84-79.5 here hah
You'll get one mark for showing it's at 50%


yeah, i saw this question i was like "how the f*ck are we meant to know where the average life expectancy is?!" so i drew a random line on the graph (in pen.. bad mistake) then skipped it. came back to it later i still wasn't entirely sure so i did it at 500,00 (i think it was?) but the other line i had drawn was right in the middle of it so i found it hard to read the values hahaha, so 1 method mark would be a victory for me. at least at got the HW Q right...

i am still sure the ratio of one to one to one to one is right. genders are different phenotypes.

I think it'll be a range, because it definitely wasn't on 80
I got HW wrong
Yeah you MAY be right who knows haha

Could anyone tell me if this is right?
240/300 UMS for an A, 60 UMS in EMPA (I'm confident that I got 55+), if I got a C in this (worst case scenario, 60 UMS)-
it would still be possible to get an A through absolutely smashing unit 5? (over 125/140?)
Thanks :smile:
