Oct 13, 2025 by wbrum.org 29 views

Introduction

In this problem, we are given a table showing the number of apples in 11 out of 12 bags on a market stall. The mean number of apples in each bag is 8. We need to calculate the number of apples in the 12th bag. To do this, we will use the concept of mean and the total number of apples in the 11 bags.

Calculating the Total Number of Apples in 11 Bags

Bag Number	Number of Apples
1	7
2	9
3	8
4	10
5	6
6	11
7	8
8	9
9	7
10	10
11	12

To find the total number of apples in the 11 bags, we need to add up the number of apples in each bag.

# Define the list of apples in each bag
apples_in_each_bag = [7, 9, 8, 10, 6, 11, 8, 9, 7, 10, 12]
total_apples = sum(apples_in_each_bag)
print("Total number of apples in 11 bags:", total_apples)

Calculating the Total Number of Apples in 12 Bags

Since the mean number of apples in each bag is 8, the total number of apples in 12 bags can be calculated by multiplying the mean by the total number of bags.

# Define the mean number of apples in each bag mean_apples_per_bag = 8 total_bags = 12 total_apples_12_bags = mean_apples_per_bag * total_bags

print("Total number of apples in 12 bags:", total_apples_12_bags)

Calculating the Number of Apples in the 12th Bag

Now that we have the total number of apples in 11 bags and the total number of apples in 12 bags, we can calculate the number of apples in the 12th bag by subtracting the total number of apples in 11 bags from the total number of apples in 12 bags.

# Calculate the number of apples in the 12th bag apples_in_12th_bag = total_apples_12_bags - total_apples

print("Number of apples in the 12th bag:", apples_in_12th_bag)

Conclusion

In this problem, we used the concept of mean and the total number of apples in 11 bags to calculate the number of apples in the 12th bag. We first calculated the total number of apples in 11 bags by adding up the number of apples in each bag. Then, we calculated the total number of apples in 12 bags by multiplying the mean number of apples in each bag by the total number of bags. Finally, we calculated the number of apples in the 12th bag by subtracting the total number of apples in 11 bags from the total number of apples in 12 bags.

Discussion

This problem is a classic example of how to use the concept of mean to solve a real-world problem. The mean number of apples in each bag is a useful piece of information that can be used to make predictions about the total number of apples in a set of bags. In this case, we used the mean to calculate the total number of apples in 12 bags, and then used that information to calculate the number of apples in the 12th bag.

Example Use Cases

This problem can be used to teach students about the concept of mean and how to use it to solve real-world problems. It can also be used to demonstrate how to use mathematical concepts to make predictions about the world around us.

Step-by-Step Solution

Calculate the total number of apples in 11 bags by adding up the number of apples in each bag.
Calculate the total number of apples in 12 bags by multiplying the mean number of apples in each bag by the total number of bags.
Calculate the number of apples in the 12th bag by subtracting the total number of apples in 11 bags from the total number of apples in 12 bags.

Code Solution

# Define the list of apples in each bag
apples_in_each_bag = [7, 9, 8, 10, 6, 11, 8, 9, 7, 10, 12]
total_apples = sum(apples_in_each_bag)
mean_apples_per_bag = 8
total_bags = 12
total_apples_12_bags = mean_apples_per_bag * total_bags
apples_in_12th_bag = total_apples_12_bags - total_apples
print("Number of apples in the 12th bag:", apples_in_12th_bag)

Mathematical Formulation

Let A be the number of apples in the 12th bag. Then, the total number of apples in 12 bags is 8 * 12 = 96. The total number of apples in 11 bags is 7 + 9 + 8 + 10 + 6 + 11 + 8 + 9 + 7 + 10 + 12 = 97. Therefore, A = 96 - 97 = 1.

Final Answer

The final answer is 1.

Introduction

In our previous article, we calculated the number of apples in the 12th bag on a market stall. The mean number of apples in each bag is 8, and the table shows the number of apples in 11 of the bags. We used the concept of mean and the total number of apples in 11 bags to calculate the number of apples in the 12th bag.
