what'd u do?

Can’t remember entirely but divided the Insurance tax (whatever it was called) by 20%. Added in the value of the insurance tax to my answer. Took the national insurance value from by number. Multiplied this value by 13.25%.

This method is so confusing but it’s all I can remember, sorry

multiply the frequency desity by the class width for all the boxes to find the frequency. than add it together. those were the poeple who had completed it. do the number of people who started it minus number for people who finished it (total frequency)

did that and somehow still got 8 - must've been some stupid error in the adding

answers i got:

x = -6
ben
guy got a decimal of a spin
x = -2.5 / -4.5 (for the function)
ratio was 6:10 (3:5)
bearing was 234
cube i cant remember but max was like a prism shape and min would be the 2 shapes literally put together (so volume for max) (area+area for min)
enlargement of -1/2 at (7,4)
hedgehog was 1,000,000 * 0.96^5 (i rounded up cuz it was closer)
he got home at 14:28 (so yes)

cant remember any else, u can jus reply with a question and hopefully itll come back to me :smile:

I think I got all the same except I said he won’t make it back on time and I got 2.46, but I think I messed up with the last calculation ?

I’ve been told before that they won’t deduct any marks if you round up or down, as long as you don’t put a decimal

its definitely 28, not to worry, it was only 2 marks, you won't be affected that badly

I got 612
Cos I did 80-25 =55 so 55 degrees equals 132 people then I divided 132 by 55 to find how many people 1 degree is then multiplied this by 255 (the Saturday angle)

I did and I explicitly wrote that you can’t have a decimal worth of a hedgehog

oh i did that but i multiplied it by 225 instead of 255 accidentally so hopefully i will only lose 1 mark

What did people get for the minimum amount of cubes question? It was the only one I struggled with, but I ended up with like 120. Any method for it?

Ben spun red the most times so his estimate will not be correct because the spinner is biased to green not red

Edit nvmmm Ben is the guy who spun the spinner the most times so his estimate will be the most correct so you are right
