(i) Work out how many of the 225 students
you think will want to go to the Theme Park.
(ii) Which of the following statements will make your
answer to part (i) less accurate?
A : Ask a bigger sample than 30
B :Ask only Year 7 students
C : Ask only people in the cafeteria
D : Make sure the sample is randomly chosen

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

here's a poem i finished a while ago. i hope you like it and that it inspires you.
