Question

complete the following sentence. in 2020, the median age at first marriage of women in a certain country (26.9 years) was ____ percent less than the median age at first marriage of men in that country (32.2 years). in 2020, the median age at first marriage of women in a certain country (26.9 years) was □ percent less than the median age at first marriage of men in that country (32.2 years). (round to one decimal place as needed.)

Explanation:

Step1: Find the difference in ages

First, we calculate the difference between the median age of men and women. The formula for the difference is \( \text{Difference} = \text{Men's Age} - \text{Women's Age} \).
Substituting the given values: \( 32.2 - 26.9 = 5.3 \)

Step2: Calculate the percentage decrease

The formula for percentage decrease is \( \text{Percentage Decrease} = \frac{\text{Difference}}{\text{Men's Age}} \times 100 \).
Substituting the values we have: \( \frac{5.3}{32.2} \times 100 \)
First, calculate \( \frac{5.3}{32.2} \approx 0.1646 \)
Then multiply by 100: \( 0.1646 \times 100 = 16.46\% \)
Rounding to one decimal place, we get \( 16.5\% \)

Answer:

16.5
