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🤣
You look like Bruno Fernandes
🤣
your amazing man thank you so much for this
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
I love u
did you forget to x 9.8 at @51.42
good video but it would be helpful if we could see the questions too
Sir, for question 4 part a, could you say to remove anomalous results? or would that be wrong
thank you so much for this!
41:46 cheers mate 👍
What topics comes up the most in as level mechanics?
was stuck on 3 b ii, ty
I was just wondering why at 12.22mins you can minus .25 and get .75 ?

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
