There has been an urge to change it for a while. There was an initial attempt to change the Maths syllabus back in 2014-2015, well before this one came into effect. You can see what they had proposed back then (Maths Ext2 in particular was originally intended to be far more jam-packed in...

Another reminder to please put subject specific threads to their respective subject forums

lol the recent HSC syllabus update was the first major change in 20 years...

Another thing to consider is that the empirical case fatality rates are inclusive of the effects of mitigation measures (e.g. hospital interventions, masks, vaccines, lockdowns). You cannot reliably extrapolate that this same empirical case fatality rate is also a true representation of the...

I don’t think controlling cases will matter anymore by then. The expectation is that the 70% fully vaccinated threshold would have been hit well before then to enable a reopening more broadly, regardless of case numbers.

I don't think the question is well written. If we want to be more technical about it, the problem lies in how you actually define a “square root” of a complex number which is a bit beyond the syllabus. Strictly speaking (i.e. in "pure maths" speak), a square root of a number a, is the solution...

I actually think that if lockdowns occurred before the age of social media there would be a lot more compliance. Social media has made it much easier for alternative voices to channel through to other people, not the other way around.

I have moved this to the Maths Advanced forum. For future reference, please post subject specific threads in subject specific forums. Thanks.

Find E(X) and E(X^2) (the probability weighted average of X and X^2 respectively), then use the fact that Var(X) = E(X^2) - [E(X)]^2

That's definitely not the "Sydney Olympic Stadium" lol (the actual name is Qudos Bank Arena, but generally most people refer to ANZ Stadium as the "Olympic Stadium" which is not even a mass vaccination venue). I got vaccinated there and and it looks nothing like that inside.

When the state governor bans schools from enforcing their own mask mandates...

For future reference, please post subject specific threads in their respective subject forums, not the general HSC forums. Thanks.

Whilst I agree that we cannot have lockdowns as a long term solution, I actually think that we are not yet at that boundary point between temporary measures vs sustained measures. We are still in the midst of grappling with short term issues and will be for a while yet, especially given under...

We have to be comfortable with the reality that there is just too much uncertainty. We cannot demand guarantees for something that is unpredictable. No one knows how the virus will behave over time, the best you can do is speculate what might happen. There is always the possibility that...

It will be interesting to see where Australia’s “critical mass” is in terms of vaccination rates - where everyone is vaccinated to the point where you’re just left with people who will outright refuse to get it.

Unfortunately, for the US it’s a choice between horrible options either way to get out of this hole that they dug themselves into. Either being stuck in this state of “forever war” or withdraw (which they inevitably have to do at some point it was just a matter of when). You’re kidding yourself...

Have you looked at all the previous HSC papers in the old syllabus? The vast majority of the new syllabus overlaps with the old syllabus so as long as you know what the relevant topics are, you can selectively look at questions from at least 20 years of past HSC (and trial) papers.

For me, the biggest turnoff about the US is how far everything is politicised and ideological. It is ridiculous how something as basic as say mask wearing or vaccinations can be made so partisan. At least here (and arguably in most other western democratic countries), most leaders across the...

You will always get your own external mark. Moderating has no influence on that at all.

Moderating only occurs on the internal marks. The gaps between the ranks are largely preserved in that step and it’s just a matter of shifting the position of the cohort relative to the state (which is informed by the external marks of the cohort). In your example, person B and C must have very...
