The complement of set A, denoted by ​ A`, is the collection of all elements that belong to the universal set but are not part of set A. It's not necessary to mention the universe (also known as U) if it's understood which set of elements is being referred to.

The complement of a set A is the collection of all elements that belong to the universal set but not to set A. It is denoted as ​ A` and does not include any elements that are already in set A. The universal set, also known as U, contains all possible elements and is assumed to be known. Therefore, when referring to the complement of a set, it is not necessary to mention the universal set explicitly. The complement of a set is useful in determining the set of elements that are not part of a particular set, and it can be used in various mathematical operations.

After answering the presented question, we can conclude that equation Therefore, the answer is: 8 adults and 12 children went to the movies.

An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x Plus 3" equals the value "9." The purpose of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complicated, regular or nonlinear, and include one or more elements. In the equation "x2 + 2x - 3 = 0," for example, the variable x is raised to the second power. Lines are utilised in many different areas of mathematics, such as algebra, calculus, and geometry.

system of equations -

\(x + y = 20 \\9x + 6y = 144 \\x = 20 - y\\9(20 - y) + 6y = 144\\180 - 3y = 144\\-3y = -36\\y = 12\\x + 12 = 20\\x = 8\\\)

So there were 8 adults who went to the movies.

A condition that is impossible to satisfy has no solution.

Mathematics can be a powerful tool for solving many problems, but there are some issues that can't be solved.

In particular, any condition that is impossible to satisfy, such as the logical statement ‘this statement is false’, has no solution in mathematics. This is because the statement can’t be proven true or false, and so it can’t be solved.

An unsolvable condition is one that cannot be solved using any combination of logical and mathematical steps.

This means that no matter how much time and effort is put in, a solution to the problem cannot be discovered.

Converting .1515 which is a repeating nonterminating decimal to a fraction is: 5/33.

Given:

Decimal =0.1515

Let x represent the repeating and nonterminating number

In order to get the same recurring decimal  we would need to multiply the number by either 10, 100 or 1000.

Hence,

x=0.1515 equation 1

100z=0.1515 equation 2

Deduct equation 1 from equation 2

100x − x = 15.151- 0.1515

100x − x = (15 + 0.1515) − 0.1515

(100 − 1) x = 15 + 0

99 x = 15

Divide both side by 99x

x=15/99

Divide the numerator  which is 15 and the denominator which is 99 by 3

x= 5/33

Therefore converting .1515 which is a repeating nonterminating decimal to a fraction is: 5/33.

Answer:

\(a\neq 0 \text{ and } b\neq 0\)

Step-by-step explanation:

So we have the rational expression:

\(\frac{-12a^3b^5}{4a^2b^7}\)

In rational expressions, the restrictions of the expression would be the zeros of the denominator Therefore, set the denominator equal to zero and solve for its zeros:

\(4a^2b^7=0\)

Zero Product Property:

\(4a^2=0\text{ or } b^7=0\\\)

Solve for a and b:

\(4a^2=0 \text{ or } b^7=0\\a\neq 0 \text{ or }b\neq 0\)

Therefore, the restrictions on the variables are that a and b cannot equal zero.

Answer:

Set your calculator to Degree mode.

\( \alpha = {cos}^{ - 1} \frac{7}{8} \)

\( \cos(2 \alpha ) = \frac{7}{x} \)

\( \cos(2 {cos}^{ - 1} \frac{7}{8} ) = 2 {cos}^{2} ( {cos}^{ - 1} \frac{7}{8} ) - 1 = \frac{7}{x} \)

\(2( { \frac{7}{8}) }^{2} - 1 = \frac{7}{x} \)

\( \frac{17}{32} = \frac{7}{x} \)

\(17x = 224\)

\(x = \frac{224}{17} = 13.176\)

\( \alpha = {cos}^{ - 1} \frac{7}{8} = 28.955 \: degrees\)

A set is a collection of things, usually numbers. We can list each element (or "member") of a set inside curly brackets like this:

Here is a list of common symbols used in the set theory

Symbol Meaning Example

{ } Set: a collection of elements {1, 2, 3, 4}

A ∪ B Union: in A or B (or both) C ∪ D = {1, 2, 3, 4, 5}

A ∩ B Intersection: in both A and B C ∩ D = {3, 4}

A ⊆ B Subset: every element of A is in B. {3, 4, 5} ⊆ D

A ⊂ B Proper Subset: every element of A is in B,

but B has more elements. {3, 5} ⊂ D

A ⊄ B Not a Subset: A is not a subset of B {1, 6} ⊄ C

A ⊇ B Superset: A has same elements as B, or more {1, 2, 3} ⊇ {1, 2, 3}

A ⊃ B Proper Superset: A has B's elements and more {1, 2, 3, 4} ⊃ {1, 2, 3}

A ⊅ B Not a Superset: A is not a superset of B {1, 2, 6} ⊅ {1, 9}

Ac Complement: elements not in A Dc = {1, 2, 6, 7}

When set universal = {1, 2, 3, 4, 5, 6, 7}

A − B Difference: in A but not in B {1, 2, 3, 4} − {3, 4} = {1, 2}

a ∈ A Element of: a is in A 3 ∈ {1, 2, 3, 4}

b ∉ A Not element of: b is not in A 6 ∉ {1, 2, 3, 4}

Ø Empty set = {} {1, 2} ∩ {3, 4} = Ø

set universal Universal Set: set of all possible values

(in the area of interest)  

P(A) Power Set: all subsets of A P({1, 2}) = { {}, {1}, {2}, {1, 2} }

A = B Equality: both sets have the same members {3, 4, 5} = {5, 3, 4}

A×B Cartesian Product

(set of ordered pairs from A and B) {1, 2} × {3, 4}

= {(1, 3), (1, 4), (2, 3), (2, 4)}

|A| Cardinality: the number of elements of set A |{3, 4}| = 2

| Such that { n | n > 0 } = {1, 2, 3,...}

: Such that { n : n > 0 } = {1, 2, 3,...}

∀ For All ∀x>1, x2>x

For all x greater than 1

x-squared is greater than x

∃ There Exists ∃ x | x2>x

There exists x such that

x-squared is greater than x

∴ Therefore a=b ∴ b=a

Answer:

Step-by-step explanation:

Answer:

11%

Step-by-step explanation:

1. Fill out the table with the correct numbers.

2. After you fillout the numbers, you should notice that under the column car and in the first row, there should be the number 18.

3. We know the total number of students under the age of 15 is 165.

4. To find the percent:

       18/165 * 100

               = 11%

Answer:

41%

Step-by-step explanation:

Look at the column "Age 15 and above".

Notice how the row total for that column is 195.

Also, look at "Bus".

Notice how there is a gap between 60 and 110.

To calculate the answer, you need to fill in the blanks using the surrounding numbers.

60 + 50 = 110, so to the right of "65" on "Age 15 and above", there should be a 50.

The "195" at the end of the row is now on the same row as the numbers: 65, 50, and a blank spot.

Now, all we have to do is simply ask ourselves what 65 + 50 gets us, and what we need to add to that to get 195.

65 + 50 = 115, 115 + 80 = 195.

Although, notice that this does not mean the answer is not 80%.

We need to find what percentage is 80 out of 195.

80 out of 195 = 41.03%.

By rounding, we will get an answer of 41%.

Now lets put in 8 for x in our original equation:

8 / 2 - 1 = 3

4 - 1 = 3

3 = 3

The gradient of the function \(\(f\)\) at the point \(\((-1, -3)\)\) is:

\(\[\nabla f(-1, -3) = \left(-3e^{-3} \sin(12), 4e^{-3} \cos(12)\right)\]\)

To find the gradient of the function \(\( f(x, y) = e^{3x} \sin(4y) \)\) at the point \(\((-1, -3)\)\), we need to compute the partial derivatives with respect to \(\(x\) and \(y\)\) and evaluate them at that point.

The gradient of a function is given by:

\(\[\nabla f(x, y) = \left(\frac{{\partial f}}{{\partial x}}, \frac{{\partial f}}{{\partial y}}\right)\]\)

Let's calculate the partial derivatives:

\(\[\frac{{\partial f}}{{\partial x}} = \frac{{\partial}}{{\partial x}}\left(e^{3x} \sin(4y)\right) = 3e^{3x} \sin(4y)\]\)

\(\[\frac{{\partial f}}{{\partial y}} = \frac{{\partial}}{{\partial y}}\left(e^{3x} \sin(4y)\right) = 4e^{3x} \cos(4y)\]\)

Now, we can evaluate these derivatives at the point \(\((-1, -3)\):\)

\(\[\frac{{\partial f}}{{\partial x}}\Bigr|_{(-1, -3)} = 3e^{3(-1)} \sin(4(-3)) = 3e^{-3} \sin(-12)\]\)

\(\[\frac{{\partial f}}{{\partial y}}\Bigr|_{(-1, -3)} = 4e^{3(-1)} \cos(4(-3)) = 4e^{-3} \cos(-12)\]\)

Simplifying further:

\(\[\frac{{\partial f}}{{\partial x}}\Bigr|_{(-1, -3)} = 3e^{-3} \sin(-12) = -3e^{-3} \sin(12)\]\)

\(\[\frac{{\partial f}}{{\partial y}}\Bigr|_{(-1, -3)} = 4e^{-3} \cos(-12) = 4e^{-3} \cos(12)\]\)

Therefore, the gradient of the function \(\(f\)\) at the point \(\((-1, -3)\)\) is:

\(\[\nabla f(-1, -3) = \left(-3e^{-3} \sin(12), 4e^{-3} \cos(12)\right)\]\)

Given :

A college cafeteria pays student cashiers $540 per hour. Cashiers earn an additional  $110 per hour for each hour worked over 35 hours per week.

To Find :

A cashier worked 39  hours one week and 37 hours the second week.

Show and explain to the cashier how her salary calculated in this two-week period.

Solution :

Week 1 :

For first 35 hours he will get fixed amount i.e $540.

Now, for next four hours he will get $110 per hour.

So, total salary, T = 540 + (110×(39 - 35)

T = $980

Week 2 :

Total salary, T = 540 + ( 110×( 37 - 35 ))

T = $760

Therefore, salary of two week period is $( 980 + 760 ) = $1740.

The probability of drawing a seven and then a four when randomly drawing two cards without replacement is 0.0045 or approximately 0.45%.

The probability of drawing a seven and then a four when randomly drawing two cards without replacement can be calculated using the following steps:

First, we need to determine the total number of possible outcomes when drawing two cards from a standard deck of 52 cards without replacement. This can be found using the combination formula:

C(52,2) = 52! / (2! * (52-2)!) = 1,326

Next, we need to determine the number of favorable outcomes where we draw a seven and then a four.

There are four sevens and four fours in a deck of 52 cards, so the probability of drawing a seven on the first draw is 4/52. Since we are not replacing the card, there are now 51 cards left in the deck, and three of them are fours. Therefore, the probability of drawing a four on the second draw is 3/51.

The probability of drawing a seven and then a four is the product of the probabilities of drawing a seven on the first draw and a four on the second draw:

P(seven and then four) = (4/52) * (3/51) = 0.0045 or approximately 0.45%.

Therefore, the probability of drawing a seven and then a four when without replacement is 0.0045 or approximately 0.45%.
