Final answer:
The question reflects high school-level Mathematics focusing on geometry, specifically vector displacement, graphical methods for resultant displacement, and creating bar graphs for statistical data.
Step-by-step explanation:
The question relates to the subject of Mathematics, specifically within the field of geometry and vectors, as it mentions displacement in a city involving a graphical representation. It also touches upon graphical methods to find resultant displacement and geographic direction for a pedestrian and requires constructing a bar graph related to voter populations, which involves statistical representation.
Moreover, the question includes considerations for distance measurement based on given scenarios and proportions. The occurrence of similar keywords across the multiple parts of the question indicates that these are mathematical tasks typically encountered by students at the high school level.
Incomplete question is:. There are 6 districts in a city. Each district is an alternative location for new facilities. Each district has a demand of \( 1,2,5,3,3,4 \), respectively. Distances between these districts are g
