Answer

Explanation:

Step1: Count total number of dots

Count all the dots on the dot - plot. There are 1 + 2+1 + 1+3 + 7+4 = 19 dots.

Step2: Count number of dots for ages over 40

Count the dots for ages 41 - 50. There are 3 + 7+4 = 14 dots.

Step3: Calculate the percentage

Use the formula $\text{Percentage}=\frac{\text{Number of people over 40}}{\text{Total number of people}}\times100%$. So, $\text{Percentage}=\frac{14}{19}\times100%\approx73.7%$.

Answer:

73.7
