In a data set, if the mean is 50 and the sum of all values is 500, how many values are there?

In a data set, if the mean is 50 and the sum of all values is 500, how many values are there?

Step 1: Understand that the mean is the average of all values in a data set.
Step 2: Know that the mean is calculated by dividing the sum of all values by the number of values.
Step 3: Use the formula: Mean = Sum / Number of values.
Step 4: Rearrange the formula to find the number of values: Number of values = Sum / Mean.
Step 5: Substitute the given values into the formula: Number of values = 500 / 50.
Step 6: Calculate the result: 500 divided by 50 equals 10.
