Math Portfolio HL- Type 1 INVESTIGATINGRATIOS OF AREAS AND VOLUMES The purpose of this portfolio is to investigate the ratios of areas and volumes when a function y= xn is graphed between two arbitrary parameters x=a and x=b such that a‹b. Task 1 The general formula to find area A is [pic] The general formula to find area B is [pic] Therefore‚ the ratio of Area A to Area B is- = [pic] ÷ [pic] = [pic] × [pic] = n : 1 n:1 is the general conjecture formed. The given

Must you assume that the blood glucose levels are normally distributed to answer parts (a) and (b)? Explain your answer. Ans: a . Approximately normally distributed with mean 4.60 and standard deviation 0.021. b . Approximately normally distributed with mean 4.60 and standard deviation 0.015. c .
