omg yessssss! DIEEEEEEEEEEEEEEEEEEEEEE ;'(Was anyone silly like me and forget to do a negative gradient on the back page? making the formula $=-4000n+60000

I got 925 (d) ii) the interquartile range for females
8,9,11,11,12,15, - 11+11 divided by 2 = 11 16,18 ,18,18,20,21,27,34 - 20+21 divided by 2 = 20.5
Interquartile ranger = upper - lower
= 20.5 - 11
9.5
Did anyone else get this?
it was A lol...kiddo, you do know for 12 that you had to flip the equation on one side ( the right side) then cross multiple. Thus the answer was D.
There was a question almost exactly the same as this in last years paper, the answer is A here is my workingkiddo, you do know for 12 that you had to flip the equation on one side ( the right side) then cross multiple. Thus the answer was D.
+1I 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)
I got that as well, I'm pretty sure it is correct.financial expectation using the 2 spinners, i more than likely got it wrong since i got -$1.50
omg yessssss! DIEEEEEEEEEEEEEEEEEEEEEE ;'(
I got distance = 30,048km (Nearest Km)[Using the arc length formula)What did anyone get for Q27 bi, the one about the longitude and latitude of Rabaul?
same, i think 9 was the correct answer as you dont include the median.yay i got 9 too
Yes but I've made way too many one-marker mistakes and they all add up! GAH I hate maths!We're both lucky it was only a 1 marker then
i got 4 degrees south, but degrees west i got wrong i thinkWhat did anyone get for Q27 bi, the one about the longitude and latitude of Rabaul?
It was 4degSouth, 152degree's east, because, if jarvis island is 160deg West, And Rabaul was another 48deg west again, after it goes past 180deg west it starts turning into east because theirs only 180 degrees in both east and west, if that makes sense?What did anyone get for Q27 bi, the one about the longitude and latitude of Rabaul?
YAYAYE, got 2 marks for the distance thanI got distance = 30,048km (Nearest Km)[Using the arc length formula)
And for b)ii) I got 4*South and 208*West
isnt the maximum longitude 180 degree, east or west? For that question i calculate 208 West would move into East territory if u know wat i mean. So i did (208 - 180) and then minus that off 180 degree east, which gave me 152 degree east.I got distance = 30,048km (Nearest Km)[Using the arc length formula)
And for b)ii) I got 4*South and 208*West
yeahhh i had a feeling i got that one wrong, hopefully i still get 1/2isnt the maximum longitude 180 degree, east or west? For that question i calculate 208 West would move into East territory if u know wat i mean. So i did (208 - 180) and then minus that off 180 degree east, which gave me 152 degree east.

Exactly what i just saidisnt the maximum longitude 180 degree, east or west? For that question i calculate 208 West would move into East territory if u know wat i mean. So i did (208 - 180) and then minus that off 180 degree east, which gave me 152 degree east.
