Final answer:
The relationship between CO₂ emission and car information is most accurately represented by multiplication, as emissions are typically proportional to the amount consumed or used.
Step-by-step explanation:
The relationship between CO₂ emission and car information can be described mathematically in various ways, such as through multiplication, division, addition, or subtraction. Given the context provided, where the computation involves the annual rate and cumulative emission of CO₂, and factors such as carbon-intensity of coal and how much CO₂ is absorbed by the ocean and land, the most likely mathematical operation to be used would be multiplication. This is because emission levels are often proportional to the amount of fuel burned, and thus, we typically use multiplication to model the relationship between variables such as 'car information' and CO₂ emissions.
The relationship between CO₂ emission and car information is described as a multiplication.
The relationship between CO₂ emission and car information can be described as a multiplication. The equation would be CO₂ emission = car information × (some coefficient). This means that the CO₂ emission is directly proportional to the car information, and the coefficient represents the specific relationship between the two variables.
If we refer to Figure 9.3 and the additional information provided, we can deduce that the equation would most likely involve multiplication since emissions are commonly determined by multiplying the amount of fuel consumed by a factor representing the emissions per unit of fuel.
