3 was definitely C. There were 6 people. e.g ABCDEF 2 must be pickedits not 15, its 30. Its unordered, there is no need to divide it.
The initial $119.40 + $402.70 is what she would get if she didnt earn more than $236/fortnight. However, because she earns $300, the total she gets from the gov, is $119.40 + $402.70 - ($64x0.5$) which equals D
I got C for that using the cosine rule to find that angle ABC = 19 degrees, then 180 - 19 = 161 degrees. It's not possible for it to be D because you start from north.9 is d because interest rate has to be divided by 4 and period multiplied by 4
20 is d because its the bearing OF c FROM b. if anything, its between b and c
20 is not D its C. you must have done town b from town c whereas the question is town c from town b.I think this is 100% correct. Feel free to make changes.
Yea, it was a typo. Sorry for the confusion.20 is not D its C. you must have done town b from town c whereas the question is town c from town b.
Everything else is what i got so im pretty sure you got 24/25
100% AGREE. Put d for both instead of cBoth 9 and 20 are C. Otherwise the list that study-guy posted is correct.
For 9, D is incorrect because you have to change the interest rate to fit the compounding period (quarters), so it would be 1% for 8 periods which is 1.083
For 20, you use the cosine formula to find cos-B and then subsequently find angle B. angle B is 19, and you subtract that from 180 to give you the bearing, which gives you 161. D is definitely incorrect, as a bearing of 341 would be in the top left quadrant.
