I am not 100% as to whether they will be correct but I am very certain that they are right.

1 A finding the right expression question, my answer is 3k^2
2 C surface area question, my answer is 52
3 A stem-and-leaf plat question, my answer is 24 which means it is 4.
4 D choosing the right diagram question, my answer is D - exponential graph
5 B finding the smallest angle question, my answer is 47 degrees
6 B tax question, my answer is 10824.40
7 D Luke's double time question, my answer is 9
8 C finding the median question, my answer is 14.
9 A finding the value of SQRT ((x+2y)/8y) my answer is 0.69
10 D Science & Maths test question, my answer is interquartile range.
11 B area of the shower question, my answer is 9921
12 A scatterplot Q, my answer is 'positive"
13 C height of each student question, my anwers are 149 and 171
14 B kite Q, my answer is 66
15 B Speedboat question, my answer is 5600
16 D Marble Q, my answer is 6 Blue, 5 Red, 5 Green
17 A bearing question my answer is 060T
18 A car registration plates question, my answer is 26^3 x 10^2
19 B height of a mould question my answer is 78
20 D finding the distance from the top of the tower to the P, my answer is 14.42
21 B comparing volume question, my answer is 3:1
22 C dice question, my answer is that the number of 6 is three times likely.

I may be incorrect due to my lack of some important terminology related to statistics that I haven't learn since I am not doing General Mathematics.

So be wary that my answers for Q10 and Q12 may be incorrect.

I will post up the writing questions once I get to come back to them around this afternoon.

you got question 3 wrong.... the answer was 4 not 24, because it was asking for the specific digit of "n" not the range

and i think my question 1 was different from yours.... wasn't sure about that one though

#### lyounamu

Ok, sorry.

first one is definitely 3k^2

I think you guys are getting 18 wrong.

I got C - 26^4 x 10^2

26x26x10x10x26x26 = 45, 697, 600

Correct me if im wrong. #### taker0

Correct me if im wrong. it said that M was already at the begining. so i think that takes off a power.

Ahhh i didnt read that bit. Stupid question =\

I keep thinking 18 might be C?

26 x 26 x 10 x 10 x 26 x 26= 45697600

26 to the power of 4 x 10 to the power of 2 equals this

meh, better get studying to smash legal tommorrow... is anyone else thinking all the exams so far have been pretty much worse than trials? (with the exception of english

^ Yep, I thought it was that too until I luckily re-read the question and saw that it said the first letter was M

So what are we saying the answer to 3 is?

what are the options?

#### Kiim2507

3 is A

What is the value of N when the highest score is 67 and the range is 43?
67 - 43 = 24
But since it's a stem and leaf, the 20 is already there so N is 4 (A)

ive seen another question like that were is said that answer as the represented number because is asked for the value and the value of N was 24 all though the actuall number there would have been for but the value of it is 24

#### Kiim2507

##### Member
I'm 99.9% sure it's 4 because N was in the spot where the 4 would go

If the question hadn't given us the stem and leaf plot then yest it would be 24 but because 20 is already represented by the two N = 4

for MC 18 i think the answer is D cause the question says letters and numbers may be 'Repeated'
