Some of you may have seen that the Standard 2 paper was in this post: https://community.boredofstudies.org/threads/advanced-maths-predictions.401530/#post-7440329

But now there are solutions as well. They are attached here. They are by "teacher".

I think they should have mentioned positive correlation in Q35.

Some were common with Advanced and if you look at the solutions previously posted for the Advanced paper Q24 by 2xq, John Drake and romeo you see they all mentioned positive correlation

The Standard 1 and 2 papers are at https://www.educationstandards.nsw..../2022/mathematics-standard-2022-hsc-exam-pack

I haven't seen any Standard 1 solutions yet but those solutions will eventually go up at https://www.itute.com/download-free-vce-maths-resources/free-maths-exams/ but they are not up yet.

Here's another version. Error fixed.

Here's another version.

Thanks. It's good to have alternative versions of solutions.

Having said that though there seems to be a discrepancy in solutions to 27b

teacher solutions:



pc solutions


EDIT: This discrepancy has now been fixed. Go back to post#4 at https://community.boredofstudies.org/threads/standard-maths.401643/#post-7440848 and re-download for corrected version.

I think it's 4 years.

I think it's 4 years.

Yes. I think pc misunderstood the question. The question didn't say equate the two formulae and solve for n. It said when will the value of the machine be equal to the salvage value found in part (a) (ii) using the straight-line method.

You don't have to use the method that teacher did.

You can use an equation.

But if you use an equation it looks like this:



When you solve this equation you get n=4.

 

[PC]

Yes. I think pc misunderstood the question. It said when will the value of the machine be equal to the salvage value found in part (a) (ii) using the straight-line method.

Quite right. No I just rushed my work. I think my brain changed "found" to "used".

So are you going to upload a corrected version? I noticed you took it down.

EDIT: Ah. I see you uploaded a corrected version

Official paper is up now: https://www.educationstandards.nsw..../2022/mathematics-standard-2022-hsc-exam-pack and it contains both Standard 1 and Standard 2

 

[tywebb]

Matrix Education Standard 2 solutions are up: https://www.matrix.edu.au/2022-hsc-maths-std-2-exam-paper-solutions/

They obviously got the date wrong:


I'm sure they will fix that soon.

Here are the itute solutions for Standard 2: https://www.itute.com/wp-content/uploads/2022-NSW-ESA-Mathematics-Standard-2-Solutions.pdf

and for what I believe to be the first time online, the solutions to the Standard 1 paper which came today: https://www.itute.com/wp-content/uploads/2022-NSW-ESA-Mathematics-Standard-1-Solutions.pdf

and so now all the 5 papers have solutions. The others you may find in the relevant threads on this forum.
