There are too many variables associated with this question to answer it properly: #1) The square footage of the area to be covered determines the amount of paint necessary. #2) Cheap paint gives cheap results. #3) The cost of paying the painter. #4) The cost of keeping the boat out of water long enough to paint it.
Depends on how much it cost them to make it in the first place, how famous they are and how many were sold. There are too many variables to answer this question.
Cannot be given a specific answer - too many variables. What type battery components? Frequency of usage? Length of charge time(s)? How long on the charger? Number of cycles?
Ryan Russell photographed all of the album art. He is a good friend of the band and has also taken many photos of the band.
The worth of a celebrity photograph has many variables. Is it mass-produced (how many are in existence)? How famous is the photographer? What is the condition of the piece? Is it signed by the artist? If it's a band, did all members sign it? If it is signed, have the signature/s been authenticated?
In a properly designed experiment, it is important to have at least 2 controlled variables. With two variables you are able to remove one at a time and see the effect in your setup.
In a correctly designed experiment, there should typically be one independent variable to ensure that the effect on the dependent variable can be clearly attributed to that specific factor. However, in some cases, multiple independent variables can be included as long as the experiment is designed to control for their interactions and potential confounding effects. It's essential to balance complexity with clarity, ensuring the experiment remains manageable and the results interpretable.
An experiment of any kind can have infinitely many variables. A controlled experiment can have just as many, provided that all but one are kept exactly the same.
All variables except one, the experimental variable, are kept constant in an experiment.

As few as possible.

There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
A experiment should only have one variable.
Most science experiments will have two independent variables. Fundamentally, an experiment will want as few variables as possible for better results.
There are complex models that allow researchers to study several variables if the experiment is carefully designed and very carefully carried out. These models can show whether a variety of variable interactions occur, and if that is your focus then these models are good. But the best experiments investigate a small number of variables, as few as one.
