.32=32% what makes this question easy is that there are 200 members so to convert the percents into accutall numbers so like .32=32%=64 people (since 200 is 2 times of 100)
A. fiction of 31-40 compared to 21-30 fiction 31-40=.38=38%=76 readers fiction 21-30=.32=32%=64 readers 76-64=12 A is FALSE
B. so we want to know how many people are 31-40 and prefer fiction so .38=38% and 38% of 200=76 B is FALSE
C 43 members are 21-30 so we look at the total row for the 21-30 people and see that .43 or 43% or 86 people are in the 21-30 age group C is FALSE
D. 140 members prefer fiction look at the total column for fiction and see that .70 like fiction .70=70%=140 people D is TRUE
Use b= to solve for the missing side in the triangle. You will get a rounded answer of 8.49. Then you multiply that by 2 and subtract that value from 31. Then that will be your answer.
