We don't know what kind of sets.
A rectangle or a square are sets of quadrilaterals with two pairs of right angles. They each have two pairs of right angles and two sets of equal sides.
This assumes you mean a regular octagon. There are 4 pairs where the diagonals each skip two vertices. Then there are 4 sets of three parallel diagonals where one is the main diagonal (skips three vertices) and two skip just one vertex. For each of these sets of three, you can choose three pairs of two. That makes 12 pairs all up. So there are 4 + 12 = 16 pairs.
Pairs Of Chromosomes Are Called :Sets
Its has 2 sets of lone pairs
There are 5 sets of 3 parallel diagonals (where one is a major diagonal and 2 of them span 2 vertices. Each set makes 3 pairs, so there are 5 * 3 = 15 pairs. There are 5 sets of 4 parallel diagonals (where 2 of them span 1 vertex, and 2 of them span 3 vertices. Each set makes 6 pairs, so there are 5 * 6 = 30 pairs. So that's 15 + 30 = 45 pairs.
A relation has pairs of numbers. A function is a special relation where for each input there is one and only one output.
Depends on what sets means. If it is pairs of letters then it is bookkeeper
A decagon need not have any. It can have five pairs, or two sets of 5 each, or various combinations in between.
Double bond with two sets of lone pairs on each O. .. .. O=O .. ..
In iambic pentameter, each line contains five pairs of syllables, with the stress falling on every other syllable. This results in a total of ten syllables per line.
14 ve- so 7 bonds/lone pairs. Cl will have three sets of lone pairs on it and F will have three sets of lone pairs on it. There is a single bond between Cl and F 1 bond, 6 lone pairs = total number of ve-
It is when two sets of ranges do not overlap
