. Bot !!! please learn basic geometry ... complementary angles add up to 90°, so if one is 85°, the other is 5°

12. ## Math

Totally absurd answer by the bot I did this one correctly above this one.

13. ## Math

And the bot messes up again, this time in simple arithmetic 24(15) - 11(10) = 250

14. ## Math

OMG!!!! Students, don't trust this bot, in math it makes many mistakes, even for very simple questions like this 2l + 2w = 2(28) + 2(16) = 56 + 32 = 88 , not 76

15. ## Mathimatical

or b = 36 or b = 204 or ... any b = any prime times 12 the GCF of (24,48) would be 24, so the bot is wrong again.

16. ## math

The mesher of a circle ???? that's a new one, and of course the AI went right along with it, lol it was dumb enough to even call the radius of a circle " ratio r "

17. ## math

The bot is WRONG AGAIN I will assume you meant : f(x) = x^3-2x-1 f(-2) = (-2)^3 - 2(-2) - 1 = -8 + 4 - 1 = -5

18. ## math

none that I can see 0.1257486 = 1257486/10000000 , which is rational

19. ## Math

How many times does this same very simple equation get posted?? 2(x + 8)= 2x + 8 2x + 16 = 2x + 8 16 = 8 ???? , false statement, so there is not solution. Of course the bot got it wrong again.

20. ## 8th grade math connexus

WRONG AGAIN!!!! the bot did 15P3 15C3 = 15!/(3!12!) = 455

21. ## 8th grade math connexus

That answer by the bot is wrong of course!!!! Prob(1) = 5/18 so there are 17 left prob(10) = 6/17 prob(1, then 10) = (5/18)(6/17) = 5/51 = appr .098

22. ## HighSchool Mathmetics

First of all, the AI messed up again, its answer makes no sense. Secondly, please type normally. I assume you mean | 9-8x | = 2x + 3 first condition : 2x + 3 ≥ 0 -----? x ≥ -3/2 case1 : 9 - 8x = 2x + 3 -10x = -6 x = 6/10 = 3/5 , which is within our

23. ## Mathematics

Wrong answer by the bot!!! d : s = 3x : 4x 3x+4x = 5,720,000 7x = 5,720,000 x = 5,720,000/7 = 817,142.857 daughter gets 3x or 2,451,428.43 son gets 4x or 3,268,571.43 notice: 2451428.42 : 3268571.43 = .749999.. = .75 = 3 : 4

24. ## mathmatics

assuming you meant: (4 × 10^19)(9 × 10^-5) = 36×10^14 = 3.6 × 10^15

25. ## math

NO, not all the angles are less tan 90 degrees

26. ## Math

I did this further up, but with the illogical method of time spot, I can't find it total cost = 44*30 = 1320 for 20 people, cost per person = 1320/20 = 66

27. ## math

1 = 100/100 = 100% 4 = 400%

28. ## math

4 > p + 2 p < 2

29. ## math

finish it Mr. bot .... 4>p+2 2 > p p < 2

30. ## Math

YEAAA!!!! The bot is right.

p+7>10 p > 3

32. ## Math

Silly answer!!! y = 1/x has no y-intercept , nor an x-intercept also did you mean y = 5/x + 6 or y = 5/(x+6) ?

33. ## math

question makes no sense, neither does the answer

34. ## math

NOPE!!!! p - 2 < 10 p < 12

35. ## Math

The bot messes up as usual !!!!! cost of trip = 30*44 = 1320 cost per person if 20 go = 1320/20 = 66

37. ## Math

totally useless to just state an answer, Mr bot, especially if it is WRONG original ---- x after radio, amount left = x-48 after gift for friends, amount left = (5/8)(x-48) after putting 1/3 of that into charity, amount left = (2/3)(5/8)(x-48) but this is

38. ## math

see comment above

39. ## math

No idea what that column of symbols is. Type it in a normal way

40. ## algebra

if you meant: a(n) = -3(2n) + 1 then a(6) = -3(12) + 1 = -35 retype with more clarity

41. ## Mathematics.

Wrong again Mr. bot 1/3 - 1/x = 1/x - 1/2 1/3 + 1/2 = 2/x 5/6 = 2/x 5x = 12 x = 12/5 you must mean: (2- x)/ (x-3) =2/3 2x - 6 = 6 - 3x 5x = 12 x = 12/5

42. ## math

HUHHH?????? Come on Mr. bot !!! The complement of 50 is 40 degrees the supplement of 50 is 130

43. ## Mathematics

The bot messes up near the end, can't add fractions ... my way: 2/3 (x + 5) = 1/4 (5x - 3) times 12 8(x+5) = 3(5x-3) 8x + 40 = 15x - 9 49 = 7x x = 7

44. ## Math-Algebra

sorry Mr. bot but the answer is wrong!!!! 2(x + 8)= 2x + 8 2x + 16 = 2x + 8 16 = 8 ???? no solution possible

45. ## Math-Algebra

A better and correct way ..... 4x + 8 - 2x = 2x + 6 - 2 - x 2x + 8 = x + 4 x = - 4

46. ## Math-Algebra

Looks like more gobble-de-goup by the bot 5x − 12 − 6x = −10x + 7 − 1 -x - 12 = -10x + 6 9x = 18 x = 2

47. ## Further mathematics

Not enough information, question can't be answered e.g. how many had both measles and mumps ??

48. ## Math-Algebra

Another botched solution by the bot. Made up its own question and then couldn't solve it, lol Its instructions make absolutely no sense. 3x - 5 = 4x + 4 3x - 4x = 4 + 5 -x = 9 x = -9

49. ## Math-Algebra

LOL, looks like the bot is now cheating. It copied my solution, after the same question was posted about 12 postings ago.

50. ## Math-Algebra

Much ado about nothing by the bot .... (also the bot is wrong) 2x - 5 = 3(4x + 5) 2x - 5 = 12x + 15 -10x = 20 x = -2
