18.75 inches is the length of the rectangle and 18.75 inches is the width of rectangle.

The area of Rectangle is length times of width.

The perimeter of a rectangle is 50 inches.

Perimeter=2(Length+Width)

Length=3W

Perimeter=50 inches

50=2(3W+W)

50=2(4W)

50=8W

Divide both sides by 8

50/8=W

W=6.25

Length=3(6.25)=18.75.

Hence, the length of rectangle is 18.75 inches and width is 6.25 inches.

According to the given statement, there were 58 children, 29 adults and 64 students.

Algebraically speaking, an equation is indeed a statement that establishes the equivalence of two mathematical equations.

Let there be x number of children, y number of students and x/2 number of adults. Forming the first equation based on number of students -

x + y + x/2 = 151 : Equation 1

Multiply equation 1 with 2

2x + 2y + x = 302 : Equation 2

3x + 2y = 302 : Equation 3

y = (302 - 3x)/2 : Equation 4

Forming second equation based on cost -

5x + 7y + 12x/2 = 1086 : Equation 5

Rewriting this equation

5x + 7y + 6x = 1086 : Equation 6

11x + 7y = 1086 : Equation 7

Keep the value of y from equation 4 in equation 7

11x + 7(302 - 3x)/2 = 1086

11x + (2114 - 21x)/2 = 1086

22x + 2114 - 21x = 2172

x = 2172 - 2114

x = 58

Now,

y = (302 - 3x)/2

y = (302 - 3×58)/2

y = 128/2

y = 64

Number of adults = 58/2

Number of adults = 29

Thus, there were 58 children, 29 adults and 64 students.

What are interior angles?

An Interior Angle is an angle inside a shape.

The basic polygonal shape of a triangle has three sides and three interior angles. It is one of the fundamental shapes in geometry . It has three connected vertices. Triangles can be divided into a variety of categories according on their sides and angles.

The sum of the diagonal internal angles in a triangle determines its outer angle.

And also,

In a triangle, the sum of the interior angles is always 180°.

So, x= 125 ( Because 63+62=125 ) , 180 - (63+62) =55 and 180-55=125

The solution to this problem is the p-value must be higher than 0.05.

A confidence interval in frequentist statistics is a range of estimates for an unobserved parameter. The most common confidence level for computing confidence intervals is 95%, however other levels, including 90% or 99%, are sporadically employed.

Here ,

In this given problem we can see confidence interval has 0 in it.

So,

Since the confidence interval comprises 0, the null hypothesis should be rejected.

When the p-value exceeds the level of significance, the null hypothesis is only rejected.

Since alpha=0.05 in this case, the p-value must be higher than 0.05.

Thus, the p-value must be higher than 0.05.

The measure of each of the acute angles of the right triangle is 32° and 58°.

A right triangle is a kind of triangle which has a right angle (90°) and two acute angles (less than 90°).

Let x = measure of one of the acute angles

If the measure of one acute angle of a right triangle is 6 less than twice the measure of the other acute angle, then

measure of the other acute angle = 2x - 6

The sum of all the angles of any triangle is equal to 180°. Hence,

90° + x + 2x - 6 = 180°

Solve for the value of x.

3x = 96

x = 32

Solve for the measure of the other acute angle.

2x - 6 = 2(32) - 6 = 58

Hence, the two angles are 32° and 58°.

Yes, the given expressions are equivalent.

What is the equivalent expression?

Expressions that are equivalent do the same thing even when they have distinct appearances. When we enter the same value for the variable, two algebraic expressions that are equivalent have the same value.

We have,

9(4 - x)

and 36 - 9x

Are these equivalent expressions?

9(4 - x) = 36 - 9x

36 - 9x = 36 - 9x

So, LHS = RHS = 36 - 9x

Therefore, the expression 9(4 - x) and 36 - 9x  are equivalent expressions.

A function is a mathematical expression that describes the relationship between an input and an output.

The function table is a visual, graded table with cells for input and cells for output that are organized into rows and columns.

Function tables have three variables components. There is the input, the function and the output. Function tables are created so that one of the three components is unknown and the other two serve as the clues to solving the table.

The rule of a function table is the mathematical operation that describes the relationship between the input and the output. The rule must be consistently applied to all input/output parts.

A traditional function table is made using two rows, with the top row being the input cells and bottom row being the ouput celss. Each column represents a signal input/output relationship.

Rises to the left; falls to the right

============================================================

Explanation:

The leading term is what determines the end behavior of any polynomial function.

The leading term has the largest exponent. The other terms will have no effect on the end behavior.

As x gets really large in the positive direction, so does x^3. But the -2 out front will flip to have y go to negative infinity.

Therefore:  [tex]\text{as x} \to \infty, \ \text{y} \to -\infty[/tex]

We can informally think of this as "falls to the right".

---------------------------

As x heads to the left, x^3 becomes further negative. But -2 out front makes -2x^3 to be positive.

So [tex]\text{as x} \to -\infty, \ \text{y} \to \infty[/tex] aka "rises to the left".

Whatever x does, y does the opposite. If x goes positive, then y goes negative and vice versa.

-------------------------

The end behavior is therefore

[tex]\text{as x} \to \infty, \ \text{y} \to -\infty\\\\\text{as x} \to -\infty, \ \text{y} \to \infty[/tex]

x and y are opposite.

We can summarize that notation as saying "rises to the left, falls to the right".
