Suppose X And Y Are Non-empty Sets. Which Set Contains More Elements: X U Y Or X Y? Explain. (2024)

Mathematics College

Answers

Answer 1

Answer:

The union of two sets is guaranteed to result in an equal or larger set than if they were intersected.

This only makes sense because intersecting sets is exceptional, only values that already exist in both sets are in the result. Whereas a union of two sets gives you all of the content of both.

The only time when an intersection is even equal to a union is when the two sets are identical. If they aren't then the intersection will be smaller.

What is the area of an rectangle with sides lengths of 5/12 foot and 2/3 foot

Answers

Answer:

The area of given rectangle is 5/18 square feet.

Step-by-step explanation:

Let l be the length of rectangle and w be the width of the rectangle.

Given information is:

Length = l = 5/12 foot

Width = w = 2/3 foot

The area of a rectangle is given by the formula

[tex]Area = Length*Width\\A = l*w[/tex]

Putting the values for width and length

[tex]A = \frac{5}{12} * \frac{2}{3}\\= \frac{10}{36}\\=\frac{5}{18}[/tex]

The area is 5/18 square feet.

Hence,

The area of given rectangle is 5/18 square feet.

Answer:

The perimeter of a rectangle is the sum of twice the length and twice the width. If the perimeter is at least 48 cm, then the minimum perimeter is 48 cm.

Let width = x

Let length = x + 4

Perimeter = 48

We can set an inequality for perimeter using the variables.

2x + 2(x + 4) ≥ 48

Solve for x.

2x + 2x + 8 ≥ 48

4x + 8 ≥ 48

4x ≥ 40

x ≥ 10

Substitute this value of x into the variable to get your width and length.

width = 10 cm

length = 14 cm

Answer:

S. 4

M. 2

S. 5

M. 8

And the graphing you just do those as m/s -->(M,S)

You can put the value of m or s in the given equation of m and s to obtained the missing value.

The completed table would look like:

[tex]\begin{array}{ccccc}m & 0 & 2 & -2 & 8\\s & 4 & 3 & 5 & 0\end{array}[/tex]

Simplifying the relation between m and s:

[tex]2m + 4s = 16\\\\\text{Dividing by 2 on both sides}\\\\\dfrac{2m + 4s}{2} = \dfrac{16}{2}\\\\m + 2s = 8[/tex]

How to evaluate the missing values?

Use one of the given value and the equation to find the missing value:

For m = 0:

[tex]m + 2s = 8\\0 + 2s = 8\\2s = 8\\\\s = \dfrac{8}{2}\\\\s = 4[/tex]

For s = 3:

[tex]m + 2s = 8\\m + 2 \times 3 = 8\\m = 8 - 6\\m = 2[/tex]

For m = -2:

[tex]m + 2s = 8\\-2 + 2s = 8\\2s = 10\\\\s = \dfrac{10}{2} \\\\s= 5[/tex]

For s= 0:

[tex]m + 2s = 8\\m + 2 \times 0 = 8\\m = 8[/tex]

Thus, the completed table would be:

[tex]\begin{array}{ccccc}m & 0 & 2 & -2 & 8\\s & 4 & 3 & 5 & 0\end{array}[/tex]

Suppose you buy a $50 coffee maker in an area where the sales tax is 8%. When you check out, 8% of $50 would be added to your total price. How much would you pay total? please help me with this question since this is due tommorow and I will get a 0% if it's not on time

Answers

Answer:

you will have to pay a total of 54$

Step-by-step explanation:

50$ : 100% = x : 108% (+8% for the tax 100+8+108)

100x = 108 x 50

100x = 5400

5400 ÷ 100 = 54

Total 54 $

The total money paid to buy a coffee maker is $54.

Given that, the cost of a coffee maker=$50 and the sales tax=8%.

We need to find the total cost of a coffee maker.

What is a sales tax?

A sales tax is a tax paid to a governing body for the sales of certain goods and services. Usually, laws allow the seller to collect funds for the tax from the consumer at the point of purchase.

Sales tax is an amount of money, calculated as a percentage, that is added to the cost of a product or service when purchased by a consumer at retail.

Now, the total money paid=50+8% of 508% of 50 can be calculated as 0.08×50=4

So, 50+4=$54

Therefore, the total money paid to buy a coffee maker is $54.

Suppose X And Y Are Non-empty Sets. Which Set Contains More Elements: X U Y Or X Y? Explain. (2024)

FAQs

Does the union of two sets have more elements than the intersection of two sets? ›

No. The intersection of two sets can never have more elements than the minimum of their cardinalities. Conversely, the union of two sets can never have less elements than the maximum of their cardinalities. Therefore the intersection can never have more elements than the union.

What refers to two or more sets with the same elements? ›

Equal sets are defined as the sets that have the same cardinality and all equal elements. In other words, two or more sets are said to be equal sets if they have the same elements and the same number of elements. For example set A = {1, 2, 3, 4, 5} and B = {1, 2, 3, 4, 5}.

Which two sets contains only the elements that are in both sets? ›

The intersection of two sets contains only the elements that are in both sets. The intersection is notated A ⋂ B. More formally, x ∈ A ⋂ B if x ∈ A and x ∈ B. The complement of a set A contains everything that is not in the set A.

What is an example of a non empty set? ›

In other words, a non-empty set is not empty; it has some elements in it. Mathematically, if you have a set denoted as "A ," and A is non-empty, it means that A contains one or more elements. For example, the set {1,2,3} { 1 , 2 , 3 } is a non-empty set because it contains the elements 1,2 , and 3 .

What is the difference between empty set and set containing empty set? ›

Another way to see at this is by looking at the number of elements in the sets: by definition, the empty set has zero elements, while the set containing the empty set has one element.

What is the difference between union and intersection of sets? ›

What is the difference between union and intersection? A union of sets produces a new set containing each element present in the original sets. An intersection of sets produces a new set that contains only the elements that the original sets have in common.

What is the difference between the union and the intersection of two or more events? ›

A union refers to an area that is said to be belonging to one or both of two events. In contrast, an intersection is an area that is said to be belonging to both of those two events. You can write down the union of two events as A∪B. On the other hand, you can write down the intersection of two events as A∩B.
