Ah. Could be from an old MIS paper. They used to distinguish between "dividend" and "yield". Dividend was related to face value and Yield was related to market value. In the General course now, we just need to know "dividend yield".

There are a couple of terms here to remember. The face value of a share is the nominal amount that is literally written on the share. In this case the face value of the share is 50 cents. The market value of a share is the price which someone might be willing to pay for that share. In this...

It's all cyclical. Every club have their ups and downs. Look at Manly! Or the Roosters - this time last year they were last! So at the moment, Canterbury are on the way down. Tough it out mate.

Don't forget the usefulness of the Probability of Complementary Events. You've already worked out P(rain on 3 days) = 1/64 Now, P(rain on 2 days) = 3 x (3/4 x 1/4 x 1/4) = 9/64 So, P(rain on at most 1 day) = 1 – P(rest) = 1 – P(rain on 2 or 3 days) = 1 – (1/64 + 9/64) = 27/32

You could of course use a tree diagram to do the question. You'll find two branches where I and J take up the positions out of the 20 branches, which gives the answer of 2/20 or 1/10. But there comes a point where making a tree diagram becomes impractical. This is where you'd opt for the...

As someone once said to me, 100 always scales to 100. So if you do well in the exams, you'll always get a good UAI. Bottom line is ... do the very best you can do. Everything else is outside your control, so there's not much point stressing about it.

PERFECT working would be something like: (a) Number of ways = 5! x 4! = 2880 (b) Number of ways = 4! x 3! x 3! = 864 In other words, make sure your answers are labelled clearly using the nomenclature of the question (i.e. (i), (ii), (a), (b), etc). State clearly and briefly what you're trying...

Try integrating with respect to t. We know that a = –10 Since initial velocity is 12 m/s, we have v = –10t + 12, or v = 12 – 10t. Since the particle starts at the origin, we have x = –5t2 + 12t. Don't forget the simple stuff!

Clearly you lot need to get out more. It does say "of all time". 1. Pac Man 2. Tetris 3. Super Mario Bros 4. Galaga 5. Lode Runner

The original name was actually Puckman!

Loans are ALWAYS present value questions. The amount borrowed is the present value, and you always use the big formula. Some questions will say something like "what lump sum invested now". They're present value questions. The formula you use will depend on the information given in the question.

Yes, provided that theta is in degrees.

EXERCISE 8H 7 (a) (a - b)2 = a2 - 2ab + b2 = a2 + 2ab + b2 - 4ab = (a + b)2 - 4ab 7 (b) (i) a + b = 3 ab = 1 (a - b)2 = 32 - 4.1 = 5 (ii) a + b = -5 ab = -7 (a - b)2 = (-5)2 - 4.-7 = 53 (iii) a + b = 7/3 ab = 2/3 (a - b)2 = (7/3)2 - 4(2/3) = 25/9 7 (c) (i) √5 (ii) √53 (iii) 5/3 13 (a) a + b...

EXERCISE 8F 12 (a) y = 2x2 - 7x + 4 dy/dx = 4x - 7 We need the slope of the tangent to be 1 .: 4x - 7 = 1 4x = 8 x= 2 When x = 2, y = -2 At (2,-2), b = -4 12 (b) y = 2x2 + 3x + 1 dy/dx = 4x + 3 Gradient of tangent = -a/b = -2/1 = -2 .: 4x + 3 = -2 x = -5/4 When x = -5/4, y = 3/8 At (-5/4,3/8)...

This stuff is really strange at first but it's quite simple. Four steps. 1. Write down the MEASUREMENT. 2. Write down the PRECISION ... how accurate is the measuring device? How many decimal places? To nearest whole number? To nearest 10? Stuff like that. 3. Write down the ABSOLUTE ERROR ...

Another way ... The total amount is $123.75. This includes the cost of the meal as well as the 10% GST charge. The cost is 100% of the cost. The GST is 10% of the cost. So the total amount is 100 + 10 = 110% of the cost. Now 110% of cost = $123.75 So 1% of cost = 123.75 ÷ 110 = 1.125 Therefore...

Isn't this just a normal present value question? N = M[ (1+r)n–1 / r(1+r)n ] = 700[ (1+0.0075)36–1 / 0.0075(1+0.0075)36 ] = 700 x 31.44680525 = $22 012.76

(i) S = Vo – Dn Vo – Dn = S Vo = S + Dn (ii) S = Vo – Dn S + Dn = Vo Dn = Vo – S D = [Vo – S]/n (iii) Just in case you need the other possibility ... S = Vo – Dn S + Dn = Vo Dn = Vo – S n = [Vo – S]/D Hope this helps. :/

1/a + 1/b = 1/8 b/ab + a/ab = 1/8 (a + b)/ab = 1/8 Now cross multiply: 8(a + b) = ab 8a + 8b = ab 8a = ab – 8b 8a = b(a – 8) .: b = 8a/(a – 8) So there's an equation for b in terms of a. You can substitute any value in for a and get a value for b. If a = 1, b = 8(1)/(1 – 8) = 8/-7 = -8/7 If a...
