Q1) The domain was -1 to 1

Q2) A first one as it was the only sequence increasing

Q3) A I got A

Q4) The area of the segment you had to work out the radius from the equation of the circle and then use the formula and then use the area of a triangle to then subtract it to find the segment I think I got 16. Something

Q5 I think was proof by exhaustion

Q5)For the partial fractions I got 6 and 7.

Area of shaded region (within circle)- 16.8

Temperature question- 39.8

Normal Hypothesis test- 0.0345>0.025 โ> accept Ho

Finding mean and standard deviation- mean= 37.3 sigma=5.7

Last part of final question- 0.296

Stats multi choice I put moderate negative (wasn't sure how strong "stong" needed to be), and quota sampling. The by parts question A=4 B=7 I think (could have been the other way round). Then the integration that follow I got ln(81/16) + 7/6 i think
