I remember the 0.5 and -0.5 the -33 but I can't remember what I put for the last one. Either -6 or -4
Yep- it was -6, -33 :smile:
Very good exam, the one that troubled me the most was the bearings one but i mangaee to get it after figuring out it was the sine rule. Last question was definitely x = 0.5 and x = -6 while y = -0.5 and y = -33

Percentage question i got 1.7%

Pineapples was recipe B as i did pineapple divided by total juice and multiplied by 100

Compound interest questions i got £3860 and year 2020

X = -8.5 on the question where you had to multiply the fraction out

Yeah i got 175 and then something on decimal as well, but 175km is perfectly fine

Think i got 55 and 124 but the decimal points of both added the answer to 180 degrees, so realistically 55 and 125

Something like 55° and 124.9° :smile:

For the pineapples you divided each pineapple juice that can be made by the total made?
Did you convert the litres into ml because If so I think that Recipe C was the highest resolution.

Yeah I got those. For the stem and leaf diagram I wrote about the mean and the range.
