Final answer:
The question regarding the percentage of state capitals near rivers is incomplete, as it lacks data for all state capitals. Available data show a range of percentages indicating various proximities to rivers.
Step-by-step explanation:
The question asks about the percentage of state capitals that lie within 25 miles of a river. The information provided lists various states along with percentages, most likely representing the proximity of each state's capital to a river. Calculating the overall percentage would require collecting the percentages provided and determining the average or total. However, the data provided seems incomplete and does not cover all states needed to answer the question fully. For a thorough answer, additional data representing all state capitals would be necessary. Nonetheless, the information shows that a significant number of state capitals are indeed situated near rivers. This reflects the historical importance of rivers for transportation, trade, and settlement.
For example, Mississippi's capital has the highest listed percentage at 34.0%, whereas Colorado's capital has one of the lowest at 21.0%. Such percentages suggest varying degrees of reliance on rivers across state capitals, which may be influenced by geographical and historical factors.
