[@safidhaider301]

Dude u made me tear up cuz the amount of time and memories that is gonna be stuck with us..the efforts the sleepless nights just to score good marks those late night texts and studying damn bruh nostalgic

[@pranavappalsawmy3214]

That`s was very helpful but their I saw a mistake which is in the Qu 2b) the modal class should be 110

[@OALevelMathematics]

Yup. Addressed in the comments below

[@tasnimnuha2065]

Thanks sir for your generosity. Doing maths with you is a lot fun.i used to hate doing maths. Once I came across your page, I overcame my anxiety.

[@jawaidzafar1540]

These videos are really really helpful... I was so stuck but I have found my way..... You are LIFE SAVOUR SIR!!! THANK YOU 💕

[@pxlPF7786]

can someone explain why did we add +1 at @8:36

[@10tenshd]

34:06 why did you multiply 3/8 with 3/8?? Why can't we just add them??

[@OALevelMathematics]

Monday "AND" Tuesday. Whenever we have "AND" - multiply

[@10tenshd]

@@OALevelMathematics tysm!

[@amnawasti2012]

Shouldn't the modal class in Q2 (d) (ii) be 110

[@OALevelMathematics]

Yup, address in the comments below.

[@emmajayasundera6990]

32:49 why do u take 62.5 as the time. They have asked for the upper bounds in that question, so why do we take the lower bound of time instead of 67.5??

[@hanako5158]

because the sir said that we need to calculate the max speed by dividing the max distance (upper bound) with the lowest time (lower bound) so yeah!

[@nadeemjabla]

Thanks so much for the effort u put into your videos !! You’re amazing

[@itsdharun]

Oh my god....... this vedio was super useful for me, pls make more vedios from more papers please.... ur work is highly appreciated.....

hello sir, i am really confused in Question # 8 part (b), can you please explain it or direct me to your any other video where i can understand it more thoroughly🙂

[@dur-e-fishanfatima570]

watch zainematics video of graphs of function.....i also had the same problem but that video helped a lot

[@MurtazaJavaid-b7l]

Your method is difficult buts thanks❤

[@tigerman3326]

Teacher U made a mistake on question no 2 (d)(ii) it's 110 < m > 120 the modal class not 120 < m > 130.

[@OALevelMathematics]

Thanks for commenting

[@tigerman3326]

You're welcome teacher

[@blissssketchbook49]

32:49 why did you not take the upper bound of the time and only of the distance?

[@OALevelMathematics]

Answer: Speed = Distance / Time. To find Max Speed, we need to take max dis / min time

[@dur-e-fishanfatima570]

hello sir...i wanted to ask how can we tell that whether the masses are consistent through interquartile range? love from Pakistan

[@Jibrail5726]

The lower the interquartile range is , the more consistent the mass is as there is little difference b/w the masses

[@mishalshaikh8506]

Thank Youuu!! Can u plz explain that in Question 9 part (d), how can u just assume that angle MEF= 90*. However from the info given, we can just infer that angle AEF= 90?

[@OALevelMathematics]

This is because M and E are points on the horizontal plane and F is vertical above E. Using some imagination, you can conclude that MEF is 90

[@mustafaabbasi3649]

In question 4 part c why did we multiplied 3 upon 8 2 times? Instead of multiplying 3 upon 8 and 2 upon 7 anyone please tell me.

[@ajwadlahin7862]

34:11 why did you subtract 5/8 ?

[@areejabrar8738]

ivfygdgg

[@nadeemjabla]

because 5/8 was the probability of arriving ON TIME but the question asks for probability of arriving LATE if you’re confused about why we subtracted it from one it’s because 1 is the total probability of anything happening so anything minus 1 would be the probability of that thing *not* happening hope this helps

[@ranudadela3253]

this is really helpfully

[@cr7series741]

U HAVE DONE THE Q2 PART D 2 WRONG THERE SHOULD BE 110

[@juliaattiave7054]

Sir in quest 1 part c why 1 is added??? I am confused please reply urgently

[@OALevelMathematics]

This is because I am adding the Ps together. We 1P + 0.105P = 1.105P

[@UnderJestice]

Sir num 8(c) can we use simultaneous. I got same answers but would i get any marks?

[@anoran.7505]

You could check the marking scheme 🤔

[@zekron4580]

sir question 2 part d part two should be 110 to 120 right

[@shahjahankhan25]

I couldn't understand the principle of finding the midpoint of AB in Q9 part : d..

[@AminaSarfraz724]

20:21 isnt the model class 110-120

[@OALevelMathematics]

Yup. Addressed in the comments below

[@bilalahmedshariff5576]

Sir, this is very helpful, but sir in q9(a) why did we assume that

[@zhongli9356]

if you look, the triangle ABC is a right angle triangle, because the sides AB and BC are straight (ABC is the half of a rectangle, look at diagonals)

[@krishakrishna4484]

For 5)c) why does the shaded area region get divided by area of a circle and not another shape ?

[@MoonchildDaz]

Bcz this part asked to calculate the % of area of the 'circle' that is shaded

[@thefearlessone-lintrepide5022]

When it says km/h we need to divide by 60 but what if it says km/m? I'm actually a bit confused about this.

[@OALevelMathematics]

Km/min - this means how many Km does the object travels in 1 min for example, a car travels 20km in 10 mins. So, the speed in km/min is 2km/min (20 divide by 10)

[@thefearlessone-lintrepide5022]

Qu 4 c) how is p(late) = 1 - 5/8 = 3/8?

[@OALevelMathematics]

early is 5/8, so late would be 1 - early = 3/8

[@muhammadtaha2456]

Sir what if we have to lower bound of time will we take upper bound of speed and lower bound of distance? To find the lower bound of time.

[@OALevelMathematics]

YES!. since time = distance / speed. To find lower bound of time, you take lower bound of distance and upper bound of speed

[@painlzzz4026]

excuse me sir i did not understand qs 8 part b ,finding the gradient can u pls help me

[@OALevelMathematics]

There is a concept behind this. Gradient of Perpendicular x Gradient of L = -1. so I will have 1/2 x Gradient of L = -1. So Gradient of L = -2

[@OALevelMathematics]

To begin, we have observe the diagram. ME is not even on the line AB [so, that rules out 1/2 of AB]. We observe that ME is in the same direction as BC [BC is 4.3]. Since E is the centre, we realise that ME is will be 1/2 of BC = 2.15. Hope this helps.
