Answer:
sampling error is not known
Step-by-step explanation:
Probability sampling may be defined as the sampling technique where the researcher or the experimenter chooses the samples from the larger population group using such method that is based on probability theory.
While non probability sampling is the kind of sampling method which is not feasible or possible for random sampling. It is the opposite of the probability sampling method. Here, the odds of any individual to be selected for any sample cannot be calculated.
The difference between the two is that the sampling error is not known.
2x^2-x+x^2-3x combine like terms
3x^2-4x set equal to zero and factor
x(3x-4)=0 solve each individual factor to find the solutions/roots
x=4/3, 0
