Answer 1

To find the percentage of kids who prefer veggies, we can use the information provided in the table.

You mentioned that there are 70 kids who prefer veggies out of a total of 250 kids surveyed.

To find the percentage of kids who prefer veggies, we use the formula:

\[
\text{Percentage} = \left( \frac{\text{Number of kids who prefer veggies}}{\text{Total number of kids}} \right) \times 100
\]

Substituting in the numbers:

\[
\text{Percentage} = \left( \frac{70}{250} \right) \times 100
\]

Calculating this gives:

\[
\text{Percentage} = 0.28 \times 100 = 28\%
\]

So, 28% of kids surveyed prefer veggies.

Now, we can also find the percentage of kids who prefer meat:

\[
\text{Percentage of kids who prefer meat} = \left( \frac{180}{250} \right) \times 100 = 72\%
\]

So the completed relative frequency table for kids would look like this:

\[
\begin{array}{|c|c|c|}
\hline
\text{Prefer Meat} & \text{Prefer Veggies} & \text{Total} \\
\hline
72\% & 28\% & 100\% \\
\hline
\end{array}
\]

For adults, since there are 48 adults who prefer veggies out of a total of 80 adults surveyed:

\[
\text{Percentage of adults who prefer veggies} = \left( \frac{48}{80} \right) \times 100 = 60\%
\]

Thus, the completed relative frequency table for adults becomes:

\[
\begin{array}{|c|c|c|}
\hline
\text{Prefer Meat} & \text{Prefer Veggies} & \text{Total} \\
\hline
40\% & 60\% & 100\% \\
\hline
\end{array}
\]

In summary:
- **Kids:** 28% prefer veggies.
- **Adults:** 60% prefer veggies.
