Final answer:
Without the actual scatter plot, it's not possible to determine the number of offices with 6 computers. The information could be obtained by counting the relevant points on the x-axis of the provided scatter plot.
Step-by-step explanation:
To determine how many offices had 6 computers using the given scatter plot, you would visually inspect the plot and count the number of points that correspond to the value of 6 on the x-axis (assuming computers are represented on the x-axis). The count of these points gives the number of offices with that specific number of computers. Since I do not have the actual scatter plot, I cannot provide the exact answer to how many offices had 6 computers.
