feeling excited, confident, and nervous. all in one emotionwhos ready for tomorrow! -->
yeah same, and i want it all to be overfeeling excited, confident, and nervous. all in one emotion
not ready for the exam but ready to be done with math foreverwhos ready for tomorrow! -->
Go through ur textbookhi guys what conversions do we need to know, e.g I know that 1m cubed = 1kL but that's about it
id say go over it for multiple choice they may ask a questionguys ive barely practised non linear relationships, Ik the basics but that's abt it. its barely assessed no?
um yeshey 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

thank uuuuuuView attachment 45080
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.
you should be fine, ive used sine when they did cosine and i got the same answer, dwthis 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?

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???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
Ik I got cooked for the last 2 question and the other trig where you had to find CD. Surely a 80 scales good rightttHOWD WE GO GUYS?!!??? I HONESTLY LIKED IT BUT SIMILAR TO 2020
