The Horton family subscribes to 3 premium channels. The total monthly subscription fee for the excel cable company is 48 dollars. The Horton family will save 24 dollars in one year by using the less expensive company.

(A) To find the number of premium channels for which the total monthly subscription fee for the excel and best cable companies will be the same, we set these two expressions equal to each other and solve for x:

32 + 8x = 26 + 10x

8x - 10x = 26 - 32

-2x = -6

x = 3

Therefore, the Horton family subscribes to 3 premium channels.

(B) The total monthly subscription fee for the excel cable company is 32 + 8 × 2 = 48 dollars if the Horton family subscribes to 2 premium channels. The total monthly subscription fee for the best cable company is 26 + 10 × 2 = 46 dollars if the Horton family subscribes to 2 premium channels.

Since the total monthly subscription fee for the best cable company is less than the total monthly subscription fee for the excel cable company, the Horton family should subscribe to the best cable company in order to spend less money.

(C) If the Horton family subscribes to the best cable company for one year, they will save 48 - 46 = 2 dollars per month. Over the course of one year, they will save 2 × 12 = 24 dollars.

Therefore, the Horton family will save 24 dollars in one year by using the less expensive company.

What is control chart?

Control chart is used to show how a process changes over time.

There are three lines in a control chart.

They are the central line for the average, upper line for the Upper Control Limit (UCL) and a lower line for the Lower Control Limit (LCL)

It is known that the highest performance of a process is obtained when it is between the LCL and the UCL.

That means to get the best result, samples needs to be concentrated near the centerline.

Using a system of equations to solve the problem, the candy distributor must mix 190 Kilograms of the 20% chocolate and 10 Kilograms of the 60% chocolate to create 200 Kilograms of a 22% fat-content chocolate.

A system of equations means two or more equations solved simultaneously.

They are known as simultaneous equations and can be solved graphically, by elimination, by substitution, or matrix.

The fat-content of one of the chocolate blend = 20%

The fat-content of the second chocolate blend = 60%

The expected mixture will have a fat-content = 22%

The total kilograms of the end mixture = 200 kilograms

Let the 20% fat-content chocolate = x

Let the 60% fat-content chocolate = y

x + y = 200 ... Equation 1

Solving for x, x = 200 - y

0.2x + 0.6y = 0.22(200)  ... Equation 2

By substitution in Equation 2:

0.2(200 - y) + 0.6y = 44

40 - 0.2y + 0.6y = 44

40 + 0.4y = 44

0.4y = 4

y = 10

x = 200 - y

x = 190 (200 - 10)

Based on the system of equations, 190 kilograms of the 20%-fat-content chocolate must be mixed with 10 kilograms of the 60% fat-content chocolate.

Answer:

To solve the equation f(x) = 3, we can set the expression for f(x) equal to 3 and then solve for x. In other words, we want to find the values of x that make the equation 5 - \frac{x}{r^2} + 5 + 6 = 3 true.

We can start by simplifying the left side of the equation by combining like terms. This gives us

5 - \frac{x}{r^2} + 5 + 6 = 5 + 5 - \frac{x}{r^2} + 6 = 10 - \frac{x}{r^2} + 6

Next, we set this expression equal to 3 and solve for x:

10 - \frac{x}{r^2} + 6 = 3 \quad \Rightarrow \quad 10 - 6 = 3 - \frac{x}{r^2} \quad \Rightarrow \quad \frac{x}{r^2} = 7

To solve for x, we can multiply both sides of the equation by r^2:

x = 7r^2

Therefore, the solutions to the equation f(x) = 3 are $x = 7r^2$. Note that this is a general solution, and it may not give all the possible values of $x$ that make the equation true. It's also possible that there are no solutions, depending on the value of $r$.

In the broadest sense, inverse functions are those that "reverse" one another.

Any function can be solved for by substituting one variable for another to discover the inverse of that function.

Below is an example to help you understand.

Find the inverse of h (x) = (4x + 3)/(2x + 5)

Solution

H (x) should be changed to Y.

h (x) = (4x+3)/(2x+5) y = (4x + 3)/(2x + 5)

Change the order of x and y.

⟹ x = (4y + 3)/ (2y + 5).

The following formula should be used to solve for y in the equation above:

⟹ x = (4y + 3)/ (2y + 5)

Divide both sides by (2y + 5)

⟹ x (2y + 5) = 4y + 3

Distribute the x evenly.

⟹ 2xy + 5x = 4y + 3

isolate y.

⟹ 2xy – 4y = 3 – 5x

⟹ y (2x – 4) = 3 – 5x

Divide through by 2x - 4 to obtain;

⟹ y = (3 – 5x)/ (2x – 4) (2x – 4)

Finally, swap out y for h - 1. (x).

⟹ h – 1 (x) = (3 – 5x)/ (2x – 4) (2x – 4).

What is p-hacking?

p-hacking is the misuse of statistical data to make a result statistically significant.

Heath analyzes his data using a bivariate correlation, as he previously planned; however, to his frustration, he quickly learns that his results are just short of being statistically significant.

Heath's main target is to make his result statistically significant.

He decides to try conducting a multiple-regression analysis instead and is pleased to see that with this method of data analysis, the results are statistically significant. Because the results were so similar, Heath doesn't bother reporting the bivariate correlation in his paper, as he thinks that clearly multiple regression was the correct test to run.

She Heath did not report the bivariate correlation in his paper, he is misusing the data to make his data statistically significant.

The quadratic equations 5x² + 20x + 20 = 0 and x² + 6x + 9 = 0 are the only correct equations having only one solution.

Quadratic equations has it highest power to the degree of two and they have two solutions that makes them true. The solutions could be different or similar ( which implies there is only one solution). From the question we shall concentrate on the equations which have similar solution or rather only one solution.

For the equation 5x² + 20x + 20 = 0;

we divide through by 5 to get;

x² + 4x + 4 = 0

x² + 2x + 2x + 4 = 0 {we group the terms}

x(x - 2) +2(x + 2) = 0 {factorize}

(x + 2)(x + 2) = 0

either; x + 2 = 0 or x + 2 = 0

x = -2 or x = -2 {which are the same solutions}

For the equation x² + 6x + 9 = 0;

x² + 3x + 3x + 9 = 0 {we group the terms}

x(x + 3) + 3(x + 3) = 0 {factorize}

(x + 3)(x + 3) = 0

either; x + 2 = 0 or x + 2 = 0

x = -2 or x = -2 {which are the same solutions}

Therefore, the quadratic equations 5x² + 20x + 20 = 0 and x² + 6x + 9 = 0 each have only one solution which are -2 and -3 respectively.
