There are 195 countries in the world today. This total comprises 193 countries that are member states of the United Nations and 2 countries that are non-member observer states: the Holy See and the State of Palestine

•Taiwan - the United Nations considers it represented by the People's Republic of China

•The Cook Islands and Niue, both states in free association with New Zealand which are members of several UN specialized agencies and have been recognized "full treaty-making capacity", but are neither member states nor non-member observer states.

for each of these relations on the set {1, 2, 3, 4}, decide whether it is reflexive, symmetric, antisymmetric, or transitive. {(

Rama09 [41]

Relationship R is not symmetric and is not reflexive, R is not an asymmetric relation, R is a transitive relation as represented in image.

What is a relation?

Both the relationship and the function are fairly similar to one another. After learning about function and relation, we can then study how they differ from one another. This is how we can distinguish between relation and function.
The connection can be viewed as a set of ordered pairs in discrete mathematics. The sets must not be empty in order for it to be used to connect an object through one set to the other. The relation may include two sets or more.

The relation in mathematics is the connection between different sets of values. Assume that there are different pairs of ordered pairs, x and y.

If set x and set y are related, then set x's values are referred to as its domain while set y's values are referred to as its range.

Relationship R is not symmetric and is not reflexive, R is not an asymmetric relation, R is a transitive relation as represented in image.

Find the lengths of the missing sides if side a is opposite angle a, side b is opposite angle b, and side c is the hypotenuse.

konstantin123 [22]

Hello Melissamv9321, find the lengths of the missing sides if side a is opposite angle a, side b is opposite angle b, and side c is the hypotenuse In this right triangle, you are given the measurements for the hypotenuse, c, and one leg, b. The hypotenuse is always opposite the right angle and it is always the longest side of the triangle. To find the length of leg a, substitute the known values into the Pythagorean Theorem. Solve for a2.

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 6 rows of the same length, he has 3 chairs left ov

tresset_1 [31]

If he has 9 rows of equal length there are 3 chairs left over.

If he has 7 rows of same length there are 19 left over.

It's important to note that these two setups have the same number of chairs. So we can make an equation out of it.

9x + 3 = 7x +19

2x + 3 = 19

2x = 16

x = 8

So, x (8) is the number of chairs in each row with these setups.

Plug 8 into one of the equations and you will find how many chairs total there are.

9(8) + 3 = 75

There are 75 chairs total
