Do you include lump sum payments in total interest paid during lets say, a reducing balance loan?

Are you talking about the lump sum of like an initial deposit that is payed, then reducing balance for the remaining value?

I would not think so as we don't pay interest on lump sums.

Yep. I now realise you wouldn't include interest on it, but would u include it in total amount paid for lets say a car.

Yeah you would, it's still a payment.

Do you mind telling me which trial you did this question on? We had a simillar question on my SAC, butI haven't come across any yet in trials, I just wanna make sure I haven't forgotten how to do it haha

Hi! Could someone please explain why 30% is the answer?
I don't the question or how to work it out at all... and it's the only one in the practice exam I couldn't get..

I'm not sure if this is the right way of doing the question but you could say there are 120 rooms (as winter has 100% occupancy) and in Summer only 85 rooms are used. To have 100% occupancy in summer, you would need to close 35 of the 120 rooms which is equivalent to 29.2%.

Hey can someone help me with the 2017 NHT exam 1 question 7 from core? (Am I allowed to copy and paste the question on here?)

[Lear]

Yep you are!

[userrrname]

Alright, so why is the option C?? Thanks in advance!

Question 7
A least squares line fitted to a scatterplot will always
A. maximise the number of data points lying on the line.
B. equalise the number of data points on either side of the line.
C. minimise the sum of the squares of the vertical distance from each data point to the line.
D. minimise the sum of the squares of the shortest distance from each data point to the line.
E. minimise the sum of the squares of the horizontal distance from each data point to the line.

Ah yup, that really just comes down to knowing the definition of what that line is. It’s not really something you can ‘work out’ during the exam. It’s just a fact you are supposed to know.


Questions like these scare me the most as I don’t plan to take my textbook in and this sort of random things I dismissed when making my personal bound reference. Plz don’t do this VCAA

Are you serious... it’s like they make us focus on application questions so much that we ignore the “content” and then surprise us with a... definition??? This shit better not pop up on Friday

Its not really about definition, its about understanding. We should all know by now that adding all residual equals to 0 and that residual is vertical distance between the line and the actual dot, so by using the previous example. Its pretty obvious...

hey everyone, sorry if this question has already been answered but just in regards to time series plots, are irregular fluctuatiosn ALWAYS a feature? according to question 11 on the NH 2018 exam 1 examiner's report, they are but im not quite sure if this is right. thanks!!
