(19459006) The Definition of the Combined Two Set ] - There is enough material related to the set taught in junior high school. One of them is about a combination of two sets. Do you know what is meant as a combination of two sets? It is better if you read again the material The Basic Mathematical Formula which discusses Understanding, Theory, Concepts And Types of Mathematical Set if you already understand Well what it is called the set then you certainly will be easier in understanding the material to be discussed in this article. Before we go further into the discussion of matter, you should first observe the following example: Pak Sukirlan went to the market for Buy some kind of fruit. After shopping Pak Sukirlan then came home with two baskets. The first basket filled with fruit kelengkeng, duku, and rambutan. While the second basket is filled with guava, passion fruit, and rambutan. Arriving at home, the fruit is put into a large basket so that the big basket now contains a mixture of fruit bought by Sir Sukirlan namely kelengkeng, duku, rambutan, guava, and passion fruit. From the examples above, we can conclude that if both baskets carried by sir Sukirlan are the sets A and B. then, the composite of the set A and B are subsets whose members are members of the set A or members of the set B. or in mathematics can be written as: [(19459007) A B = A union B (A combined B) How To Determine The Combined Two Set 1.

[1945909] if A ⊂ C then A ∪ B = B

That is, when members Set A belongs to a member of set B (A is a subset of B) then the composite of both sets contains all members of set B.


2. Both The Equal Compound

if A = B then A ∪ B = A = B
[1945906]
Meaning that if member set A is exactly the same as a member of set B, then the composite of both sets contains members of set A or B.


3. The set is not mutually exclusive

For example A = 2, 3, 4, 6, 8 and B = 2, 5, 6, 9 then AUB = 2, 3, 4, 5, 6, 8, 9


The large number of members of a composite of two sets can be determined using the following formula:
[1945909]
n (A ∪ B) = n (A) + n (19459024) [1945907] Sample Problem:


X = 1, 2, 3, 4, 6, 8
Y = 2, 4, 5, 6, 9, 11

Determine:

a. Member X ∩ Y
b. Member X ∪ Y
c. n (X ∪ Y)


Answer:

a. X ∩ Y = 2, 4, 6
b. X ∪ Y = 1, 2, 3, 4, 5, 6, 8, 9, 11
c. n n (X ∪ Y) = n (X) + n (Y) - n [19459025(X∩Y)
n (X ∪ Y) = 6 + 6 - 3
n (X ∪ Y) = 9


A few explanations and examples of the question [P] the union of the Two Associations and the Way of Determining it may help you to understand more about the matter of the set. Until we meet the subject of further mathematics lessons.

Units of Size The number of Lusin, Gross, Rim, and Kodi

Unit Size The Number of Lusin, Gross, Rim, And Kodi - When carrying out your daily activities you must have heard some terms like Lusin, Gross, Rim, and Kodi in mathematics the term is called a unit of measure of quantity or quantity. This unit is commonly used to express the number of items or objects. For those of you who do not know or have not memorized by the size of the unit, let us study it together by listening to the discussion The Basic Mathematical Formula on the following unit size sums: The most commonly used unit of measure quantities is : 1 dozen = 12 pieces 1 gross = 144 pieces = 12 Lusin 1 score = 20 pieces ] 1 rim = 500 glue Bar The use of units of measure of the number of Lusin, Gross, Rim, and Kodi The above sizes are usually used in accordance with certain types of goods, for example: Lusin The term dozen is more often used to express the number of items such as glasses, plates, spoons, jars, and so on.

Example Problem Arithmetic Social About Discount / Rebate

Example Problem Arithmetic Social About Discount / Rebate - the meaning of rebates are rebates granted to a product or service. We are more familiar with rebates as a discount. You'll often see at the supermarket or supermarket there are a lot of rebates or discounts, it is an example of a rebate. If you are curious about how to calculate the price cuts, the Mathematical Formulas Basic will give his review to you through examples to the following: Example Problem Discussion and Arithmetic Social About Rabat Example Problem 1 Melly want to buy a dress for Rp 120,000. It turned out that the clothes receive a rebate of 20%. What is the size of the rebate? Answer: clothes Price: Rp 120,000 Rabat: 20% x 120,000 = 20/100 x 120,000 = 24,000 Thus, rabatnya amounted Rp.24.000 Example Problem 2 [1945901million] A Shop, gives a 5% discount for every purchase math book. If a math book has a price of Rp. 85,000. what is the price of the book after the discount?...
