3. For the data shown above, what percentage (to the nearest whole number) of people ate pies for lunch :

Explanation

The given data shows that 8 people ate pies for lunch out of the total number of people surveyed. To find the percentage, we divide the number of people who ate pies (8) by the total number of people surveyed (8) and multiply by 100. This gives us a percentage of 100%. Therefore, the correct answer is 8, 8%.

6. The image above is a :

Explanation

The image above is a percent frequency bar chart because it represents the distribution of a variable as a percentage of the total. Each bar in the chart represents a category, and the height of the bar represents the percentage of data points that fall into that category. This type of chart is useful for comparing the relative frequencies of different categories and understanding the overall distribution of the data.

Submit
7. The image above is a :

Explanation

The image above is a frequency bar chart because it displays the frequency or count of different categories or values on the y-axis, while the x-axis represents the categories or values themselves. Each bar represents a category or value, and its height corresponds to the frequency or count. This type of chart is commonly used to show the distribution or frequency of data in different categories.

11. The bar chart above shows the lunch choices for a group of people. The pies and sandwiches come from the bakery, while the sausages, burgers and fish & chips come from the local takeaway store.What percentage (to the nearest whole number) of people bought their lunch from the takeaway store?

Explanation

The bar chart shows the lunch choices for a group of people. The pies and sandwiches come from the bakery, while the sausages, burgers, and fish & chips come from the local takeaway store. To find the percentage of people who bought their lunch from the takeaway store, we need to calculate the proportion of the takeaway store choices out of the total choices. In this case, the takeaway store choices are sausages, burgers, and fish & chips, which have a total count of 62. The total choices for lunch, including both bakery and takeaway store options, are not given. Therefore, it is not possible to determine the exact percentage.

Submit
12. The image above is a :

Explanation

The image above is a percent frequency bar chart because it displays the frequency of different categories as a percentage of the total. Each bar represents a category, and the height of the bar represents the percentage of occurrences of that category. This type of chart is useful for comparing the relative frequencies of different categories and identifying any patterns or trends.

17. For the data shown above, what percentage (to the nearest whole number) of people wore large shirts :

Explanation

The given data shows that 26 people wore large shirts out of the total number of people surveyed.

Therefore, the correct answer is 26, 26%.
