does anyone know what the question was for (I think) it was question 8. People have said the answer was 60? It's the question that was above the letter one.

No, that's not how surds work. You can't simplify root six because no square numbers can come out of it.

Oh god yea I'm so annoyed at myself for that now I don't know what I was thinking!

You may want to edit the image for the last question so as not to mislead people.

AD = AB is not right.

Fixed it, thank you.

I read -1.6 and 4.6 😪. Do I get 0 or is there range?

It just said work out the x values. :smile:

I don't remember it saying that. Did it not just say to estimate simultaneous equation solutions. Oh well, I doubt I'd lose marks because its positive marking and I got my x-values correct!

Don't worry, you'll probably still get 2 marks out of the 3. :P And it's much better than most people managed to get in that question. :smile:

I'm pretty sure the answer was 7x10^8

the 10^3 was divide 10^-6 so indices rules are divide means -: so 3--6=9

Nope, just the x ones! Yeah, no harm in putting the y values as well. :tongue:

1) volume of a prism: 750cm3
Q??) probability: 0.95, 0.05, 0.7, 0.3
Q2) questionnaire, question doesn't specify time, ambiguous and also the options aren't specific enough "often" "sometimes" hard to interpret
Q??) 36%- rent increase
Q??) circle theorem: angle 69 degrees
Q??) not enough tiles, 7.5 litres, needs 10
Q??) inverse proportion: 100, 25, 4
Q??) circle in a square- 100-25 pie
Q??)11 female teachers
Q??) box plot distribution: comment on mean, range, interquartile range with numerical comparisons
Q??) 90 teachers
Q??) estimate L, in sample of 300, round 80 to 100, 16 to 20, so estimate of 60
Q??) powers/indices, add the powers when multiplying two numbers, take away powers when dividing, and if in a bracket, multiply those powers
Q??) vectors, a) a+b, b) 3b-a, c) 3/4 a + 3/4b (can't remember whether + or -)
Q??) factorise n2 -7n = n(7-n)

Thanks. Can you also remove the attached image from that post - it hasn't been corrected.

My predicted A* now feels like a B if i'm lucky. Had a panic attack in the exam and they refused to let me go and come back (even though people were going to the loo) and i just cried all over my paper. Yay.

You had to divide 3.5 by 5, leaving you with 0.7x10^9 = 7x10^8.

How high do you think the grade boundaries will be?

Q22 was 78 not 69

Could anyone tell me how to do the quadratic equation question? I kind of messed it up.

I plotted the line at +2 instead of -2 and +6 instead of -6. So I think that'd get me 0/3.
For the simultaneous equation, I correctly plotted x+y = 6 but since my answer to part (a) was wrong, would I get just 1 mark or would I get more as it is dependent on the previous part and I did the method correctly?

Much appreciated. x

the last question said your answer must be in numbers in cm?
