The data in the table on the left shows how the ages of the
US population were distributed in 1995. Suppose
is the fraction of the US population of age less than
years old. Find the values of .
|
Age group (in years) | Fraction of total population |
0-10 | 15% = 0.15 |
10-20 | 14% = 0.14 |
20-30 | 14% = 0.14 |
30-40 | 17% = 0.17 |
40-50 | 14% = 0.14 |
50-60 | 10% = 0.10 |
60-70 | 8% = 0.08 |
70-80 | 5% = 0.05 |
80-90 | 2% = 0.02 |
90-100 | 1% = 0.01 |
