What are some important factors when deciding an appropriate scale for a model?

The main problem with scaling down real world constructions is that small components do not react to forces in the same way as it's full size target. A very small internal combustion engine will not scale completely. Gas flows, liquid channels and piston rods will not operate properly due to capillary action and viscosity of liquids retarded by tube wall friction and slowing of gases in small diameter tubes. Piston rods break because they are not strong enough. Spring actions of suspension system modelling also don't scale. In bridge and aircraft designs in a wind tunnel, scaling to very small proportions will not show aerodynamic flaws in prototype designs. Earthquake proofing building models on shaking tables do not have the same resonant frequency of the full size building. These factors don't scale.

When could you use theoretical probability?
When there is a good theoretical model for the experiment and the model allows you to identify all the factors affecting the outcome and determine their impact on the outcome. Even if you cannot identify all the factors, you can still use theoretical probability but the predictions from your model will be less reliable. Econometrics is a good example of using theoretical probability based on an incomplete understanding of the model.
What is the impact of multicollinearity on a linear model?
It doesn't have much impact on the reliability of the model, but adds to the noise with unnecessary overfitting. Multicollinearity impacts on your assessment of which factors are really influential. Factors that are redundant should be dropped in good model design. For example, you could come up with a fairly good linear model predicting fuel economy that includes engine capacity and engine weight. But since capacity and weight are correlated one is redundant and should be dropped.
The variability of a solution to changes in the model and input data is an important part of the analysis of the results?
sensitivity analysis
Role of mathematics in Business decisions?
The role of mathematics in Business decisions has very important in the process of mangerial decision models and alorithms. To turn to the specific aspects of te quantitative decision making process, it is possible to recognize three distinct phases in every decision situation. First is carefully defined the problem, second is a conceptual model to be generated and third is the selection of the appropriate quantitative model thay may lead to a solution. lastly a specific alogorithm is selected . An alorithms are the ordely delineated sequnces of mathematical operations that lead to a solution. The alorithms generate the decision which is subsequently implemented managerial action program. The entire process is shown below: Defined problem------>Conceptual model--->Quntitative Model---->Algorithms---->decision----Action programs LE

What is my used car's value?
There are a lot of factors in deciding the value of a used car. What model is your car? What make? What is the millage? And what is the condition of the car? If you take the car to a dealer's lot, they would be able to give you a ballpark estimate of the car's worth.

Is it a good idea to start with a simple business?
Some businesses are successful with a simple model, while others find that a more complex model is necessary for growth. It depends on a variety of factors, including the industry, the target market, and the business goals. Starting with a simple business model can be a good way to test the waters and see if there is a market for your product or service. It can also be less risky and less expensive to start up. However, a simple business model may not be enough to sustain long-term growth or to reach a larger market. Ultimately, it is important to carefully consider all factors before deciding whether a simple or complex business model is right for your company.
