The "charged monthly" is the rate at which interest in being charged. So since the rate is 15% p.a. 15% is the yearly rate. You need to divide by 12 to get the monthly rate you are being charged. Annual meaning yearly. Note p.a is per annum meaning per a year. Installment is referring to the...

So long you know the definitions you understand question you should be able to do it. q a) look like a parabola c) something like (x+3)x(x-3) but with turning point at x=+/-1

What is MDP? Thank you Never seen engineering report like this before. The graphics were really good.

@ specificagent it look like Jimmy has answered Just couple points - Make sure to remember the definition of conditional probability - What is the relationship between logic and set theory operators - When do you use bayes theorem over the definition of conditional probability

What I like to do in these scenarios is use wavy equal signs. This way it is understood rounding is occuring. General I think the standard is round to two decimal points or 2 significant figures but there are no hard rules to my knowledge. So in 21 a) you could have written T = <some math...

1. Both degrees will be awarded 2. No set rules

Is this for uni? You may find some uni books have yr 12 content. So that might be worth looking into. Somes courses may require specific content from textbooks so you may not need all the content from 3 unit. So you may not need understand mathematical induction though you may come across it.

I think Ken Webb as mention by ahri is good

Yes thank you. I think might be missing the one from two families

c) The mean number of children per family = Total_num_children / Total_num_families = (0*k + 1*2 + 2*9 + 3*6 + 4*7) / (k+1+2+6+7) =2 # Note we just need to make k the subject => (2+18+18+28) = (k+1+2+9+6+7)*2 => k = (2+18+18+28)/2 -1 -2 - 9 - 6 -7 => k = 8 Edit forget subtract 9

MODE The 0-8 is correct however remember k is positive so it would be 1-8 MEDIAN We need to find the middle value. The middle value is given by (k + 2 + 9 + 6 + 7)/2 Let just be creative for bit. If k = 1 Then middle_value = 12.5 meaning the median is 2.5 if k = 2 => middle_value = 13...

So do you know how the mean, median and mode are calculated? Just give it a ago see what equations you get.

Real maths and competition maths are different.

You just need to take look at the graph. If you know what f'(x) (i.e. f prime of x ) it should make sense. We can see clearly at [4, 6], f'(x) = -3.

The m = -3 comes from graph the being f'(x). The working weirdly set out. Not sure why they just didn't integrate from 0-6. And then equate f(6).

I am not sure if the excel textbooks are suitable for history due to large variety of topics content is not cover indepth but I have done history from quite a while back so I may be mistaken. Have you consider any other resources.

I won't give the full answer. But 6.75% per annum / 12 = 0.5625% = 0.005625 So A1 = 159000*(1+ 0.005625) - 1415 For d) make the loan payment amount the subject. So replace 1415 with loan_payment_amount in d)

Mainly in Machine learning engineer, data scientist or data analyst

That is UNSW, UTS has more flexibility
