Re: MATH2601 Linear Algebra/Group Theory Questions I don't know much about Graph Theory and Group Theory but are they two different topics? Or Different names but same subjects? I can't be bothered Googling it

+1 Also I would like past students who have sat General Maths in the past, that have done badly, done average, or done well to post their marks. Actually, if you PM your marks I'd accept that as well. (if you prefer to keep it a low profile).

Re: University Statistics Discussion Marathon what value of p did you get?

Re: University Statistics Discussion Marathon 50 % of the meals sold at Graylands Hospital contain rice. Answer the following question, keeping in mind that your answer must be a number between 0 and 1, i.e do not use percentages. Round off the final result to 2dp, but don't round numbers...

I've been misleading a particular student by telling him all along that 72% would be a Band 5. So I think personally a 72% would be slightly below the requirements for a Band 5. This is a kid that keeps saying to me "I want a band 6 " , "Im aiming for a high score"

I am curious to know what the Raw score band marks for General maths at a school would be, if you were to get Bands 1,2,3,4,5,6 for General mathematics. If anyone has a received a mark within these ranges , I would love to have a rough idea of how the mark breakdown is broken down. Based on...

Re: University Statistics Discussion Marathon Just want to confirm if this is the right answer :

Re: University Statistics Discussion Marathon Answer the following question, keeping in mind that your answer must be a number between 0 and 1, i.e do not use percentages. Round off the final results to 2d.p but dont round numbers during your calculation. Computer the probability that an...

My bad I misread your opening line.

Do you have any answers? So I can compare

Re: University Statistics Discussion Marathon Doing Statistics on a Good Friday is insanely awesome.

Re: University Statistics Discussion Marathon Anyway I had a go at. If someone could confirm that would be great.

Re: University Statistics Discussion Marathon The company Atherton uses a particular machine to fill 1 kg bags with sugar. The weight X of the machine processed bags follows a normal distribution with mean \mu and standard deviation \sigma =0.24. The machine mean weight can be set by the...

Re: University Statistics Discussion Marathon any idea how you would explain it? \sum_{i=1} ^n (x_i -1)^2 \sum_{i=1} ^n x_i ^2-2x_i+1 I don't see how you then can get to n-1

Re: University Statistics Discussion Marathon Damn I would have gone for 4th..........

Re: International Baccalaureate Maths Marathon Take back my comment about the school. Don't know much about the school personally except I have bumped across a couple of students from here. I hear a lot of complaints about students about how well a teacher can teach or can't teach a particular...

Re: International Baccalaureate Maths Marathon I'll take your word for it Integrand, I am still confused as to what non-negative means in this case. I thought the discriminant for sure was \triangle \geq 0 reading the question first up.

Re: International Baccalaureate Maths Marathon By the way this is a question from Newington, seems like the staff don't know how to teach the subject properly there. By setting the discriminant to less than equal to zero, we are trying to prove that there are no solutions for the real values...

Re: International Baccalaureate Maths Marathon \triangle=b^2-4ac (2p)^2-4(3)(q) \geq 0 4p^2-12q \geq 0 4p^2 \geq 12q p^2 \geq 3q This is the opposite direction of the inequality required in the proof. There has been a type in the whole question.
