There are gays in here. I wonder why a sane man will register as a 'female' on a forum like this. Your sex is your identity.be real! |

hey guys, who could derive the moment generating funtion of hypergeometric distribution. note that it is discrete random variable. |

Karmanaut:i think i now see why that statistics lecturer skipped it. hypergeometric distribution has no M.G.F |
Re: Nairaland Mathematics Clinic by Nobody: 10:58am On Aug 29, 2015 |
lexiconkabir:Your lecturer told you to derive the MGF? |
Re: Nairaland Mathematics Clinic by Nobody: 11:01am On Aug 29, 2015 |
Karmanaut:actually he did not, but out of curiousity i wanted to, because he never asked us to derive that of normal distribution, and i derived it myself! |
Re: Nairaland Mathematics Clinic by Nobody: 11:07am On Aug 29, 2015 |
lexiconkabir:Ok. |
Re: Nairaland Mathematics Clinic by Nobody: 11:22am On Aug 29, 2015 |
Karmanaut:thanks! can you please integrate exponential raised to the power of 5x all divided by 5x? |
Re: Nairaland Mathematics Clinic by Nobody: 12:13pm On Aug 29, 2015 |
lexiconkabir: The answer is ... (Ei(5x))/5 + C Where Ei(x) is the Exponential Integral given as or the derivative of (e^x)/x. Cheers. |

Porthos:you see someone using a powerful terabyte computer (probably, Wolfram Alpha) to solve maths and you're asking whether to believe him. Who am I, abeg? I trust that computer more. Believe him, FFS! 1 Like |

Porthos:fact: The guy is good no doubt.............. But maybe you need to learn how to distinguish between problems solved with computer apps and those solved manually,as many seen here are solved with the aid of system software. Mathematics is now made easy with recent mth app. I would have posted some earlier, but that is like contributing to...............*you know the rest*........................... I may be posting guides/hints tho to solving some(if my hussle/sku decide to give me chance to). But sincerly it takes a mathbrain to effectively use and interprete results from these apps....................#backtosidelines |

Re: Nairaland Mathematics Clinic by Mayour11(m): 1:00pm On Sep 01, 2015 |
pls, help me look into this; 1) A boy of mass 40kg sits from the pivot of a bench while his 30kg friend sits on the other side. Calculate the distance of the two friends when the bench is at equilibrium. 2) A uniform beam is 12m long and has a mass of 50kg, and masses of 30kg and 40kg are suspended from its ends. At what point must the beam be supported so that it may rest horizontally? |

Mayour11:6.5, if my assumptions are correct

Mayour11:info nt complete.. Check again pls 2) A uniform beam is 12m long and has a mass of 50kg, and masses of 30kg and 40kg are suspended from its ends. At what point must the beam be supported so that it may rest horizontally?30(6+x) + 50x = 40(6-x); 120x = 60; x = 0.5 The answer is 0.5m to the midpoint.. =6+0.5 = 6.5m nB: sum of clockwise moment=sum of anticlockwise moment |
Re: Nairaland Mathematics Clinic by agentofchange1(m): 4:05pm On Sep 01, 2015 |
If a prime number and a[a-1!+1] is divisible by 2a.
Then a^a is ? |
Re: Nairaland Mathematics Clinic by Mayour11(m): 6:13pm On Sep 01, 2015 |
Seamione thanks very much, dejt4u thanks bro, but that was all the lecturer gave, maybe he's trying something fishy. 1 Like |
Re: Nairaland Mathematics Clinic by Mayour11(m): 6:24pm On Sep 01, 2015 |
Help me check this out 1) A uniform half-meter bar AB is balanced horizontally across a knife-edge placed 15cm from point A. A mass of 30kg is hang at the end of A. What is the weight of the bar? I got 450N, pls help me verify it. 2) A student want to compare the performance of an old spring-scale with a new one. He placed the scales at the end of a 2m long uniform horizontal bar of mass 4kg. If both scales are in good working condition, what should be their readings? Thanks in anticipation. |

Seamione: agentofchange1: Seamione is actually right and you are wrong. Your sample space is incorrect. This is not a combination problem, but a permutation problem. Selecting a multiple of 5 and an odd number from 1,2,4,5,6. Will give 4x3x1 + 4x3x1. To form a 3-digit number will give a space of 5x4x3 Probability = (2x4x3)/(5x4x3) = 2/5 1 Like |
