Correct option is B
The given statement,
“Because x = 3 and y = 5, then x + y = 8”, is a
deductive argument based on mathematics. In deductive reasoning, the conclusion follows logically from the premises, and in this case, it relies on basic arithmetic rules. The conclusion (x + y = 8) is derived directly from the fact that x = 3 and y = 5, making it a
mathematical deduction.
Information booster:
1.
Deductive arguments are those where the conclusion is logically certain if the premises are true.
2.
Mathematics is based on deductive reasoning, where conclusions are derived using established mathematical rules and operations.
3.
Inductive arguments, in contrast, infer general principles from specific instances, and their conclusions are probable rather than certain.
Additional Knowledge:
·
Deductive reasoning provides a guarantee of the truth of the conclusion when the premises are true, often used in mathematics, logic, and formal systems.
·
Inductive reasoning, on the other hand, makes generalizations based on observations and is common in scientific investigations.
