well for the last question on the cal, you had to use the quadratic formula; x was 0.(somthing) and 1.(something) (sorry, i cant remember what it was)

What did you get for these questions?

To find the upper bound did you have to as 0.005 to the answer for that question on cars (I assumed that to find the upper bound you had to halve 0.01 since it was to two decimal places)?

For the 6 mark question on booking tickets, did you write yes or no?

Personally, I thought that paper 3 was harder but I found them both to be fine. What about you? :smile:

The answer to the last question on paper 4 was -1.1 and 0.5 :smile:

Is this for definite, or just a prediction?

i got the cubed root of 3 thing.
also i got -1.1 and 0.5.
for the cumulative frequency did you get 902mm of rain ?
for the cereal box i got offer A, and i also said he couldn't go on holiday unless Mr x went from a different airport.
i got the the child got 4 on his test.
and for the years for the population to reach 8000 i got 2025, because it took 15 years to get to something like 7800 or something, so 2010 + 15 =2025.

I will post other answers that i remember :smile:

Same here for all of those (apart from the top one because I had no idea)

What was the real way to do the moving average question? I used trial and error, but pretty sure that wasn't what you were supposed to do...

I put 2025 for the birds question but some people said it was 2024 because on the 1st jan 2024 the pop was like 8100 or something and 1st jan 2025 it was 7700, the question asked which year did they drop below 8000 which means they must have dropped below sometime in 2024
