Has anyone done them?

I'm helping out a friend. I'd just like to compare my working before I teach the wrong stuff

The paper i'm referring to is located on this site:

(sorry, don't want to be deep-linking)

Just answers will do.
And if you'd like I'll put my worked out answers up later.

I did the Mathematics School Certificate Test in 2004. I practically know the answers to all the questions. I'm very proud of my performance in that test since I got 98 for it, but at the same time I was a little frustrated since I discovered that the two marks that I lost WERE MULTIPLE CHOICE QUESTIONS!!!!
Ask me, if you want to know any answers.

What's a 'Stem and Leaf' plot?

 

[velox]

like this

5 I 1 2 3 4 5
6 I 4 5 6 7

so basically the numbers i have in there are 51,51,53,54,54,64,65,66,67. I think u get the point.

MISTAKE:

Section 1
Q13
You calculated the AREA of the trapezium. The question asked for the PERIMETER of the trapezium.
Solution:

The unknown side was found by Pythagoras' theorem: 3² + 4² = 5²
Perimeter: 4 + 10 + 13 + 5 = 32cm


Also, when doing stem and leaf plots, I don't think you are meant to put commas between numbers since you know that they are the last digit of the score. There should be a line between your stem and leaf so you won't get your numbers mixed up. However, you shouldn't lose any marks for not doing that. Just being a little bit technical and precise.

Otherwise, the rest should be correct.
24/25

lol, i should read the Q eh?
Thanks for that.

yeah, i still don't know stem and leaf. I don't think I ever learnt that...

Now to do the other parts with explanations...

and btw, it wasn't 24/25
I did miss out some Q's cos too lazy to draw, and that last Q. Putting a ruler to the computer screen isn't that smart.
