For this specific problem, the statement “every chord is a diameter” is
false. The correct answer between all the choices given is the third
choice or letter C. I am hoping that this answer has satisfied your query and
it will be able to help you in your endeavor, and if you would like, feel free
to ask another question.
Answer:
a) 10
b) 15
c) 190
d)
Step-by-step explanation:
Lets start with the generic item (d). In order to draw a chord we need to pick two endpoints from the total of n points of the circle and draw the line between them. The total amount of lines we can draw is equivalent to the total pair of points we can pick to draw them.
In other words, we can draw as many chords as the amount of subsets of 2 elements we can pick from a set of n. That number is the combinatorial number of n with 2 given by
a) If n = 5, the answer is
there are 10 possibilities
b) for n = 6
15 possibilities
c) for n = 20, we have
possibilities.
I hope that works for you!
Luis is wrong because 8 to the third power is not 24, but is 512. He multiplied 8 by 3 instead of doing 8x8x8, so Luis made an incorrect claim.
