Also, are you sure the translation wasn't in vector, (-2, -4) as I believe the top shape was transferred onto the bottom?

How many marks for the histogram question if you worked out the frequency density for every value, labelled the axis, but didn't actually draw the graph out of 3 would you get?

In question 14 c) is it possible to say that the expression is not prime because when we factorise it, niether factor is identical to itself?

For 14c are you meant to be talking about the values of t and then substituting a prime value in etc.

No problem. Okay, it looks like I did a decent job of the paper but found it SO hard! What was the question of Q12 part c) please?

And also, if I put for proof on the factorising one (part c) that because both brackets always multiplied to make even numbers so can't be prime, would I get the mark?

No. You are talking about the value of the quadratic expression and you shouldn't substitute anything in.

Are you telling me you can't convert 0.16 into a fraction?

\frac{16}{100}=?

I thought the length of the trapezium was 8. root 100 - root 36 = root 64?

12c) Work out the probability that this office worker took more than 40 mins to get to the office.

There were 50 office workers and 8 took more than 40 mins.


That answer for 14c) is wrong . The expression is NOT always even. If you substitute 1 into it you get 9 for example.

No idea what you did there. The answer is \sqrt{145}.
