Question

which is the first step for analyzing mathematical models? (1 point)
determine the data needed
analyze the data.
define the problem and identify parameters
draw reasonable conclusions

Explanation:

When analyzing mathematical models, the first step is to define the problem and identify parameters. Without clearly defining the problem and knowing the relevant parameters, it's impossible to determine the data needed, analyze the data, or draw conclusions. Determining data needed, analyzing data, and drawing conclusions are subsequent steps that rely on having a defined problem and identified parameters.

Answer:

Define the problem and identify parameters
