sorry?!Does anyone have a scan of the exam paper?
sorry?!Does anyone have a scan of the exam paper?
that question was so much waffle and for what justification I wasn't sure if they wanted a real life answer of just a maths answer so I put something like if you extrapolate the line, you would get to negative energy consumption (impossible) and in the summer it may rise again due to the use of air con lolwhat did u guys get for the regression line equation and the justification
i'm so impressed u can remember all the numbers :0y = -10.4x + 236
Justification - You get negative energy output at 23*, so it doesnt work at higher temps
Yes I did that thought it didn’t seem right but maybe it wasWas the trig Q with (θ-60) like -60, something else & 300??
If only I could memorise essays....i'm so impressed u can remember all the numbers :0
I said 23° is outside the data set so is not possible but saying it’s negative is also truey = -10.4x + 236
Justification - You get negative energy output at 23*, so it doesnt work at higher temps
i got -4 < m < 7/6For finding the values of m for the gradient which would intersect one of the graphs, did anyone get -4<m<4
low b6, high b5 probablyWhat do you guys recon a 70 will scale to
What do u recon u got raw marklow b6, high b5 probably
a 74 last year scaled to 90, so idk (given that todays test was harder than 2022)
Harder than 2020 and 2022 but imo 2021 was harderGuys is it me or was that exam much harder than 2021 2022 and 2020??? Or am I just dumb
mid to low 90's maybe? high 80's at worstWhat do u recon u got raw mark
Isn’t c positive cuz it’s a double root in the positive zoneoh no like the -(x-b)(x-c)^2 and b>0, c <0
Not true. 74 was 2021. 79 scaled last yearlow b6, high b5 probably
a 74 last year scaled to 90, so idk (given that todays test was harder than 2022)
121.52 iirc,whatever it was, I rounded down cuz adding an extra cent would not give 100 withdrawalsWhat did u guys get for the M value for the withdrawal question
(3, -24) i thinkWhat did you guys get for the points of R
i got (3, -22)(3, -24) i think
