you've saved my core maths exams!!!!
I came here looking for videos on how to use PCP but now i am educated on PMCC!! great work chief
Do you have the core maths 2019 paper 2a, can you please go through the answers to those questions
For the last question, the regression line equation formula is y=a+bx... so why did you do y=bx-a to workout the actual adult height
the value of 'a' was negative( -136), so y=-136+1.84x or y= 1.84x-136....... i prefer the second version as its looks neater :-) but either is fine. Does that answer your question?
Yes, thank you.
Thank you for this.
where does 165 come from?
Hi, it the value you are given in the question (12:22)
