Theories
false
If nearly all scientists agree with a theory, it may be called a scientific consensus. This consensus indicates that the theory is well-supported by extensive evidence and has undergone rigorous testing and peer review. While scientific consensus doesn't guarantee absolute truth, it reflects a strong level of agreement among experts in the field based on current knowledge.
A hypothesis does not have to be definitively provable; rather, it should be testable and falsifiable. This means that it can be subjected to experimentation or observation to determine its validity. The goal of a hypothesis is to provide a plausible explanation or prediction that can be supported or refuted through evidence. Ultimately, the scientific process relies on continual testing and refinement of hypotheses rather than absolute proof.
its absolute value is greater than or equal to 1 and less than 10
A "law" contains absolute certainty or scientific truth. A theory is very close to being a law, but without the absoluteness. That is what a theory is. If you have a pretty good idea of how something in science might work you might form a hypothesis (hye-POTH-uh-suss). With enough additional proofs and evidence, a hypothesis may someday turn into a theory.

Scientific theories.
If my memory of third grade serves me, that would be a theory. Theories are based upon observations (e.g.: Observation: That guy's left side looks limp. Theory: He had a stroke) and are not absolute, as until it is tested and proven, there is no way to tell for certain if a theory is true or not.
Science deals with building a body of knowledge through evidence-based investigations and observations. It aims to explain phenomena based on the available evidence but does not aim to offer absolute proof. This is because scientific understanding is always evolving with new evidence and perspectives.
That is correct. If the result of an experiment cannot be replicated (repeated), the theory is weakened or overturned. In addition, results in general are not absolute as it is always possible something has been overlooked that would significantly alter the theory. For example, Newton's theory of gravity was considered to be very good, and explained the motions of the planets about the sun extremely well. Except for Mercury, whose motion did not fit Newton's model. Eventually Einstein developed a superior theory of gravity (general relativity), which accounted for the motion of Mercury.
Scientific knowledge is not absolute.
All scientific theories are basically just consensuses of postulates to guide scientific research in a search for evidentiary proof. Consequently no theory is absolute fact. In the case of the Big Bang theory we also have the problem that we are trying to figure out what happened billions of years in the past, long before any human beings were around to observe those events directly. We have lots of astronomical observations which are relevant to this theory, but it is possible to imagine more than one way to interpret those observations. That said, you should also know that the evidence for the Big Bang theory is quite strong, and no one working in the field of cosmology has any serious doubt about it. It is very well supported. But it is not absolute fact. Nothing in science is taken as being absolute. For absolute truth, you must turn to religion.

The mean absolute percent prediction error (MAPE), .The summation ignores observations where yt = 0.
It is all doubtable, testable and open to disproof. This is the strength of the scientific method; it is a heuristic. It does not lead to absolute truth. There are some basic observations that are probably undeniable for all of time, but the more speculative or theoretical a scientific principle is, the more it is vulnerable to change or re-interpretation.
