i don't understand how you guys got 9 haha please explain
because there are 30 scores right, and the 15th and 16th numbers form the median, so the median is 11, which leaves 14 on each side, and then the 7th and 8th numbers from the median make Q1 and Q3 which are (7 and 8) and (18 and 18) so yeahhh, im just confused!

The question asked only for the female scores.
So there's 14 scores total.

yes yesss i now sadly realise :'(

This is definitely right. I knew it as soon as i left the exam room. Did it on maths online and all. I think you would still get one mark though, if u didnt do this, right?

Oh well i don't know my final answer was 10165 km (nearest km)

I put the 1/2^10 because it was the probability of getting a tail on the 10th toss aka 1/10x1/10x1/10x1/10x1/10x1/10x1/10x1/10x1/10x1/10... i hope im right ahah

Answers ranged from 159-162, depends on if you used the rounded figure from the previous question Or used the un rounded answer, either way the answer should be right

How did you get your answer?
I added 180+31
=211degrees
:s

6 is d
if you let a = 1
and x = 0
you get a y intercept of 1, works for every other value greater than 1
so its D

was it possible to make that shape out of 543 sticks (at the start). I got no?

 

[lukasheights]

Was there any need to draw a tree diagram today or convert currency?

I can't remember but they seemed non-existent in this test, as well as having to differentiate from population standard deviation and sample standard deviation.

i got no too

 

[StewMcGlinchey]

You had to use alternate angles to find the 55 degree angle, and the Sine Rule to Find ACB then add the ACD, 55 and 180...I got 261

 

[Chrissiee]

omg arent you guys freaking out.. why are you going over it? It's done! forever! stop thinking about it already!

I also said no so let's hope that was right!
That was the Q23biii on whether you could create a figure with 543 sticks

 

[jononie]

I got 9
Median = 17 (so then there's 7 scores on either side)
Lower quartile = 11 (Middle of lower than median scores is 11 with 3 scores on either side)
Upper quartile = 20 (Middle of upper scores from median is 20 with 3 scores on either side)

+1, this is correct

What was Question 6 again?

 

[StewMcGlinchey]

pretty sure it's just 9..The Q3 was 20 and Q1 was 11...the median was 17

 

[2011_]

fair enough, what was cut off last year? do you know? cheers

No, sorry, I don't. Would love to know

 

[jakeantoun]

I also said no so let's hope that was right!
That was the Q23biii on whether you could create a figure with 543 sticks

nah you couldnt, i made that mistake and said you could make a figure of 181. this is wrong, you cant make a figure with 543 sticks joe

 

[jessxxxr]

What was Question 6 again?

6 was which of the following graphs best represents the equation y=a^x, where a is a number greater than 1
