Answer:

5. Supplier A are cheaper because they offered discounts and the shipping fees more cheaper.

6. $212.09

Step-by-step explanation:

Supplier A:

= $1560 in total for uniforms only

= $1326 in total after discount

= $1412.19 after tax included

= $1427.19 in total included shipping fee

Supplier B:

= $1455 in total for uniforms only

= $1549.58 in total included tax

= $1639.28 in total included shipping fee

$1639.28 - $1427.19 = $212.09

The value of measure of ''angle f'' in the figure will be 46°.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

In the figure,

The value of angle a and e are;

⇒ a = 115°

⇒ e = 69°

Now,

Since, There are two parallel lines shown in figure.

Hence, We know by the definition of alternate angles of parallel lines,

⇒ ∠a = ∠f + ∠e

Here, We have to given that;

The angles are,

⇒ a = 115°

⇒ e = 69°

So, We get by substitute the value of angle a and e;

⇒ ∠a = ∠f + ∠e

⇒ 115° = ∠f + 69°

Subtract 69° both side, we get;

⇒ ∠f = 115° - 69°

⇒ ∠f = 46°

Thus, The value of measure of angle f;

⇒ ∠f = 46°

Paul's pig pen has a width of 2 feet and an area of 16 square feet is the true statement.

The area of Rectangle is length times of width.

This is a simple calculus problem but it can be solved without calculus, as follows:

let L=length of the pen and W = width

2(L + W) = 20  

L + W = 10

L = 10 - W

Let A = area of the pen

A = Length × Width = 10W - W²

Sketch this parabola which has a positive maximum which occurs at W = 10/2

This means the area is maximum when w = 2, in other words the maximum area occurs when the rectangle is a square.

Area of the parallelogram is 96 \(cm^{2}\).

Step-by-step explanation:

A parallelogram is a quadrilateral with parallel and equal length of opposite sides. The diagonals are perpendicular to each other.

Area of a parallelogram is given as,

Area = base x height

Thus for the given parallelogram with base 12 cm and height 8 cm, the area would be;

Area = base x height

        = 12 x 8

        = 96

Area = 96 \(cm^{2}\)

The area of the parallelogram is 96 \(cm^{2}\).

Answer:

Let's start by assigning some variables to the unknowns:

Let's call the price of one taco "t".

Let's call the price of one burrito "b".

With these variables, we can write two equations based on the information given in the problem:

5t + 2b = 13.25 (equation 1)

3t + 2b = 10.75 (equation 2)

We now have two equations and two variables. We can use algebra to solve for t and b. One way to do this is to eliminate b by subtracting equation 2 from equation 1:

(5t + 2b) - (3t + 2b) = 13.25 - 10.75

Simplifying this equation, we get:

2t = 2.5

Dividing both sides by 2, we get:

t = 1.25

So the price of one taco is $1.25.

Now that we know the price of one taco, we can substitute this value into one of the equations to solve for b. Let's use equation 1:

5t + 2b = 13.25

Substituting t = 1.25, we get:

5(1.25) + 2b = 13.25

Simplifying this equation, we get:

6.25 + 2b = 13.25

Subtracting 6.25 from both sides, we get:

2b = 7

Dividing both sides by 2, we get:

b = 3.5

So the price of one burrito is $3.5.

Therefore, the price of one taco is $1.25 and the price of one burrito is $3.5.

A qualitative problem statement is one that identifies and defines an issue or challenge using qualitative research techniques. A good qualitative problem statement should define both the independent and dependent variables while conveying a sense of emerging design and specifying a specific hypothesis to be tested.

Additionally, it should specify a relationship between the independent and dependent variables. The problem statement must be clear and concise, providing enough context for the reader to understand the research problem.In a qualitative research study, the researcher may not have a hypothesis and instead may use the problem statement to frame the research questions. In this case, the problem statement should still identify the independent and dependent variables and convey a sense of emerging design.

For example, a qualitative problem statement for a study on the experience of low-income students in higher education might read as follows: The purpose of this study is to explore the relationship between socioeconomic status and academic success among low-income college students. In this example, the independent variable is socioeconomic status, and the dependent variable is academic success.

The problem statement conveys a sense of emerging design by indicating that the study will explore the relationship between these two variables, rather than testing a specific hypothesis.

Answer:

x=-4, y=-1

Step-by-step explanation:

Given the following system of equations, solve the system using elimination.

\(\left \{ {{-2x-y=9} \atop {2x-9y=1}} \right.\)

(1) - Add the equations together

\(\left\begin{array}{ccc}&-2x-y=9\\+&2x-9y=1\end{array}\right\\\\\Longrightarrow -10y=10\\\\\therefore \boxed{y=-1}\)

Notice how the x term was eliminated, hence the name for this method is "elimination."

(2) - Take the value we just found for y and plug it into either of the two equations and solve for x

\(2x-9y=1\\\\\Longrightarrow 2x-9(-1)=1\\\\\Longrightarrow 2x+9=1\\\\\Longrightarrow 2x=-8\\\\\therefore \boxed{x=-4}\)

(3) - Thus, the system is solved. When x=-4, y=-1.

The inverse of a function swaps the domain and range.

The inverse of the function h(x) is

B. h'(x) = ((-5, 3), (-7, 5), (-9, 6), (-12, 10), (-16, 12)}

Option B is the correct answer.

We have,

The function h(x) is given as:

h(x) = {(3, -5), (5, -7), (6, -9), (10, -12), (12, -16)}

To find h¹(x) (the inverse of h(x)), we need to swap the x and y values in each ordered pair.

The inverse function will have the y-values of h(x) as the x-values, and the x-values of h(x) as the y-values.

So,

h¹(x) would be:

h¹(x) = {(-5, 3), (-7, 5), (-9, 6), (-12, 10), (-16, 12)}

A quadratic function has the generic form f(x)=ax²+bx+c. A parabola, a kind of two-dimensional curve, is the graph of a quadratic function. A polynomial function of degree two in one or more variables is known in algebra as a quadratic function, quadratic polynomial, polynomial of degree 2, or simply a quadratic. The phrase "quadratic" in mathematics refers to something that has to do with squares, the squaring operation, terms of the second degree, or equations or formulas that contain such terms. Latin's word for square is quadratus.

Function:

2x² + 4x + 7 = 0

ax² + bx + c = 0

x = \(\frac{-b +-\sqrt{}b^{2}- 4ac }{2a}\)

a = 2

b = 4

c = 7

Using quadratic function,

x = \(\frac{-4\sqrt{} 4^{2} -4(2)(7)}{2(2)}\)

x = \(\frac{-4+-\sqrt{-40} }{4}\)

So,

i = √-1

x = \(\frac{-4+-2i\sqrt{10} }{4}\)

Simplifying,

x = -1 +-√10/2

Roots are:

x = -1 + i√10/2

x = -1 - i√10/2

The sampling procedure being used to collect completion time data in this scenario is based on paired samples or dependent samples.

In paired samples, each observation in one sample is uniquely linked or paired with an observation in the other sample. In this case, the workers are randomly selected, and each worker is assigned to use both production methods, one after the other. The completion time for each worker is measured under both methods, creating paired or dependent observations.

By using paired samples, the company can compare the completion times of the same workers using different production methods. This approach helps eliminate individual differences and other sources of variability among workers, focusing solely on the comparison between the two methods.

The online poll asking the preferred mobile phone type used by school children is an observational study, not an experimental study, and there is no controlled factor involved.

An online poll asking the preferred mobile phone type used by school children would be considered an observational study. This is because the researcher is not actively manipulating any variables or treatments. Instead, they are simply observing and collecting data on the preferences of school children.
If the study were to be designed as an experiment, the controlled factor would be the type of mobile phone being offered as an option in the poll. For example, the researcher could randomly assign some participants to see only options for Apple iPhones, while others would only see options for Samsung Galaxy phones. By controlling the options presented to participants, the researcher could test whether there is a difference in preference for different types of mobile phones among school children.
However, it is important to note that an experiment of this nature may not be feasible or ethical. It may be difficult to limit the options presented to participants in an online poll, and doing so could potentially bias the results. Additionally, it may not be ethical to limit the options presented to participants, as it could be seen as withholding information or forcing a particular preference on them. Therefore, an observational study would likely be a more appropriate and ethical approach to studying the preferences of school children for mobile phones.
