That moment when you notice a spelling mistake in your eco textbook: I seriously cannot read that line without getting distracted by the spelling mistake.

Re: 2015 HSC Economics Marathon Through the reduction of marginal income tax rates, Government revenue decreases. This decrease in revenue causes the Budget outcome to become a deficit or become less of a surplus, as there is less taxation revenue. Not sure why its 3 marks, since its a...

re: HSC Chemistry Marathon Archive All amphiprotic substances are amphoteric, but not all amphoteric substances are amphiprotic. For example, Al2O3 is amphoteric but it doesn't contain a hydrogen atom to be classified as amphiprotic Proton transfer reactions are known as neutralisation...

re: HSC Chemistry Marathon Archive Its just: Amphiprotic: Substances that can either donate or accept a 'proton' Amphoteric: Substances that can react with both acids and bases.

re: HSC Chemistry Marathon Archive Its Amphoteric first of all. Also all amphoteric substances don't have to be oxides, amphiprotic substances such as Hydrogen Carbonate (HCO3-) are also amphoteric as well, because by definition, amphoteric substances are substances that can react with both...

Those are some solid ranks, congrats!

Re: 2015 HSC Economics Marathon Well she was just clarifying about the impacts a change in the cash rate will have in terms of foreign investment.

Re: 2015 HSC Economics Marathon Well not really, if the question asked about exchange rates, you would need to talk about that, but it will be meaningless in the context of stimulating economic growth.

Will you be in attendance?

Re: 2015 permutation X2 marathon To form the groups of course, but when you put them into distinct rooms, having 4 people in room A and having 4 people in room B, and having them switch are two different arrangements, as 4 that were initially in A are now in B, and vice versa.

Re: 2015 permutation X2 marathon No the reason why I divided by 2! for that question was because I assumed the tables were identical. However in this question, the rooms are distinct, so you don't divide.

Re: 2015 permutation X2 marathon I don't think you should divide by 2! because they are distinct rooms labelled A, B, and C

Well they obviously would round it. So with the scenario with Bob and John, their internal marks will be 98, because the average would be 97.5. However when there are larger mark gaps, that's when it matters. I know that BOSTES said first internal person gets the highest external mark, there is...

No apparently its the average. That's what I initially thought, but according to sources, they take the average. Im not sure if its the average of the top 2 highest marks, or the average of the two people who are tieing, but it isn't as simple as both of them taking the highest external mark.

From what I hear, 4U maths are Ruse is very competitive (apparently their cohort average is 90+), so there would undoubtedly be several people on the same whole and maybe decimal mark, so what happens there then. Apparently there is around 100 students in 4u at Ruse, and they are all...
