Questions & Step-by-Step Solutions
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.
