Answer:
Archimedes showed that the point where the medians are concurrent (the centroid) is the center of gravity of a triangular shape of uniform thickness and density
Step-by-step explanation:
Answer: True.
The ancient Greeks could bisect an angle using only a compass and straightedge.
Step-by-step explanation:
The ancient Greek mathematician <em>Euclid</em> who is known as inventor of geometry.
The Greeks could not do arithmetic. They had only whole numbers. They do not have zero and negative numbers.
Thus, Euclid and the another Greeks had the problem of finding the position of an angle bisector.
This lead to the constructions using compass and straightedge. Therefore, the straightedge has no markings. It is definitely not a graduated-rule.
As a substitute for using arithmetic, Euclid and the Greeks learnt to solve the problems graphically by drawing shapes .
The equation of a line is y = mx + b
We know there is a b because the y intercept is not zero, so the first choice is wrong. We also know the last choice is wrong because this problem definitely has a slope (m).
The slope of the line of best fit seems to be closest to 3.25, meaning it goes up about that much for every one unit it goes to the right.
The second choice is correct.
