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

  5. math

    Why ??????

  7. Math

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

  8. 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

  9. Math

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

  10. Geometry

    The question makes no sense to me

  11. Math

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

  13. sned help

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

  14. Math

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

  15. Math

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

  16. 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

  17. 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.

  19. 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 "

  20. 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

  21. math

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

  22. 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.

  23. 8th grade math connexus

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

  25. 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

  26. 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

  27. 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

  28. mathmatics

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

  29. math

    NO, not all the angles are less tan 90 degrees

  31. 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

  32. math

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

  33. math

    4 > p + 2 p < 2

  34. math

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

  35. Math

    YEAAA!!!! The bot is right.

  37. math

    p+7>10 p > 3

  38. 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) ?

  39. math

    question makes no sense, neither does the answer

  40. math

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

  41. Math

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

  43. math

    no answer, no data given

  44. 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

  45. math

    see comment above

  46. math

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

  47. algebra

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

  49. 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

  50. math

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

  51. 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

  52. Math-Algebra

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

  53. Math-Algebra

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

  55. 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

  56. Further mathematics

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

  57. 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

  58. Math-Algebra

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

  59. 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
