Explanation for Question 33 From the Math (Calc) Section on the 2017 May Sat
Question 33 gives us a chart labeled median ages of 2 populations of selected countries in 2012, 3 and then asks, what is the range? 4 Circling that in years of the median age of the populations for the countries 5 in the table above. So they're asking for the range, 6 don't get that confused by reading the word median median is just median. 7 Age of the population is this, um, 8 this whole side. So they're asking for the range and range. 9 All you have to do is take the highest number and subtract it from 10 the lowest number. So the highest number in this list is 11 45.3 and the smallest number 12 is 17.9. 13 So now all we do with the range is we do 45.3 minus 14 17.9. And again, 15 calculator section. So we use our calculator. 16 We find out that is 27.4. 17 That's our final answer.
