    I have no idea what to do here. lol Calculus, yeah?

    x by x =7 I would guess 3.5 but I will not count on that being right :)

    :salam2: the equation is not well given because i don't have that key so don't worry,anyway here's the solution
    x=-v7 or x=v7
    v as square root

    the square root of 7 is = 2.6457513110645907

    so as you said
    x= 2.6457513110645907
    or
    x= -2.6457513110645907

    If you just take the sqrt of 7 then Umm Ismael is right, correct :confused: Just asking because Umm Ismael already gave that answer.

    ذكرت كلمة البحار (أي المياه) في القرآن الكريم 32 مرة،

    وذكرت كلمة البر (أي اليابسة) في القرآن الكريم 13 مرة.

    فإذا جمعنا عدد كلمات البحار المذكورة في القرآن الكريم

    وعدد كلمات البر، فسنحصل على المجموع كالتالي: 45

    وإذا قمنا بصنع معادلة بسيطة كالتالي:

    ) مجموع كلمات البحر (تقسيم) مجموع كلمات البر والبحر (ضرب) %100

    ) مجموع كلمات البر (تقسيم) مجموع كلمات البر والبحر (ضرب) %100

    And if we compare those results to what science nowadays show?? ;)

    :wasalam: this equation shows 71.1% of water(sea) and 28.8 of land which explains the global warming,i guess.

    Asselemou Alaikum,

    i dont know if it explains the global warming, but i know that science proved the same number... :

    نحصل على هذا الناتج المُعجز الذي توصل له القرآن من 14 قرناً، فالعلم الحديث توصل إلى أن:

    * نسبة المياه على الكرة الأرضية = 71,11111111111 %

    * ونسبة اليابسة على الكرة الأرضية = 28,88888888889 %


    وإذا جمعنا العدد الأول مع العدد الثاني فإننا نحصل على الناتج = 100%،

    سبحان الله

    وهي مجموع نسبة الكرة الأرضية بالفعل،

    فما قولك بهذا الإعجاز ! هل هذه صدفة؟

    من علم محمد صلى الله عليه وسلم هذا الكلام كله؟

    من علم النبي الأمي في الأربعين من عمره هذا الكلام؟


    ولكني أقول لك: (وما ينطق عن الهوى، إن هو إلا وحيٌ يوحى، علمه شديد القوى) صدق الله العظيم

    فاسجد لربك شكراً لأنك من المسلمين،

    لأنك من حملة هذا الكتاب العظيم،

    وأنا أقول لك إن هذا بعض الإعجاز العددي في القرآن الكريم وليس الإعجاز كله،

    :)

    Alhamdu li Allah

    Salam

    Solution

    X=5
    how about X+3y=12...........equation 1
    4X+6y=40...........equation 2
    Solve the equations simultaneously and find the values of X and y

    :salam2:brother this's what i got as solution tell me if it's not correct insallah.
    x+3y=12
    4x+6y=40

    x+3y=12 means x=12-3y

    4(12-3y)+6y=40
    48-12y+6y=40
    -6y=-8 y=4/3

    now let's find x
    x=12-3y
    x=12-3(4/3)
    x=12-12/3
    x=36/3-12/3
    x=24/3 x=8
    :wasalam: hope i get it right anyway let me know inshallah brother.

    x=19.43548387
    y=14.11290323

    Next question......

    If you throw a dice 6 times, what's the chance that you'd get a six on:
    a: exactly one of the throws.
    b: one or more of the throws

    As-salamo'alaikum,

    1/6 is for throwing dice once.
    For further throwings if you want to have 6 in each throwing you have to (1/6)^x
    x=number of throwings
    If you want it to happen just for 1 time
    You have to have 5/6 5 times and 1/6 once so
    (5/6)^5 * 1/6...this is the probability of getting a six on exactly once...similarly we can find for other condition.

    Hope the probability of my answer being correct is 1!! InshALLAH..

    A Simple one

    Jack and Jill have two children. The probability that the first child is a girl, is 50%. The probability that the second child is a girl, is also 50%. Jack and Jill tell you that they have a daughter.

    What is the probability that their other child is also a girl?

    As-salamo'alaikum,

    The sample space is here the three possible combinations {B, G}, {G, B}, {G, G}.

    so the answer is 1/3..

    First the simpler one. The two events are not correlated to each other. So the probability of the other child being 50% remains valid, even if you already know, that one child is a daughter.

    Now the more difficult ones:
    (1). The probability of exactly 1 six in exactly one particular throw is (1/6)(5/6)^5. For the probability of exactly 1 six in any one of the throws you have it add it 6 times. That means the answer is: (5/6)^5.


    (2) The proabability of getting one or more sixes in the six dice experiments: (1/6)^6 times i = 0 S5 (5)^i. No calculator to get it more simplified.
