Solution above, MPC = ΔC/ΔY and MPS = ΔS/ΔY

k = 1/1-MPC or 1/MPS So going back that 2011 HSC Question, MPC = ΔC/ΔY = 90/150 =0.6 k = 1/1-MPC = 1/1-0.6 = 2.5 Therefore, New equilibrium income = Previous equilibrium income + k x ΔI = 300 + 2.5 x 40 = 400

You use the multiplier and/or MPC rather than Y = C + I I believe, not entirely sure.

Tim Riley has a 10/10 explanation on this, but I dont think it will be tested due to the amended syllabus change in 2010. Chuck the 0.8y over to the left hand side. 1y - 0.8y = 0.2y (m8 math).

y = c + i y = 100 + 0.8y + 40 0.2y = 140 y = 140/0.2 = 700

7 (a) Simply equate the coefficients of x^r for both sides. 8 (a) If you inspect the expansion of (1+x)^n you realise the expansion is actually that sigma form when you let x=1 9 (a) Simply equate the coefficients of x^(n+r) for both sides.

Agreed, look at Joffrey Baratheon nuf said.

Pb2+ + 2Cl- ⟶ PbCl2(s) n(PbCl2) = m/M = 0.595/278.1 = 0.00214 mol n(Pb2+) = 0.00214 mol m(Pb2+) = 0.00214 x 207.2 = 0.4434 g c(Pb2+) = 0.4434/0.0500 = 8.87 g/L

Yes

Become rank 1 and you can achieve any atar you want.

Not really, those who worked hard in school assessments deserve to be more awarded than those who slacked off. This is why you need to push everyone to destroy the external exams.

http://www.boardofstudies.nsw.edu.au/hsc-results/understanding.html The school mark will be moderated based on your cohort's performance. Let's say you are the middle of a cohort of 3 students, and you all respectively earned school internal marks of 70, 63, 60. However in the external exam...

Internal mark and final report mark you mean what your school gives you?

If you're first then yes. However, your external performance will not affect your moderated assessment mark much (most likely still dragged down) if you in the middle of your cohort.

Good luck finding that student, although maybe Jonah Soewandito might accept since he'll have plenty of time since he'll finish HSC at 12 years of age.

Time yourself.

2014 worse aligning srsly.
