1
Step-by-step explanation:
hope this helps
Let's check.
x = 5π/24
4x = 5π/6
cos 4x = cos(5π/6) = cos 150° = -√3/2
cos² 4x = (-√3/2)^2 = 3/4
4 cos² 4x -3 = 4 (3/4) - 3 = 0
Answer: TRUE
No of outcomes =16
favourable outcome=4

Answer:
It is so easy u should get this right.
First draw a circle and there is an arc that is like forming a triangle inside a circle and then ab angle is 100 degree and outside is the center of the circle. And since u try to find how much is outside it most likely means that 100-60=40
so it b 40.

Answer:
- <em>Yes, an answer can be incorrect even it it looks reasonable.</em>
Explanation:
Yes, an answer can be incorrect even if it looks reasonable, for two main reasons:
- The assumptions (premises or statements) on which the reasoning is based are wrong.
- The reasoning sounds good but it is a fallacy.
To avoid the first condition you must be sure about the facts, which may be information from an experiment that you performed or from a source. In order for an answer be correct, make sure your premises are true.
Dealing with the second condition, a fallacy is an argument that seems strictly logical but is misleading: you must learn which reasonings are really valid; this is, that the conclusion unequivocally follows from the premises.
There are rules for the arguments to be valid, and that is the object of logic study.
Fallacies are sometimes used by those interested in supporting a point of view without having true reason on their side. You should have some knowledges about logic to avoid being victim of the fallacies, which can drive you to make wrong decisions.
