whos ready for tomorrow! -->

how are u guys like 100% getting ready like ticking off the syllabus points and being confident besides just doing past papers

hii guys r there any formulas or rules I should memorise that wont be on formula sheet?

 

[suckmytoes55]

hi guys what conversions do we need to know, e.g I know that 1m cubed = 1kL but that's about it

Go through ur textbook

I predict that there will be 50% year 6 questions (like always)

guys ive barely practised non linear relationships, Ik the basics but that's abt it. its barely assessed no?

id say go over it for multiple choice they may ask a question

hey so u guys know why sometimes for normal distribution, we have to minus 0.5???, could someone explain and maybe indicate when i need to do this pleaseeee

um yes
so the questions they ask are like WHAT IS THE PROBABILIU FROM 0-whatever.... u take away .5 bc .5 is below the mean, hence bellow 0? idk if that makes sense I hope it does

For normal distribution, you always assume 50% of the data is lower than the mean and 50% is above the mean. Remember the mean is considered to have a z-score of 0.

The table tells us that as the z-score increases, so do the percentage of scores covered.

Since the question is asking what is the probability for selecting a scores between 0 and 1.94, and knowing 0.9738 of the data has a z-score of either 1.94 or lower; subtracting 0.5 takes away all the z-scores below the mean.

thank uuuuuu

this might be a stupid question but just confirming, its possible to use both sine rule and cosine rule right for a question if you have the required information?

like both would work right?

bc sine rule is: ASA and SSA
and cosine rule is: SSS, SAS


SSA is the same as SAS, so both sine and cos would work for a specific question that has SSA.


am I trippin?

you should be fine, ive used sine when they did cosine and i got the same answer, dw

so basically if it says from 0-whatver then u minus 0.5 but if it gives a number and says probaility of more than that number then u minus by 1 right???
