The graph gives data on the percentage of students who worked less than 15 hours a week from 2000 to 2009. What type of correlation coefficient will you obtain for this graph?

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

answer: (3,11) is your answer.
