hey, so basically when he does that it should be *-0.75Z* = 0.0975 and then -Z = 0.13, however Z cannot be negative so it has to be positive. Since he knew this from beforehand he left it as positive. Hope that helps!
@@streamerrizz its not -0.75 the equation is z=0.0975 +0.25z remember there's an invisible 1 infront of the z so its basically 1z=0.0975+0.25z now we just need to get all the z on one side so take away 0.25z on both sides 1z-0.25z=0.0975+0.25z -0.25z this simplifies down to 0.75z = 0.0975 which equals z=0.13
i have my test in 40 minutes, but can someone explain why in question 7a) he did not include gravity in the final equation? he did 0.6/1.4 rather than 0.6g/1.4 like it says a is = to
exam's in 3 hours and a half, good luck everyone.
thank you !! really helpful and enjoyable :))
That yawn caught me off guard LOL🤣
your amazing man thank you so much for this
41:46 cheers mate 👍
did you forget to x 9.8 at @51.42
Also for the first question could you also say that in c also how much hours the student studies/ prepares for the test and not just sleep
good video but it would be helpful if we could see the questions too
thank you so much for this!
was stuck on 3 b ii, ty
Sir, for question 4 part a, could you say to remove anomalous results? or would that be wrong
I love u
I was just wondering why at 12.22mins you can minus .25 and get .75 ?

@@streamerrizz its not -0.75
the equation is z=0.0975 +0.25z
remember there's an invisible 1 infront of the z so its basically
1z=0.0975+0.25z
now we just need to get all the z on one side so take away 0.25z on both sides
1z-0.25z=0.0975+0.25z -0.25z
this simplifies down to
0.75z = 0.0975
which equals
z=0.13
Can someone explain on 4b why you add 1
its cos you have to add it to the lower bound.
(LB + (place in group/group freq.) x CW)
what are grade boundaries liek for this
What kind of percentages are you getting on here?
A = 47.5
B = 40
C = 32.5
D = 25
E = 18
U = 0
Usually.
@@valedits453 wait no way, so for stats and mechanics together it's only 48 percent for an A. Or 48 out of 60😭
@@patatoe558 For me the paper is out of 80 so 48 out of 80 or for you it would probably be 36/60 around
@@patatoe558 and marks get rounded down as opposed to being rounded up in my school so actually 47/80

nvm he does but hes a jokeman cuz he didnt show him doing it and i didnt hear him mention it on 2x speed
@@monkeypeeler don't be rude you wasteman. If you wanna scrap me then just say that. Probably got an E anyway haha
@@humzino6630 no way are there people arguing on an AS level maths video

You look like Bruno Fernandes
