Where do I find a copy of the Further Exam 1 2021? Does Atar Notes publish it anywhere on their site?

If \(C, D\) are independent events then by definition \(P(C \cap D) = P(C)P(D)\).

This means that \(\frac{P(C \cap D)}{P(D)} = \frac{P(C)P(D)}{P(D)} = P(C)\). Note that what you've written there 0.42 x 0.17/0.17 is the same as the answer they've given.

Hi,

First of all hope you exams goes well.

Now about your question. You need to be able to pass unit 1 and 2 for all your year 11 subject. It does not matte by how much but it is essential for you to pass unit 1 and 2.

Hope it helps. And again best of luck for your exam

Hello,

I am looking for confirmation of my working or correction of errors.

For A, I got 0.75%

For B, I got t(0) = 55000, t(n+1) = 1.0075 x t(n)

For C, I got t(n) = ((1.0075)^n) x 55000

For D, the one I am stuck on, I got $86,112.46. I understand the question as that the rule in part C is for n months, not n years, so t(60) would give the value after 5 years.

Thanks

Hi,

Just looked over all your answer I think they all are correct. The only think I would say would be for C. My teacher had told me that rule should always be written as Vn = V0*R. Though this is just a small part you should just confim with your teacher.

Also for last you would multiply 5 by 12 to get how many months it would be for 5 years.

Hope this s somewhat helpful

What is the difference, if any, between a question asking for "the first five recursions" and "the first five terms"?

I’m not sure if this is correct, so someone might want to confirm.

I would assume ‘the first 5 recursions’ means to apply the recursion rule 5 times (e.g. given V0, find V1, V2, V3, V4 and V5), while ‘the first 5 terms’ means the first 5 values in the sequence (e.g. V0, V1, V2, V3 and V4).

I would start by converting the ratio to fractions, to work out what fraction of the cost each person contributed. You can add up each number in the ratio to get the denominator of the fractions, then use each number in the ratio as the numerators.

Spoiler
The sum of the numbers in the ratio is 10, so Mark contributed 3/10, Henry 1/10, Dale 4/10 (2/5) and Ben 2/10 (1/5).

Then multiply each fraction by the total cost to work out how much each person paid.

G'day,

I am a tutor in Further Mathematics, but have a question for fellow experts and students.

The picture attached is of a question my student attempted. The content is on chapter 3 of cambridge, so is on least squares regression. A few issues:

- The original data has a massive outlier, so shouldn't even be subject to least squares regression per the assumptions

- The picture is of the residual plot, which to me has no real observable pattern given the outlier, however perhaps the definition of "pattern" is not so clear cut? I imagine the pattern being non-linear or curved or some such, so how do we distinguish between pattern and non pattern?

Thanks for the help. Hopefully someone more zen than I can help me understand why we'd approach this question despite the outlier being present!

Cheers
