Can anyone tell me if I did this right for the India percentage question:

For the India question I did 17+20=37 and then 37 plus the original 20 = 57 to get the final answer. Is that right?

i just pulled a figure out of the air for population, increased it and found the percentage increase. i got something like 40.5

apparently qu 18 was 23'degrees (my friend is a maths genius) and 34.5 is wrong :smile:

India question was 40.4% I think
Polygon question had 10 sides
Q18 was 23 but I got 34.5 :frown:

I can't remember the lower bound question but I think you get the start number ?.88 then get the lower bound ?. 875 the cube root that , square what you get and times it by 6
Any one else get that

I got everything except not too sure on the probability ones if anyone can remember? And i got the polygon wrong but picked up 2 or 3 for working! Also got q18 right but only after some very shady working so may have lost one or 2 there! I think im probably looking at 90ish which isnt great seeing as 4H will be so much harder!

For the scale factor of the area did you have to use scale factor 4 or 5.
Was the answer 50 or 32?

Does anyone know what the question on the hemispehere was asking? Was in the surface area of the water's surface or the surface area OF the water? And everyone has done their exams by now I'm sure.

I got 50 as well because u need to times by 5 squared.
