If the mean of a set of numbers is 25 and there are 12 numbers in the set, what is the total sum of the numbers?

If the mean of a set of numbers is 25 and there are 12 numbers in the set, what is the total sum of the numbers?

Step 1: Understand that the mean (average) of a set of numbers is calculated by adding all the numbers together and then dividing by the number of items in the set.
Step 2: In this case, the mean is given as 25.
Step 3: We also know that there are 12 numbers in the set.
Step 4: To find the total sum of the numbers, we can use the formula: Total sum = Mean * Number of items.
Step 5: Substitute the values into the formula: Total sum = 25 * 12.
Step 6: Calculate the total sum: 25 * 12 = 300.

Mean Calculation – Understanding that the mean is the total sum of a set of numbers divided by the count of numbers.
Multiplication of Mean and Count – Applying the formula for total sum by multiplying the mean by the number of items in the set.
