An international health organization collected global data regarding a certain disease for each of 14 consecutive years (Y1 – Y14). The graph shows the annual numbers of cases, countries, countries with local cases (i.e., cases for which the infection was contracted within the country), and countries with non-local cases (i.e., cases for which the infection was contracted outside of the country).
From each drop-down menu, select the option that creates the most accurate statement according to the information provided.
The percent increase in the number of cases of the disease from Y9 to Y12 was, to the nearest 10%, .
The average (arithmetic mean) of the numbers of countries with local cases from Y1 to Y5 was, to the nearest 5 countries, .

Part 1:
The percent increase in the number of cases of the disease from Y9 to Y12 was, to the nearest 10%, _________.
Solution:
For Y9, the number of cases if 200,000 and for Y12 the number of cases is 600,000. To calculate the percent increase in the number of cases:
Increase = 600,000 - 200,000 = 400,000.
% Increase = ( 400,000 / 200,000 ) * 100 = ( 4 / 2 ) * 100 = 200 %
Part 2:
The average (arithmetic mean) of the numbers of countries with local cases from Y1 to Y5 was, to the nearest 5 countries, _________.
Solution:
Y1 - 51 countries
Y2 - 50 countries
Y3 - 39 countries
Y4 - 40 countries
Y5 - 55 countries
Mean = ( 51 + 50 + 39 + 40 + 55 ) / 5 = 235 / 5 = 47.
Closest option choice nearest to 5 is 45.

Part 2: 45 countries
The percent increase in the number of cases of the disease from Y9 to Y12 was, to the nearest 10%, _________.
Solution:
For Y9, the number of cases if 200,000 and for Y12 the number of cases is 600,000. To calculate the percent increase in the number of cases:
Increase = 600,000 - 200,000 = 400,000.
% Increase = ( 400,000 / 200,000 ) * 100 = ( 4 / 2 ) * 100 = 200 %
Part 2:
The average (arithmetic mean) of the numbers of countries with local cases from Y1 to Y5 was, to the nearest 5 countries, _________.
Solution:
Y1 - 51 countries
Y2 - 50 countries
Y3 - 39 countries
Y4 - 40 countries
Y5 - 55 countries
Mean = ( 51 + 50 + 39 + 40 + 55 ) / 5 = 235 / 5 = 47.
Closest option choice nearest to 5 is 45.
Part 1: 200 %
Part 2: 45 countries
