0-3, 4-7, 8-11, >11 ?

Question 4c is actually 2k^6

Original post by NancyMassingham

Question 4c is actually 2k^6

That's only when the there is a number bigger than an 1 in front of k, for example:

(3k)^2 = 9k^2

No because there is no single option for 0

Original post by NancyMassingham

Question 4c is actually 2k^6

The question was (k^3)^2 Which can be wrote as (1k^2)^6 which is just k^6

Didn't the question say "never"? I'm not sure though.

It doesn't need to be a single option, as long as there is an option.

There does have to be because if somebody has no bags of crisp then they cannot put it in an option that says 0-3 because you won't know if they are having none or not

You don't need exact values, just a range of values because a questionnaire is used to gather a consensus of whatever the topic is.

On every past paper I've done, if there is no single option for 0 it is classed as wrong according to the mark schemes.

Oh, don't get me wrong. Im not saying having a single option for 0 is wrong because that's completely fine. I'm saying it's just as acceptable to include an option for 0 in a range.

Yes you are correct

Ohh okay, thanks for letting me know

I may be wrong, but wasn't the expand and simplify 2 marks and the simple factorisation only 1 mark?

Spoiler

for the circle and square areas, if i wrote 100 - 25pi in my working out clearly but put 75pi in the answer box, would I still drop a mark?
