Final answer:
To determine the ratio of Fire emergency Calls to medical emergency calls for 2012, one would need the frequency of each call type from data for that year, then divide the number of fire emergency calls by the number of medical emergency calls and simplify if possible.
Step-by-step explanation:
The question requires an analysis of a dataset to determine the ratio of Fire emergency Calls to medical emergency calls in the year 2012. To provide an answer, data from the specified year would need to be referenced, which typically involves counting the respective incidences of each type of call and then forming a ratio of these two quantities. An example would look like this: If there were 120 fire emergency calls and 300 medical emergency calls in 2012, the ratio would be 120 to 300, or simplified to 2 to 5. The question is rooted in mathematical concepts of ratios and proportions, often encountered in high school curricula.
