VCE General & Further Maths Question Thread!

Can someone please help with this question from the 2017 Insight paper: (geometry and measurement)
A teacher, located at Torquay (38 S, 144E) releases the results of her exam to all students at the same time.
What time will student Georgia who is in Terang (38 S, 142 E) receive her results if the teacher releases them at 9:30 a.m in Torquay?
a). 9.22 am
b). 9.30 am
c) 9:38 am
d) 10.00 am
e) 10:38 am

To me the answer should be A as Torquay is further east than Terang and would therefore be ahead in time, but the answer is C?
Am i reading this wrong?

Thankyou!

I forgot they updated the Geometry and Measurement module. This is one of the newer things. I think you might be right though. -2 degrees in longitude should yield 8 minutes earlier. I may be wrong though because, like I said, this isn’t something I have done.

So....where they both ordinal? Someone please say yes. You can order them by sweetness from lowest sweetness to most sweet (light->scented->sugar).. i changed my answer from ordinal&nominal to ordinal&ordinal in literally the last 7 seconds before handing in the paper. I decided to bite the bullet just incase VCAA decide to be annoying with this question.

Pretty sure it was ordinal & nominal!

But you can order them and isn't that the same justification that vcaa had for last year with under and over 50?

Last years is very very clearly ordinal. But this years....not as sure

It’s nominal most likely (in my opinion) as saying that light, scented and sugar is ordered is almost the same as saying red, orange and yellow are ordered.

There is no interval between the values: ‘light, scented and sugar’ like all ordinal data do (e.g. level of satisfaction, shoe size) to confirm this. I think if instead the level of sweetness was worded differently e.g. high sweetness, medium sweetness etc. it would have been more clear as ordinal.

But....red orange and yellow can be ordered by wavelength

If that’s the case then types of animals can be ordered by evolution/genetics😄(I don’t do bio so don’t mind my wording😂)

I found question 8 of geometry tricky. Did anyone understand it

[elle6299]

Hey, I was just wondering if when working out bearings, is it always in a clockwise direction and never anticlockwise?
Thanks in advance!

I found question 8 of geometry tricky. Did anyone understand it

Using the copy of the exam, I can tell you that Geometry Question 8 can be calculated by forming an equilateral triangle using the radii of the three circles and subtracting out the area of the three sectors you've formed inside the triangle. If that doesn't make sense, PM me and I'll draw it out for you after I've completed my own uni exams (I have one left).

To all Further Class of 2017 students,

Please do not be bogged down by Exam 1 any more. There's no use crying over spilt milk.
Learn from your mistakes, keep going and don't give up! These ~48 hrs can be used productively to revise for Exam 2, if you so choose.
There is currently a list of Exam 2 potential questions for viewing.
Keep your heads up, think forward and do your best. Don't look back.
You guys can do it! Good luck.

Hey guys,
For Exam Two, it say that for financial math all answers should be rounded to the nearest cent unless otherwise instructed.
Does that mean for a value of say $1865.292, do i round to $1865.29 or $1865.30?

Thanks and good luck to all on Monday

For the Median smoothing questions where they usually ask "Complete the three-median smoothing by marking each remaining smoothed point with a
cross (×) on the time series plot below." -- Do you have to join the line at the end between the crosses after they have been plotted or not? I've been seeing some inconsistencies.. so I'm unsure.. Cheers

In that scenario you'd round to $1865.29, however if it was $1865.295, then you'd round to $1865.30.

I've never done this module so I could be completely wrong. But if the teacher releases them at 9:30, then there is no way that someone could get the answers earlier than that
