Equation for the quadratic graph translation: y=(x-2)^2
Counters 116 and 84
Ran 120 meters
0.1 probability for the histogram choosing 130kg?
Value of p = 6
Value of R = -4
3^x exponential graph going from top right to top left never touching the x axis
Ermmmmm can't remember any others
Numerator of the simplifying algebraic fraction was like 9x + 7 or 7x+9
Ratio 2:3 men to women or vice versa

Bro a lot of people didn't put 120 in my school it was a badly worded question -- along as you attempted to find the LCM of 3 and 4 you'll get at least a mark

17. What did you guys put for the question about mean amount of kids in a secondary school or primary? I put 200 no idea if it's right

i put 121 because i though that 120 would be when they were at the same place and 121 was when they overtook each other.
