- 3/50 = 0.06
-2/9 = 0.2 recurring
-the mixed number addition, not sure but i got 1 and a 1/2
-the loci and construction question-->put compass from C 5cm away and draw an arc, then do a line in middle between AB and AD i think , and shade bottom left section??
-probability tree, fill in remaining fraction over 10 (e.g 2/10 and 8/10)
-then probability of 2 no faults, it was 0.9 multiplied by 0.8 which was 0.72
-the drawing a plan question - should of got an 'L' shape (3 vertical, 1 horizontal)
-on isometric shape, should have drawn a 3 by 2 cuboid
-smallest surface area of cuboid shape was 22cm^2
-question with formula linking height of dropping a ball of a cliff to sea or something, u had to write the height of something, i'm not sure but i put '90m'
-work out t and h values for histogram, should have got like 90..70..45
-then plot that correctly and draw a line through the points so you get a curve going downwards
-the drinks ratio (3:1), should have been like 750 ml of apple juice and 250ml mango juice
- a question on profit a girl made from drinks should have got something like £32.60
-inequality question = X greater than/same as 2
-on inequality line draw a filled in circle on 2
-vector question, for p + q, you literally added the column vector thingss
-vector question k=? and j=?
-2nd from last question, i got 17 + a surd number..
-last question i got 7x something with plus or minus something, cant remember on top part and got like (x-2)(x+3) or something like that in brackets on the bottom

thats all i can remember atm, there was also a question about runners in a 10km race, then u had to work out whether a prediction was correct or something...
For the vector question, j=3 and k=2. The two questions before we're 3p = 9/-1 and p+q= 1/1. The prediction question should have been no, but I didn't put that.
The surd questions at the end I got 1/27, 17 + 8 square root 2 (I think; it's so hard to remember!!) and last question, I got 7x-1 on the top and the brackets on the bottom.
All I remember now! I'm sure we've all done fine!!

The question where the girl was going to mix the drinks apple juice to mango juice was 3:1 and the answer correctly should of had been 750:250 because you had to do 1000 (which makes up 1litre) divided by 4 (the ratio added up) to get 250.
250 x 3 = 750.
250 x 1 = 250.
This question was worth 3 marks.

The football question which was question 6 was something like East Hill have a total of 28 points.
3 points means a win and 1 point means a draw.
Find out how many of the 12 matches East Hill has won.
This question was worth 4 marks I think.

The values for the y = mx + c line was 90 - 70 - 45 and that was worth 2 marks.
Drawing the graph on with them figures and I think a smooth curve would of had gotten you the other 2 marks.
3. Re: 11th June OCR Maths Higher Tier New Spec
if anyone could remind me of what the completing the square question was I should be able to answer that gladly.
4. Re: 11th June OCR Maths Higher Tier New Spec
I can recall that:
question one a was the finding the fraction 3/50 as a decimal worth 1 mark.
question one b was putting a fraction 2/9 as a decimal and it was a recurring decimal worth 1 mark.
question one c which was the powers question was 2 marks the answer gave 5 to the power 3 I think.
question one d was the mixed fractions question which was 1 mark I think.

question 2 was the loci question where you had to bisect the perpendicular line and then measure 5cm on your ruler away from C which was worth 4 marks.

For this question I got the answer 9, what about you lot?

i think the completing square question answer was something like (x+4)^2 -16+10

wasn't it? or something similiar??

no they won 8 matches..(and drew 4)
because if you do 8x3=24 and then 4x1=4 and then 24+4=28
8. Re: 11th June OCR Maths Higher Tier New Spec
okay updated with other peoples answers, feel free to check:

- 3/50 = 0.06
-2/9 = 0.2 recurring
-the question with adding&subtracting powers, you should have got 5^3, but then i multiplied it out to 125?
-the mixed number addition, not sure but i got 1 and a 1/2
-the loci and construction question-->put compass from C 5cm away and draw an arc, then do a line in middle between AB and AD i think , and shade bottom left section??
-there was a probability question where you had to work out probability from a table, can't remember but i got something like 0.4?
-probability tree, fill in remaining fraction over 10 (e.g 2/10 and 8/10)
-then probability of 2 no faults, it was 0.9 multiplied by 0.8 which was 0.72
-the drawing a plan question - should of got an 'L' shape (3 vertical, 1 horizontal)
-on isometric shape, should have drawn a 3 by 2 cuboid

-the drinks ratio (3:1), should have been like 750 ml of apple juice and 250ml mango juice
- a question on profit a girl made from drinks should have got something like £32.60
-football question about how many times they won out of 12 matches, answer = 8.
-inequality question = X greater than/same as 2
-on inequality line draw a filled in circle on 2
-completing the square question=(x+4)^2 -16 + 10, so (x+4)^2 -6
-vector question:3p=9/-1 and for p + q= 1/1
-vector question k=2 and j=3
-3rd from last question it was like 1/27 apparently
-2nd from last question, i got 17 + 8 to the square root of 2
-last question i got 7x something with plus or minus something, cant remember on top part and got like (x-2)(x+3) or something like that in brackets on the bottom
-inverse proportionality question, i did wrong, what did people put for k?
-prediction question on 10km race??
9. Re: 11th June OCR Maths Higher Tier New Spec
and what did people get for the minimum value underneath the completing square question?
10. Re: 11th June OCR Maths Higher Tier New Spec
I got -6
Also for the histogram question I got 36 people and for the next question that her results were higher than the national survey. Ring any bells?

i didnt put anything for the minimum value but yeah, i remember i got 36 people for the histogram question too and that her results were higher too. what did u get for the inverse proportionality questions?
12. Re: 11th June OCR Maths Higher Tier New Spec
I remember getting k=18,000 and then for the next question I got 450 hertz. That's all I can remember, was there another?

The next part of the question where you had to compare the results to the national survey's 54% was worth 4 marks, if memory calls.

I think what you had to do was to actually find out the percentage of people who worked between 30 - 45 hours per week (or whatever it was). It then comes out to be exactly 70% - so her results were higher.
14. Re: 11th June OCR Maths Higher Tier New Spec
I didn't do this paper but i did an OCR paper yesterday as well (calculator) applications of maths paper 1
a TV guide has 2/3 pages on reviews
5/6 pages are on photos
and the remaining 6 pages were on index
how many pages were there in total? (4)

108 pages

6 pages were index - which is the remaining 1/6 left. This means there are 36 pages used for pages for photos + index.

These 36 pages are the remaining pages when 2/3 of the magazine were for reviews. So, 36 pages is 1/3 of the whole magazine.

36 x 3 = 108

Can you remember what the first part of this question was? or how many marks it was?

36 x 3 = 108
****!, i got 15.
6 x 2/3 = 4
6 x 5/6 = 5
plus the 6 = 15

so many in my year got different answers!

Yeah that's how I remember it too!
19. Re: 11th June OCR Maths Higher Tier New Spec
Good Luck for the maths exam tomorrow everyone!
20. Re: 11th June OCR Maths Higher Tier New Spec
For number 2a) Was the answer 5^3 or 125? I know they're the same thing, but did it matter?
