The table shows the number of subscribers of several internet providers. What is the mean number of subscribers for these internet providers?

We recall that in order to find the mean of a data set, we divide the sum of the values by the number of values. We add them up and divide by how many there are. In this question, we need to find the total number of subscribers and divide this by the number of companies. In order to add 1.65, 1.16, and 1.9, we need to ensure our decimal points align. We can also add a zero as a placeholder in the hundredths column.

Adding the numbers in the hundredths column gives us 11. So we carry a one to the tenths column. Six plus one plus nine is equal to 16. And adding the one that we carried gives us 17. The sum of 1.65, 1.16, and 1.9 is 4.71.

As there are three companies in total, we need to divide this value by three. Using the short division bus stop method, we see that four divided by three is equal to one remainder one. 17 divided by three is equal to five remainder two. And finally, 21 divided by three is seven. As all of our values were in millions, the mean number of subscribers is 1.57 million.
