VCE Further Maths Exam 1 Discussion and Solutions

How was question 16 (Core) A, doesn't make sense. I chose D btw

this involves correcting for seasonality:
1/1.6=0.625
so the actual sales should be reduced by 37.5%

Shouldn't question 8 be D? (Core)

No because if you look at the scale of the graph, the y-intercept wouldnt be 17.4

[znjar]

shouldnt 13 CORE be D?

Why is the answer question 23 D?

Assuming the interest rate increases 0.51 each time - this means that #20 interest rate = 28.93...
Then, 7500 - 7233.83 = 266.17 (the total amount paid) minus the #20 interest rate of 28.93 (266.17 - 28.93) = 237.24
Hope it makes sense, someone else might be able to explain it better....

How come question 13 doesn't have seasonality? I chose my answer as C, because seasonality can be weekly, and there is a decrease at around day 2-3 in each week. I'm guessing this is because this is only a small part and overall you can't see any obvious trends but if someone could further explain why I would really appreciate it

Well according to the suggested solutions I've lost 3 marks in total. Is a 45+ SS still possible if I do well in exam 2?

Why would question 12 in the core not be D? And question 13 clearly has to B, there is no overall trend or seasonal pattern.

[dec.hargreaves]

my answers are all the same except for networks Q8 which i got C for. anyone else??

[ella.bazza]

Just a few questions concerning the solutions here-

Why is Core question 2 B, I thought the whole point of upper and lower fencing was to modify the boxplot and the 5-point summary, so why wouldn't the answer be C?

Also, why is Core question 6 E?

And for networks for question 7, how is C a correct statement? Like why is the answer D?
