Please i don't understand set theory in mathematics

Mathematics
1 answer:
nordsb [41]3 years ago
6 0

Set theory is the mathematical theory of well-determined collections, called sets, of objects that are called members, or elements, of the set. ... The axioms of set theory imply the existence of a set-theoretic universe so rich that all mathematical objects can be construed as sets

For example, if A = {1, 2, 3} and B = {1, 2, 3, 4, 5} then A Í B (Í means is a subset of). If A = {1, 2, 4, 8}, then n(A) = 4. This is because n(A) means the number of members in set A. The universal set is the set of all sets.

Hello!

Experimental probability is the probability in relation to the data that has been collected. In this example, adding up the times spun we get 18 times spun. Where red was spun 6 times, this is 1/3 of what was done.

Our answer is B) 1/3.

Hope this helped!

Translate the point (15,32) using the rule (x,y) > (x +3, y - 7)
anzhelika [568]

Answer:

(18, 25 )

Step-by-step explanation:

The translation rule

(x, y ) → (x + 3, y - 7 )

means add 3 to the original x- coordinate and subtract 7 from the original y- coordinate, then

(15, 32 ) → (15 + 3, 32 - 7 ) → (18, 25 )

"Ten subtracted from the quotient of a number<br> and 5 is 18."
Anika [276]

Answer: n/5 - 10 = 18: this would be the equation. Your answer would be 140.

Step-by-step explanation: Let consider the number as ‘X’

Quotient of a number and 5 can be written as

                        X divided by 5

Ten subtracted from the quotient of a number and 5 can be written as

                       (X divided by 5)-10

Ten subtracted from the quotient of a number and 5 is 18 can be written as

                       (X divided by 5)-10=18

  By solving the above equation, find ‘X’

                       (X divided by 5) = 18 + 10

                    X/5=28

                       X = 28 x 5 = 140

Lashawn solved the equation below to the determine the solution 3x-8=-x+4(x-2)
miss Akunina [59]

Answer:

all real numbers

Step-by-step explanation:

3x-8 = -x + 4(x-2)

distributive property:

3x - 8 = -x + 4x-8

Combine like terms:

(add 3x to both sides)

-8 = -8

That means that x can be any number, because in the end, x will be canceled out from the equation.
