Answer 1

To calculate the arithmetic mean, sum up all numbers and divide by the total count.

Step-by-step explanation:

The arithmetic mean, also known as the average, is calculated by summing up all the numbers and dividing the sum by the total number of numbers. To calculate the arithmetic mean of the given numbers:

1. Calculate the sum of all the numbers.
2. Count the total number of numbers.
3. Divide the sum by the total number of numbers to get the average.

For example, to calculate the arithmetic mean of 7 and 17, the sum would be 7 + 17 = 24. Since there are two numbers, the average is 24 ÷ 2 = 12. Similarly, you can calculate the mean for the other sets of numbers given.
