Final Answer:
The combined customer count of the northeast and southeast for the first and second time periods is [Sum of customers in the northeast for time periods 1 and 2] + [Sum of customers in the southeast for time periods 1 and 2].
Step-by-step explanation:
To find the combined customer count for the northeast and southeast regions across the first and second time periods, we'll need to sum up the customer counts separately for these regions and then add them together.
Let's denote the customer count for each region and time period:
- Northeast for Time Period 1: X1
- Northeast for Time Period 2: X2
- Southeast for Time Period 1: Y1
- Southeast for Time Period 2: Y2
The combined customer count for the northeast across the two time periods is X1 + X2.
Similarly, the combined customer count for the southeast across the two time periods is Y1 + Y2.
Therefore, to find the total combined customer count for the northeast and southeast regions for the first and second time periods, we need to add the sums of both regions' customer counts:
Combined count = (X1 + X2) + (Y1 + Y2).
By calculating the individual sums for each region across both time periods and then adding them together, we'll arrive at the final combined customer count for the northeast and southeast regions across the specified time periods.
