Which is a value that should remain constant for all samples in this experiment?
It could be many things such as temperature or pressure.
Would you hear a change in pitch if you are on a moving train and the train whistle blows?
Since you are also on the moving train, the pitch should remain constant.
How many variables should you have when you test a hypothesis?
there should be atleast 1
How many variables should there be in a good experiment?
There should be one dependent variables. Depending on the type of research you are doing, the amount of independent variables will change. If you are doing research on a large scale, you will use more independent variables. If it's on a small scale, you will use very little. If you are not able to run your regression it means your sample size is too small or you have too many independent variables.
How many experimental variables should you have?
There's no "Limit", but the less you have, the better the experiment.
What is a manipulted variable?
When all other variables should be kept unchanged.
What is the difference between independent variable and constant?
3x-4y+4x+2 the constant is the number without a variable(+2) the variable(s) will be x and y.independent varibles will be variables standing alone,with no numbers next to it.EG 2+x.the independent variable is x
What is the difference between static and dynamic variables?
Static variables (should) remain the same e.g. temperature of a water bath, k constant of a particular spring. Dynamic variables change as the experiment progresses e.g. air temperature and pressure, amount of natural light.
What are all the variables?
There are 'constant variables' , 'independant variables' and 'dependent variables' Constant Variable- things in the experimment that should be kept the same Independant variables- something that can be varied in an experiment Dependant variable- something that can be affected
What is constant variable in c?
Constant variables refers to those variables whose values cannot be changed. These variables should be initialized along with their declaration. Attempt to change the value of a constant variable will generate compile error. The syntax for declaring a constant variable is:const data-type variableName = value;
The total amount of energy in the univeres changes?
No, it should remain constant.
How many independent variables should an investigation have?
There can only be one independent and one dependent variable. All other variables should be classed as control variables and must be kept constant to achieve a fair test.
How do you take care of a child born in the year of the dragon?
Care for a child should remain unchanged regardless of which zodiac year it was born in.
How do you use constants in php?
Constants are simple pieces of data which cannot be changed during PHP script execution. It is useful for storing data which should remain unchanged, like a maximum or minimum value of a variable, etc.Before first use, constant should be defined: ...define("MY_MAX_VALUE", 505);... After this, you can use it:...if ($my_variable < MY_MAX_VALUE){... (some code here)}...
Which is a value that should remain constant for all samples in this experiment?
It could be many things such as temperature or pressure.
How often should you put oil in your van?
Level should remain fairly constant. oil changes 3-5k mi. If you are losing oil, that is a sign of wear.
Does a ratio remain unchanged if 1 is added to both the numerator and denominator?
You should not do that...1/4 and 2/5 are not the same thing(1 divided by 4 = 0.25) (2 divided by 5 = 0.4)
