Final answer:
The statement is false as a numerical coefficient refers to the numeric factor in a term, not the degree, which is indicated by the exponent of the variable.
Step-by-step explanation:
The statement "A numerical coefficient is a term with a degree of three" is False. A numerical coefficient in mathematics refers to the numerical factor in a term of an algebraic expression or polynomial. For instance, in the term 7x^3, the number 7 is the coefficient, and the term has a degree of three, which is determined by the exponent of the variable x. However, the coefficient itself does not determine the degree of the term; it is simply a factor of the term.
In the context of significant figures, a numerical coefficient might also be assumed to need careful consideration regarding the number of digits that express the precision of a measurement. This concept is important in scientific measurements and calculations.
