yeah might be cooked on that one

them giving it does not mean we have to use it. Because is it even an annuity if its a lump sum? just compound interest no?

what answer did you get?

 

[katiekms]

does anyone remember the answer for mcq 15? i said D because it had a different 5 number summary than the others, and other people agree, but some people are also saying C. does anyone know?

I did C, only cuz histogram is meant to be joined and there were 2 seperate ones but i might be wrong

1. i worked out the total amounts that were taken out over the 15 and 10 years
2. added both together, then used that (i think it was 360,000) as the FV in 360,000=PV(1+0.02) power of 300 or whatever the periods were
3. then just algebred shit up and found the minimum PV to have at least the sum of everything taken out, (in the high 200,000s)

yeah im pretty sure i did that

Honestly I forgot the paper I don't wanna think over math I either did good or bad lets leave it at that

i copied the method from the 2020 last question which was the exact same different numbers. i did the thing for 10 years (A), then i did it for 25 years with the different amount (B) then for 15 years with that amount (C). then you do A+B-C which was some number i think in the 300,000s. this is how they did it for the 2020 question

 

[mysterymarkmachine]

yea i just had a look at the 2020. think i missed it

same

wait you know the bearings question for the BC one where you had to find the bearing of C from O. Did you guys get 220T?

bruh i got 220 but i didnt write "220T" i just did 220 degrees so would i still get the marks?

 

[utopianimal]

since

i can’t fully explain without the question, but since you were given some of the bearings, you were able to figure out the angles for some parts of the circle. then i did something else i forget. and then, because it’s a straight line, the bearings on either side would be symmetrical so you can reflect the angles you found onto the bottom part of the straight line, and then it’s the angle + 180. i can’t remember fully but i think it was 220° or something like that?

yeah i got 220 too

bruh i got 220 but i didnt write "220T" i just did 220 degrees so would i still get the marks?

pretty sure they would be lenient

yes, in all of the hsc paper solutions i’ve seen they NEVER include the T for some reason, so they would surely give you full marks. plus, on the diagrams they don’t include the T either. i think it’s optional.

Yea you don't need it, pretty sure its cuz there's one textbook which says you have to do it while the others say the opposite

 

[ihatehsc24]

what do you guys think a raw 75 will align to?

 

[Demons]

what do you guys think a raw 75 will align to?

probably mid or high band 5

come on bro I think you did better than that at least raw 80.

 

[utopianimal]

bruh when i left the exam i was so confident for 90+ but now looking at the solutions im looking at 80-85, does anyone know whether the moderation would make this higher and by how much roughly??
