Erik spends $680 for cable television service. The cable company offers a deal that promises Erik 3 free months of cable if he signs a contract with them for $40 per month.
Complete the equation below to find the number of months that Erik will have cable television service with this deal. Use m to represent the number of months.
Answer:
Step-by-step explanation:
The cable company offers Erik 3 free months of cable if he signs a contract with them for $40 per month. This means that Erik will pay for (m - 3) months of cable service, since he will get 3 months for free. So the cost of the cable service for (m - 3) months is:
Cost = $40 per month x (m - 3) months
Cost = $40m - $120
We know that Erik spent $680 for the cable television service. So we can set up an equation to relate the cost to the number of months:
$40m - $120 = $680
To solve for m, we can isolate the variable on one side of the equation:
$40m = $800
m = 20
Therefore, Erik will have cable television service for 20 months with this deal.

b. Make the least possible number of the additions of
plates to the figure so that the table has rotational
symmetry of order 4 around its center.
The figure has rotational symmetry of order 2 and to achieve rotational symmetry of order 4, three plates need to added.
Explain about symmetry?
Symmetry is a property of an object that describes how it appears identical after some transformation, such as reflection, rotation, or translation. It is an essential concept in mathematics, science, art, and many other fields.
There are several types of symmetry, including:
Reflectional symmetry (also called bilateral symmetry).
Rotational symmetry.
Translational symmetry.
According to the question:
a. The figure has rotational symmetry of order 2. This means that if we rotate the figure 180 degrees around its center, the figure will look exactly the same as it did before the rotation.
b. To achieve rotational symmetry of order 4, we need to add plates in such a way that the figure looks the same after a rotation of 90 degrees, 180 degrees, and 270 degrees around its center.
To achieve this, we can add three more plates to the figure, one in between each pair of existing plates, After adding these plates, the figure has rotational symmetry of order 4. We can see this by rotating the figure 90 degrees, 180 degrees, and 270 degrees around its center
so the figure has rotational symmetry of order 4. Therefore, we only needed to add three plates to the figure to achieve rotational symmetry of order 4 around its center.

write the equation of a line parallel to 12x+8y=-40 through the point (6,-3)
Answer: To find the equation of a line parallel to 12x + 8y = -40, we need to first rearrange the equation into slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
12x + 8y = -40
8y = -12x - 40
y = -1.5x - 5
So, the slope of the line is -1.5.
Since the line we want is parallel to this line, it will have the same slope, which is -1.5. Now we can use the point-slope form of a line to find the equation:
y - y1 = m(x - x1)
where (x1, y1) is the point through which the line passes, and m is the slope.
Substituting (6,-3) and -1.5 for x1, y1, and m respectively, we get:
y - (-3) = -1.5(x - 6)
y + 3 = -1.5x + 9
y = -1.5x + 6
So the equation of the line parallel to 12x + 8y = -40 through the point (6,-3) is y = -1.5x + 6.

Given that OA =3x+7y
OB = 5x+6y and CD =6x-3y
Explain the geometrical relationship between the straight lines AB and CD.
(I know its parallel but how to prove?)
With given linear equations of lines, the straight lines AB and CD are not parallel.
What is a linear equation?
In mathematics, a linear equation is an equation that can be written in the form:
y = mx + b
where "y" and "x" are variables, "m" is the slope of the line, and "b" is the y-intercept, which is the point where the line crosses the y-axis.
A linear equation represents a straight line on a graph and describes a linear relationship between two variables. The slope "m" determines how steep the line is, while the y-intercept "b" determines where the line crosses the y-axis.
Now,
To determine if the lines AB and CD are parallel, we need to compare their slopes. If the slopes are equal, then the lines are parallel.
The slope of a line is given by the coefficient of "x" in its equation when it is written in the form of y = mx + b, where "m" is the slope.
For line AB, we have:
OA = 3x + 7y
OB = 5x + 6y
Subtracting the equation for OA from the equation for OB, we get:
OB - OA = (5x + 6y) - (3x + 7y)
= 2x - y
So the slope of line AB is:
m_AB = (change in y) / (change in x) = -2 / 1 = -2
Now, for line CD, we have:
CD = 6x - 3y
So the slope of line CD is:
m_CD = (change in y) / (change in x) = -3 / 6 = -1/2
Since the slopes of line AB and line CD are not equal, i.e., m_AB ≠ m_CD, we can conclude that the lines are not parallel to each other.
Therefore, the geometrical relationship between the straight lines AB and CD is that they are not parallel to each other.

The probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years IS 0.528.
The binomial probability:The binomial probability formula is used to calculate the probability of getting exactly k successes in n independent trials, where each trial has only two possible outcomes (success or failure) and the probability of success is denoted as p. The formula is:
[tex]P(X=k) = C(n,k)\times p^k\times(1-p)^{(n-k)[/tex]Here we have
39.6% of consumers believe that cash will be obsolete in the next 20 years.
Let p be the probability that a consumer believes that cash will be obsolete
=> p = 39.6% or 0.396.
Then, the probability that a consumer does not believe that cash will be obsolete is q = 1 - p = 0.604.
We need to find the probability that less than 3 of the selected consumers believe that cash will be obsolete.
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)
Using the binomial probability formula, we have:
[tex]P(X = k) = C(n,k) \times p^k\times q^{(n-k)[/tex]
=> P(X = 0) = C(6, 0) × (0.396)⁰ × (0.604)⁶ = 0.048
=> P(X = 1) = C(6, 1) × (0.396)¹ × (0.604)⁵ = 0.18
=> P(X = 1) = C(6, 2) × (0.396)² × (0.604)⁴ = 0.3
P(X < 3) = 0.048 + 0.18 + 0.3 = 0.528
Therefore,
The probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years IS 0.528.

The answer of the given question based on the cost of mailing is , the cost of mailing a 2.5-ounce letter to Vienna, Austria would be $6.63 (rounded to the nearest cent).
What is Equation?An equation is mathematical statement that shows two expressions are equal. It contains variables, constants, and mathematical operations like addition, subtraction, multiplication, and division.
For example, a simple equation could be:
2x + 3 = 9
The equation y = 0.25x + 6.00 represents the cost y of mailing a letter to Vienna, Austria based on the weight x of the letter in ounces. The flat rate of $6.00 is represented by the constant term 6.00 in the equation, and the additional charge of $0.25 per ounce is represented by the coefficient of x, which is 0.25.
To use this equation to determine the cost of mailing a specific letter, you would need to know the weight of the letter in ounces. You could then substitute this value for x in the equation and solve for y, which would give you the cost of postage in dollars.
For example, if a letter weighs 2.5 ounces, you could plug in x = 2.5 into the equation:
y = 0.25(2.5) + 6.00
y = 0.625 + 6.00
y = 6.625

While a W-2 form contains a lot of important information about an employee's earnings and tax withholding, it does not include every detail about their employment or financial situation. Some examples of information that are not included on a W-2 form include:
Information about non-wage income, such as interest or dividends
Information about benefits received, such as health insurance or retirement plan contributions
Information about deductions or credits, such as charitable contributions or education expenses
Information about stock options or other forms of equity compensation
Information about expenses related to employment, such as travel or equipment costs.

1. The proportion, p, of consumers who shop with coupons
is the ratio of the number, C, of consumers who use coupons
to the number, N, of consumers asked. Write an equation
for the proportion of consumers who shop with coupons.
The equation for the proportion, p, of consumers who shop with coupons is: p = C/N where C is the number of consumers who use coupons and N is the total number of consumers asked.
What is equation?An equation is a mathematical statement that indicates the equality of two expressions. It consists of two expressions separated by an equal sign (=). The expression on the left side of the equal sign is equivalent to the expression on the right side. Equations can have one or more variables, which are usually represented by letters such as x, y, or z. The goal in solving an equation is to determine the value(s) of the variable(s) that make the equation true. This involves manipulating the expressions on both sides of the equal sign using algebraic operations such as addition, subtraction, multiplication, and division, to isolate the variable on one side of the equation. Equations are used in many areas of mathematics and science to represent relationships between variables and to solve problems. They are also used in various fields such as engineering, physics, and economics to model real-world situations and make predictions based on mathematical analysis.

Suppose your boss proposes an alternative form of payment. For the first day of each month, you’ll earn a penny. Thereafter, each workday your wages will double what they were the day before. If there are 20 workdays in a month, how much would you make for the month?
We will make ₹1,048,575 for the month. The solution has been obtained by using the arithmetic operations.
What are arithmetic operations?The four basic operations, often referred to as "arithmetic operations", are thought to be able to describe all real numbers. Divide, multiply, add, and subtract are the four mathematical operations that result in the quotient, product, sum, and difference.
We are given that for the first day of each month, a penny is earned. Thereafter, each workday wages will double what they were the day before.
Now, since there are 20 workdays in a month so, the total amount earned is as follows:
⇒ 1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 + 512 + 1,024 + 2,048 + 4,096 + 8,192 + 16,384 + 32,768 + 65,536 + 131,072 + 262,144 + 524,288

The radical expression (6–√4)3 written in exponential form is 612.
What is expression?Expression is a term used to describe the process of making clear or conveying one's thoughts, ideas, and feelings. It is a way of communicating with others and expressing oneself in a meaningful and effective manner. Expression can be done through verbal and non-verbal communication, including writing, art, music, dance, and other creative outlets. It can also be used to express emotions such as joy, sadness, fear, anger, and love. Expression is essential to healthy communication and can be a powerful tool for self-expression, personal growth, and development.
This is because raising a number to an exponent is the same as multiplying that number by itself the number of times specified by the exponent. In this case, the base number is 6, and the exponent is 12. When a number is multiplied by itself 12 times, it is referred to as an exponential expression. To convert the radical expression to an exponential expression, the radical needs to be converted to an exponent. The radical of 4 is 2, so the exponent is 12. This results in the answer 612.

the positive value of "x" for the given quadratic equation will be 5.
What is a Quadratic equation?ax²+bx+c=0, with a not, equals 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
Given a quadratic equation, √(4x² - 4x + 1) = 9
Simplifying the value of the given equation to calculate the value of the variable "x",
Equation,
=> √(4x² - 4x + 1) = 9
Square both sides
=> (4x² - 4x + 1) = 81
=> 4x² - 4x - 80 = 0
Divide by 4 into both sides of the equation,
=> x² - x -20 = 0
Simplifying the equation using the factorization method,
=> x² - 5x + 4x - 20 = 0
=> x(x - 5) + 4(x - 5) = 0
=> x = -4
=> x = 5

A capsule manufacturing company is having difficulty filling capsules to the required 100 milligrams. Suppose a business researcher randomly selects 80 capsules, weighs each of them and computes its mean. By chance, the researcher selects capsules that have been filled adequately and that is how he gets the mean weight of 100 mg, which falls in the "fail to reject" region. The decision is to fail to reject the null hypothesis even though population mean is NOT actually 100 mg. Which kind of error has the researcher done in this case?
Using null hypothesis, we can find that the researcher has done type II error in this case.
What is null hypothesis?Hypothesis testing uses sample data from the population and draws conclusions about the population's probability distribution. It looks at a data assumption and uses a variety of methods for testing assumptions. The null hypothesis is rejected or not according to the results of the hypothesis test.
The chance of rejecting the null hypothesis when it is true is what is meant by type I error.
Probability of adopting the null hypothesis when it is untrue is the definition of type II error.
Here, CAPSULES is not actually 100 Mg and you have taken the decision of fail to reject the null hypothesis, (which means that accepting the null hypothesis) so, this is a type II error.
