The best models a. are mathematical models. b. replicate all aspects of the real-world object or decision. c. replicate the characteristics of a component in isolation from the rest of the system.

accurately reflect relevant characteristics of the real-world object or decision

Step-by-step explanation:

a. are mathematical models. b. replicate all aspects of the real-world object or decision. c. replicate the characteristics of a component in isolation from the rest of the system.

accurately reflect relevant characteristics of the real-world object or decision

A model is an abstraction of reality. not all good models are mathematical. there are good models in economics that are accurate and do not use maths. e.g. law of demand

It is impossible for a model to replicate all aspects of the real-world object or decision. It will only be able to reflect relevant characteristics of the real-world object or decision. All other factors would be held constant

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
