BEST THEOREM EVER
davidogrady — 13/06/16
lol ya was certain it was pythagoras before it all
sorecauvanesa — 13/06/16
I only learned theorems 19 and 14 so I didn't know how to structure it
Elisha447 — 13/06/16
It wasn't too bad. What graph did you draw to show 2015 and 2005? I did 2 histograms but I think it's wrong :(
jackkfleming — 13/06/16
I did a bar chart and put each similar bars beside each other like they do in some questions from the paperes
Ooooooooo — 13/06/16
Would a line and plot graph be ok?
jackkfleming — 13/06/16
ya
Elisha447 — 13/06/16
Does anyone know if a histogram was okay??
davidogrady — 13/06/16
i did a histogram aswell ,twill be grand
Elisha447 — 13/06/16
Ok Thanks :)
davidogrady — 13/06/16
was that a simultaneous equation towards the end or not ?
Ooooooooo — 13/06/16
Yeah it was a simultaneous equation
davidogrady — 13/06/16
oh god
Liam_4376 — 13/06/16
how did you do the area of a circle touching the triangle points?
davidogrady — 13/06/16
what did ye get as an answer
Ooooooooo — 13/06/16
X=3 and y=-1
davidogrady — 13/06/16
oh okay
mathswhiz101 — 13/06/16
the hypothenuse of the triangle was the diameter of the circle
mathswhiz101 — 13/06/16
Ye should all be studying for CSPE .....
davidogrady — 13/06/16
yes exactly
Whitestar — 13/06/16
fcuk the paper
Emma_5811 — 13/06/16
Terrible didnt have a clue
xroisinx — 13/06/16
was a stem and leaf graph okay for showing the 2015 and 2005 information?
SryanBruen — 13/06/16
Yes it was a lovely paper. It was very easy and I'm glad it didn't turn out like I thought it would.
cmck134 — 13/06/16
What was the area of the circle, anyone get 61 over 4 pi cm2
annie1996 — 13/06/16
It was horrible ! Like how can you find the surface area is there are no numbers?!? I'd be lucky enough to get a C
Dok101 — 13/06/16
@cmck134 Yeah Im pretty sure I got that
ug_roland2504 — 13/06/16
the bigger box sides were 2 units the smaller box sides were 1unit it was in the question
SryanBruen — 13/06/16
Yeah those were in the question Annie? ^. Though they were strange to be honest, like it said find the AREA, so my unit of measurement was units squared? (I never saw that before....)
ug_roland2504 — 13/06/16
i got 28 units squared for that question
darraghob — 13/06/16
are 2 pie charts ok for the graph question?
mazink0204 — 13/06/16
Steam bruen calls it easy, then gets a c
SryanBruen — 13/06/16
I will not get a C ya weirdo.
annie1996 — 13/06/16
Or the question on coordinate geometry where they asked about the circle ? Like what was that ? 😂
Gift_3466 — 13/06/16
Did anyone at all know how to do the last part of the last question. q 12, like I only got A but how were you supposed to find B and C???
Theresa_3825 — 13/06/16
For C, you use 1\2 x a x h. I used Pythagoras to find h (height). For B, you multiply 12 by x. You got x in part (i) of question 12.
Elisha447 — 13/06/16
For b wasn't it 12 x 7?? Because it was the same as a ? Maybe not 😂
Theresa_3825 — 13/06/16
I got 12 x 7 for one of them. I can't remember which side was what letter 😃
Gift_3466 — 13/06/16
Ohh, I thought the two were separate shapes all together. Well thanks for the explanation
Theresa_3825 — 13/06/16
So did I. I only realised 10 minutes before the exam was over 😂
Gift_3466 — 13/06/16
Did you ever get an answer for the cubes and right angle triangle question??
Theresa_3825 — 13/06/16
Yes. I'm not sure if I got them right but for (i) I got 30 units^2. For (ii) I got root 8 or 2 by root 2. For (iii) I got root 17. For (iv) I got 2 by root 17 over 3. I forgot what it was in decimal form. It's over and done with now so don't stress out 😊
Gift_3466 — 13/06/16
Okay I won't, I just hope I did well enough anyway
Aimeedonaghey01 — 13/06/16
Was a stem and leaf diagram okay?
SryanBruen — 13/06/16
Am I the only one here who did a Trend / Line graph for that question?
Aimeedonaghey01 — 13/06/16
I know a couple who did it so I say you're fine
Aimeedonaghey01 — 13/06/16
People*
needhelp101 — 13/06/16
WENT ABSOLUTELY HORRIFIC. theorem 19 and 14 both didnt come up at all. Failed it.
EH458 — 13/06/16
Did anyone else do a two way stem and leaf diagram for the question with the % of female parliament members? That was one of the only ways I could think of doing it
EH458 — 13/06/16
I think I did perfectly fine in paper 2, went smoothly enough I think 💁🏼
Suitcasey114 — 13/06/16
Did anyone else do a bar chart,for the female members of parliament?
Andrew_7539 — 13/06/16
Did anyone do a stem and Leaf diagram
SryanBruen — 13/06/16
Suitcasey114 I was going to do a bar chart but then I thought that it would look messy. I thought that a line graph was the clearest and least messy graph I could do.
Suitcasey114 — 13/06/16
I don't see how the line graph would work,though.I'm not being rude,I just can't see it.Looking back,stem and leaf would have been the best,but I didn't think of that.Only thing is,because a bar chart is so clear (to me,at least) I didn't do workings,and just drew and labelled the bar chart.If it's wrong,I'm screwed
SryanBruen — 13/06/16
It would work 100%? You have two lines and you plot the points on the figures of the graph. Then connect the dots and make a line.
SryanBruen — 13/06/16
I also use two different colours for lines and make a key to tell which is 2005 and 2015. I used the boxes for 1 country per box and there was 28 countries. If I did a bar chart, it would look real messy and confusing - I would have to make every bar small and tiny to fit in with the small boxes. It is for this reason why I didn't do one of them and did a line graph instead.
Suitcasey114 — 13/06/16
I'm starting to see it now,but I still think stem and leaf would have been best
SryanBruen — 13/06/16
Yeah I'm not looking for an A bro haha. I'm looking for a B.
SryanBruen — 13/06/16
But yeah to answer people's questions about the stem and leaf, they are perfectly acceptable because the question says: Display the data GRAPHICALLY in a way that allows you to compare the data for the two years. Label your graph(s) clearly. Show any calculations that you make. And it says on the internet: "A stem-and-leaf display is a device for presenting quantitative data in a GRAPHICAL format". I hope this answer your question
Theresa_3825 — 13/06/16
Would 2 separate histograms be okay? I used the frequency table.
SryanBruen — 13/06/16
Yes it would be acceptable
needhelp101 — 13/06/16
What if you used one histograms but put them both on it ?
ug_roland2504 — 13/06/16
if you do 2 histograms you are not really comparing them. You are just showing each graphically as individuals not in a comparison.
Blathnaiddoolan — 13/06/16
What did you get for question 12 (b) (i)???
SryanBruen — 13/06/16
My workings out of that Blathnaiddoolan Soh, Cah, Toa? I just used Tan (though it's not a right-angled triangle....) Tan 70 degrees = x/7 7 Tan 70 degrees = x 19.23cm = x I probably did it wrong LOL
ug_roland2504 — 13/06/16
it was something like 10.23
SryanBruen — 13/06/16
Can u show me how u got that? ^ Like see how I got mine
sethreed — 13/06/16
you had to spilt the isosceles triangle into two to get two right angled triangles
Fiddlestix — 13/06/16
Guys anyone do pie chart ?? So worried!
Blathnaiddoolan — 13/06/16
Thank you what about 7(b) 8(c) and 5(a) ???
Theresa_3825 — 13/06/16
For 5a I said no because you end up with 6 which I not equal to 0. For 7b, I got 90 degrees. I used SSS to prove congruency. For 8a, I think I got 16 degrees or something. This is the smaller angle because the other angle was 74 degrees roughly.
SryanBruen — 13/06/16
Yeah I got that for 5a.
Blathnaiddoolan — 13/06/16
Yeah I got all of that aswell
Kagalwala — 13/06/16
For 7(b) I said the angle in a semi circle is 90 degrees which is why y is 90.
darraghob — 13/06/16
Yah fiddlestix I did two pie charts for the graph question
Theresa_3825 — 13/06/16
Kagalwala, I think that might be okay too. I mentioned that |AC| was the diameter too because why not 😂
sophie544 — 13/06/16
The answer for that question was 80 degrees as it was a cyclic quadrilateral and opposite angles sum up to 180 degress
Fiddlestix — 13/06/16
Thank you so much for letting me know! Relieved daraghob!
Fiddlestix — 13/06/16
Thank you so much daraghob! Relieved now I'm not the only one
Theresa_3825 — 14/06/16
Sophie, that's for part (i), we're talking about part (ii) 😊
No11 — 14/06/16
Did anyone get the second part of quest one with the group of 6 numbers where it told you the mean median and range ?
No11 — 14/06/16
*question
Elisha447 — 14/06/16
Yeah I did!! I think I got 37 and 7 I can't fully remember it was 30 something anyways
No11 — 14/06/16
Cool I couldn't get it I spend like 15 mins at the end but then I just left it Do you get the question about the rectangle where the length was 7 and the W was y
Max Gsamelov — 14/06/16
For showing the data on the graph for 2005 and 2015, did u have to draw a graph or could you use the printed on the next page
Michelle Uwakk — 14/06/16
Paper 2 was not perfectly ok and way easier than Paper 1
Johnobrien2k13 — 14/06/16
i did like 2 histograms stuck together so it was like a load of bars stuck together with the intervals on the bottom and matching up 2015 and 2005 for each interval. i thought you couldnt do a bar chart because it was continuous data?
Johnobrien2k13 — 14/06/16
i think stem and leaf was what we were meant to do tho
