Question

use the graph to answer the questions. 1. what kind of graph is shown? circle it. line graph circle graph 2. which is the largest age group? 3. which is the smallest age group? 4. which two groups make up about half of the united states’ population? 5. estimate how many more people are in the under 18 age group than the over 64 age group. show your estimate. 6. estimate the total number of people over the age of 44 in the united states. show your estimate. 7. estimate the total population of the united states. show your estimate. u.s. population (by age group) 18 - 24 26,737,766 over 64 31,241,832 45 - 64 46,371,009 25 - 44 80,754,835 under 18 63,604,432

Explanation:

Step1: Identify graph type

Circle graph (pie chart) shown.

Step2: Find largest age group

25-44 has 80,754,835 (largest number).

Step3: Find smallest age group

18-24 has 26,737,755 (smallest number).

Step4: Two groups for ~half population

Sum 25-44 (80,754,835) + 45-64 (46,371,009) ≈ 127M; total ≈249M, ~half.

Step5: Under 18 - over 64

63,604,432 - 31,241,832 = 32,362,600.

Step6: Over 44 population

45-64 (46,371,009) + over 64 (31,241,832) = 77,612,841.

Step7: Total U.S. population

Sum all groups: 26,737,755+31,241,832+46,371,009+80,754,835+63,604,432=248,709,860.
