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!
Answer:
14
Step-by-step explanation:
it's how far away the number is from zero.
I got a better answer then 24... 25
In the afternoon Rosa read 13 fewer pages as compared to the number of pages read in the morning
So we subtract 13 from 57 to get the number of pages read in the afternoon.
That is the number of pages read is the afternoon
Therefore Rosa read 44 papers in the afternoon
