Baby maths guru in the house!!!! Pls who knows any shortcut for trig ratios or should I cram them? Cos the triangle method is long. |

rashywire: i knw I'll locate u guys, #shaking heads# ehn ehn, so dis is hw life b abi? Hweva, u guys re doing gr8 here. I'm nw here with u guys 2 learn, 2 solve n 2 help. @ omosive, my mentor always tell me d@ nothin is impossible nt until i found myself knwing basic maths n 4rm there I tank God, so u cn do it, a question may take u 5 days 2 tink, buh if u give it 2 another person 2 solve, d@ shows u dnt wnt 2 disturb ur brain. @ Ortarico, calculux, More PALMOIL 2 ur elbows. Lols. Letz drive mathematics plsThanks, I'm improving. Lamlad maths is all about thinking mathematically and I think I'm getting there but cramming tinzz is on my mind cos my exam is fast approaching. |

Omosivie,:Derz no need 2 cram dem like say sin30=1/2,sin60=sqrt3/2..e.t.c..All u need 2 knw is jst d "diagram" and frm der u can sot out d rest |

The probabailities that a man and his wife live for 80 years are 2/3 and 3/5 respectively. Find the probability that @ least one of them will live up to 80 years. A 2/15 B 3/15 C 7/15 D 13/15. Please solve and break it down for me. Thanks |
Re: How To Calculate Quickly And Correctly In Mathematics by MrCalculus(m): 2:49pm On Jul 13, 2013 |
@OMOSIVIE let d prob. dat d man leaves up 2 80yrs=P(M)=2/3 and d prob. dat e does nt=P'(M)=(1-2/3)=1/3. let d prob. dat a woman leaves up 2 80yrs b=P(W)=3/5 and dat she does nt=P'(W)=(1-3/5)=2/5 :(@ least 1 leaves up 2 80yrs)=[P(M)xP'(W)]+[P'(M)xP(W)] =[2/3x2/5]+[1/3x3/5] =4/15+3/15=7/12 1 Like |

Mr Calculus: @OMOSIVIEThanks, but wat if the question is: Find the probability that only one of them will live up to 80 years. |

Omosivie,:[Yeapy] it is i mr calculus am getin som temp dificulties postin i fink i made a mistake in d 1st calculatn o dat 1 was 4 only 1 leave up 2 80yrs @ least 1 means 1 and above P(@ least 1 leave up 2 80yrs)=[P(M)xP'(W)]+[P'(M)xP(W)]+[P(M)xP(W)] =[2/3x2/5]+[1/3x3/5]+[2/3x3/5] =4/15+3/15+6/15=13/15 1 Like |

Approximate 48.5 to the nearest whole number... |
Re: How To Calculate Quickly And Correctly In Mathematics by Ortarico(m): 5:22pm On Jul 20, 2013 |
Calculusf(x): I believe that this appro has to do with boundaries of a thing . Why not educate us on it like you did on 2go prof. |
Re: How To Calculate Quickly And Correctly In Mathematics by MrCalculus(m): 7:58pm On Jul 20, 2013 |
Calculu Approximate 48.5 to the nearest whole number...if u are to educate us biko educate us hear oooooo |

For approximation stuff...if we are to approximate to d.p(decimal places)...e.g 2.7253...to 3dp,since the fourth digit to the decimal is 3 and less than 5...therefore,it's neglected...so,it becomes.2.725...if,3.5555.is to be approximated to 2dp...,the third digit to the decimal is 5 but that 5 still has some numbers at the back...so,it's changed to 1 and added to the next one...then it becomes...3.56...let's now go to the main point,if 4.65 is to be approximated to 1dp...the second digit to the decimal is 5(and nothing at the back again)...then the number before the 5 is approximated to the nearest even number...which now become 4.6...but if 4.75 is to be approximated to 1dp or 2sf,then it will be 4.8... |
Re: How To Calculate Quickly And Correctly In Mathematics by Calculusfx: 11:17am On Jul 21, 2013 |
So,for the question 48.5 to the nearest whole number gives 48...that's all...let's use this analogy...find the class interval of 48.then it ranges from 47.5 to 48.5...so,anything in that is approximated to 48...it means 47.5 and 48.5 both have approximation of 48... |
