Question

A pie chart shows the following distribution: 1 to 2, 35; 3 to 4, 18; 5 to 6, 13; 7 plus, 11. Each segment of the pie chart shows a different pattern.

Heraldo surveyed a group of people and asked them how many tattoos they had. His results are represented in the circle graph. What percentage of people responded with 1–2? Express the answer as a decimal, and round to the nearest tenth.

Answer 1

To find the percentage of people who responded with 1–2 tattoos, we first need to calculate the total number of people surveyed. We can do this by summing the number of respondents in each category:

• 1 to 2 tattoos: 35
• 3 to 4 tattoos: 18
• 5 to 6 tattoos: 13
• 7 plus tattoos: 11

Total number of people = 35 + 18 + 13 + 11 = 77

Next, we calculate the percentage of people who responded with 1–2 tattoos:

\[ \text{Percentage} = \left(\frac{\text{Number of people with 1-2 tattoos}}{\text{Total number of people}}\right) \times 100 \]

Substituting in the values we obtained:

\[ \text{Percentage} = \left(\frac{35}{77}\right) \times 100 \approx 45.4545... \]

Now we round this to the nearest tenth:

The percentage of people who responded with 1–2 tattoos is approximately 45.5%.
