Question

The ratio of the number of people living in Adley to the number of people living in Bridford is given by the ratio of the areas of the pie charts. What proportion of the total number of people living in these two towns live in Adley and are aged 0-19? Give your answer to 3 significant figures. (The method on how to answer would be appreciated).

Answer 1

The question asks for the proportion of the total number of people living in Adley and Bridford who are specifically in Adley and aged 0-19. The ratio provided must be applied to pie chart data which we don't have, thus we cannot compute the exact proportion without additional information. Typically, a pie graph is used to represent such data, showing age distributions in each population.

Step-by-step explanation:

To find out the proportion of the total number of people living in Adley and Bridford who live in Adley and are aged 0-19, we use the given ratio from the areas of the pie charts. The ratio for the population distribution between Adley and Bridford is roughly calculated as (35% / 6%) / (65% / 94%) which is approximately 8.4. This means that, for every person aged 0-19 in Bridford, there are about 8.4 in Adley. However, this provides a ratio rather than a percentage and further information concerning the absolute numbers or percentages shown on the pie charts for each age group and town would be needed to calculate the precise proportion of the total population.

A pie graph represents each slice as a share of the total, while a bar graph compares quantities using the height of bars. In this case, the pie graph for Adley and Bridford would show the proportions of different age groups, including those aged 0-19.

Answer 2

Since the degree measure of the segment 0-19 in Adley is 70*, and the degree measure of the segment 0-19 in Bridford is 60*...........

The proportion is simply 70/60 or 7/6 in simple terms.
