If the mean of a dataset is 50 and there are 10 numbers, what is the total sum of the numbers? (2021)

Step 1: Understand that the mean (average) is calculated by adding all the numbers together and then dividing by the number of numbers.
Step 2: In this case, the mean is given as 50.
Step 3: We also know that there are 10 numbers in the dataset.
Step 4: To find the total sum of the numbers, we can use the formula: Total sum = Mean * Number of elements.
Step 5: Substitute the values into the formula: Total sum = 50 * 10.
Step 6: Calculate the total sum: 50 * 10 = 500.

Mean Calculation – Understanding that the mean is the total sum of the numbers divided by the number of elements.
Basic Arithmetic – Applying multiplication to find the total sum from the mean and the count of numbers.
