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....)

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 ��

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

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.

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

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.

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

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

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.

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

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?
