it was okay like and opinions ?

Orlamariaflanagan
BEST THEOREM EVER

davidogrady
lol ya was certain it was pythagoras before it all

sorecauvanesa
I only learned theorems 19 and 14 so I didn't know how to structure it

Elisha447
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
I did a bar chart and put each similar bars beside each other like they do in some questions from the paperes

Ooooooooo
Would a line and plot graph be ok?

jackkfleming
ya

Elisha447
Does anyone know if a histogram was okay??

davidogrady
i did a histogram aswell ,twill be grand

Elisha447
Ok Thanks :)

davidogrady
was that a simultaneous equation towards the end or not ?

Ooooooooo
Yeah it was a simultaneous equation

davidogrady
oh god

Liam_4376
how did you do the area of a circle touching the triangle points?

davidogrady
what did ye get as an answer

Ooooooooo
X=3 and y=1

davidogrady
oh okay

mathswhiz101
the hypothenuse of the triangle was the diameter of the circle

mathswhiz101
Ye should all be studying for CSPE .....

davidogrady
yes exactly

Whitestar
fcuk the paper

Emma_5811
Terrible didnt have a clue

xroisinx
was a stem and leaf graph okay for showing the 2015 and 2005 information?

SryanBruen
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
What was the area of the circle, anyone get 61 over 4 pi cm2

annie1996
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
@cmck134 Yeah Im pretty sure I got that

ug_roland2504
the bigger box sides were 2 units
the smaller box sides were 1unit
it was in the question

SryanBruen
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
i got 28 units squared for that question

darraghob
are 2 pie charts ok for the graph question?

mazink0204
Steam bruen calls it easy, then gets a c

SryanBruen
I will not get a C ya weirdo.

annie1996
Or the question on coordinate geometry where they asked about the circle ? Like what was that ? 😂

Gift_3466
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
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
For b wasn't it 12 x 7?? Because it was the same as a ? Maybe not 😂

Theresa_3825
I got 12 x 7 for one of them. I can't remember which side was what letter 😃

Gift_3466
Ohh, I thought the two were separate shapes all together. Well thanks for the explanation

Theresa_3825
So did I. I only realised 10 minutes before the exam was over 😂

Gift_3466
Did you ever get an answer for the cubes and right angle triangle question??

Theresa_3825
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
Okay I won't, I just hope I did well enough anyway

Aimeedonaghey01
Was a stem and leaf diagram okay?

SryanBruen
Am I the only one here who did a Trend / Line graph for that question?

Aimeedonaghey01
I know a couple who did it so I say you're fine

Aimeedonaghey01
People*

needhelp101
WENT ABSOLUTELY HORRIFIC. theorem 19 and 14 both didnt come up at all. Failed it.

EH458
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
I think I did perfectly fine in paper 2, went smoothly enough I think 💁🏼

Suitcasey114
Did anyone else do a bar chart,for the female members of parliament?

Andrew_7539
Did anyone do a stem and Leaf diagram

SryanBruen
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
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
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
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
I'm starting to see it now,but I still think stem and leaf would have been best

SryanBruen
Yeah I'm not looking for an A bro haha. I'm looking for a B.

SryanBruen
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 stemandleaf display is a device for presenting quantitative data in a GRAPHICAL format".
I hope this answer your question

Theresa_3825
Would 2 separate histograms be okay? I used the frequency table.

SryanBruen
Yes it would be acceptable

needhelp101
What if you used one histograms but put them both on it ?

ug_roland2504
if you do 2 histograms you are not really comparing them. You are just showing each graphically as individuals not in a comparison.

Blathnaiddoolan
What did you get for question 12 (b) (i)???

SryanBruen
My workings out of that Blathnaiddoolan
Soh, Cah, Toa?
I just used Tan (though it's not a rightangled triangle....)
Tan 70 degrees = x/7
7 Tan 70 degrees = x
19.23cm = x
I probably did it wrong LOL

ug_roland2504
it was something like 10.23

SryanBruen
Can u show me how u got that? ^ Like see how I got mine

sethreed
you had to spilt the isosceles triangle into two to get two right angled triangles

Fiddlestix
Guys anyone do pie chart ?? So worried!

Blathnaiddoolan
Thank you what about 7(b) 8(c) and 5(a) ???

Theresa_3825
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
Yeah I got that for 5a.

Blathnaiddoolan
Yeah I got all of that aswell

Kagalwala
For 7(b) I said the angle in a semi circle is 90 degrees which is why y is 90.

darraghob
Yah fiddlestix I did two pie charts for the graph question

Theresa_3825
Kagalwala, I think that might be okay too. I mentioned that AC was the diameter too because why not 😂

sophie544
The answer for that question was 80 degrees as it was a cyclic quadrilateral and opposite angles sum up to 180 degress

Fiddlestix
Thank you so much for letting me know! Relieved daraghob!

Fiddlestix
Thank you so much daraghob! Relieved now I'm not the only one

Theresa_3825
Sophie, that's for part (i), we're talking about part (ii) 😊

No11
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
*question

Elisha447
Yeah I did!! I think I got 37 and 7 I can't fully remember it was 30 something anyways

No11
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
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
Paper 2 was not perfectly ok and way easier than Paper 1

Johnobrien2k13
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
i think stem and leaf was what we were meant to do tho
