To prove that the argument is valid using propositional logic, we can apply logical rules and deductions. Let's break down the argument step by step:

(A + B) ^ (C V -B) ^ (-D --> C) ^ A ^ D

We will represent the proposition as follows:

P: (A + B)

Q: (C V -B)

R: (-D --> C)

S: A

T: D

From the given premises, we can deduce the following:

P ^ Q (Conjunction Elimination)

P (Simplification)

Now, let's apply the rules of disjunction elimination:

P (S)

A + B (Simplification)

Next, let's apply the rule of disjunction introduction:

C V -B (S ^ Q)

Using disjunction elimination again, we have:

We ahve to solve for y in the equation:

- 2 x - 7 y = 4

We add 7 y to both sides:

- 2 x = 4 + 7 y

now subtract 4 from both sides:

- 2 x - 4 = 7 y

divide everything on the left and everything on the right by 7 in order to isolate the "y" completely:

- 2 x / 7 - 4 / 7 = y

y = -(2/7) x - (4/7)

where "- (2/7) " is the slope

and

"- (4/7)" is the y-intercept

The method that Roger's credit card company use is the average daily balance method.

(1) If Roger's company uses the previous balance method:

The total balance at the end of the month is:

P= 265.40+43.33+37.71= $346.44

The interest levied on this balance = 346.44*19.40/100 *1/12 = $5.60

(2)If Roger's company uses the adjusted balance method:

The total balance at the end of the month is:

P= 265.40+43.33+37.71-90= 256.44

The interest levied on this balance = 256.44*19.40/100 * 1/12 = $4.146

The average daily balance is a common accounting method that calculates interest charges by considering the balance invested or owed at the end of each day of the billing period, rather than the balance invested or owed at the end of the week, month, or year.

(3)if Roger's company uses the Daily balance method:

Balance up to 6/1 to 6/6 = 265.40 for 5 days

Balance up to 6/6 to 6/16 = 265.40-90 = 175.40 for 10 days

Balance up to 6/16 to 6/22 = 175.40+43.33. = 218.73 for 6 days

Balance upto 6/22 to 6/30 = 218.73+37.71 = 256.44 for 8 days

So average daily balance :

(265.40*5+175.40*10+218.73*6+ 256.44*8)/30= 214.83

The interest levied on this balance = 214.83*19.40/100 * 1/12= $3.47

Thus, the method that Roger's credit card company use is the average daily balance method.

Answer:

p(x), q(x), and their product are all polynomials.

p(x) · q(x) = 6x² + 10x - 63

Step-by-step explanation:

First of all P(x) and q(x) are polynomials because polynomials refer to any sum, difference, or product of a collection of algebraic terms. The word polynomials is general. P(x) and q(x) are polynomials but more specifically they are binomials since they only have two terms. Their product is a polynomial as well, but more specifically its a trinomial because it has three terms.

process of multiplying

Using the distributive property (or foil method) when multiplying p(x) and q(x) you would first get the expression 6x² - 18x + 28x - 63. From here you would combine "like terms". This would give you your final answer of

6x² + 10x - 63. Sorry, I couldn't help you with the D question but I hope this helps ;)

Rounding the answer to four decimal places, the WACC is approximately 0.0655.

To calculate the weighted average cost of capital (WACC), we need to consider the cost of equity, cost of debt, debt ratio, and tax rate.

Cost of equity = 0.09

Cost of debt = 0.05

Debt ratio = 0.58

Tax rate = 0.35

WACC is calculated using the formula:

WACC = (E/V) * Re + (D/V) * Rd * (1 - Tax rate)

Where:

E = Market value of equity

V = Total market value of equity and debt

Re = Cost of equity

D = Market value of debt

Rd = Cost of debt

Since we are not given the market values of equity and debt, we can use the debt ratio to determine the proportions of equity and debt in the capital structure.

Let's assume a total market value of $1, which means equity value is (1 - debt ratio) and debt value is (debt ratio).

WACC = ((1 - 0.58) * 0.09) + (0.58 * 0.05 * (1 - 0.35))

     = 0.42 + 0.01885

     ≈ 0.43885

Rounding the answer to four decimal places, the WACC is approximately 0.0655.

The distribution of the number of business majors you choose is not binomial. The correct option is c) not binomial.

The distribution of the number of business majors you choose is not binomial because the conditions for a binomial distribution are not met:

1. There must be a fixed number of trials: In this case, we are choosing 3 students out of 10, which means the number of trials is not fixed.

2. The trials must be independent: This assumption is reasonable, as choosing one student does not affect the probability of choosing another student.

3. The probability of success must be the same for each trial: The probability of choosing a business major is 0.4 for the first trial, but it will change for the second and third trials depending on the results of the previous trials. Therefore, the probability of success is not the same for each trial.

Therefore, the correct option is c) not binomial.

The complete question is:

In a group of 10 college students, 4 are business majors. You choose 3 of the 10 students at random and ask their major. The distribution of the number of business majors you choose is

Step-by-step explanation:

Answer:

C. \(y - 8 = -0.2 (x+10)\)

Step-by-step explanation:

Slope

So first we need to find the slope in order to answer the question. To find the slope, we need to choose any two points from the table.

The slope equation is \(m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\).

Let's use point (10,4) and point (15,3).

Now let's substitute those values into the slope equation. That gets to \(m = \frac{3-4}{15-10}\).

Now let's simplify that to \(m = \frac{-1}{5} = -\frac{1}{5}\). Therefore, the slope is \(-\frac{1}{5}\). In other words, it is also \(-0.2\).

Point-Slope Form

Now we need to plug in the numbers into the point slope form.

The point-slope form is \(y - y_{1} = m(x-x_{1})\).

Let's plug in the slope (m) into the equation. That gets to \(y - y_{1} = -0.2 (x-x_{1})\).

Now let's use (-10,8) in the equation since that's what it states in the problem. Doing that would lead to \(y - 8 = -0.2 (x--10)\). In other words, that is \(y - 8 = -0.2 (x+10)\).

Therefore, the answer has to be c. \(y - 8 = -0.2 (x+10)\).

Answer:

Step-by-step explanation:

Reading out 0.75 as "75 hundredths" gives us the fraction 75/100. The greatest common factor between 75 and 100 is 25, so dividing the numerator and denominator by 25 gives us an equivalent fraction in simplest form:

\(\frac{75}{100}\div\frac{25}{25} =\frac{3}{4}\)

a) To calculate the pressure at 12 hours of shut-in:

substitute the given values into the pressure buildup equation and solve for P(t=12).

b) Superposition in time is used in pressure buildup analysis by adding or summing the responses of multiple transient tests to analyze and interpret reservoir behavior and properties.

We have,

a) To calculate the pressure in the production well at 12 hours of a shut-in, we can use the equation for pressure transient analysis during shut-in periods, known as the pressure buildup equation:

P(t) = Pi + (Q / (4πKh)) * log((0.14ϕμCt(t + Δt)) / (Bo(ΔP + Δt)))

Where:

P(t) = Pressure at time t

Pi = Initial reservoir pressure

Q = Flow rate

K = Permeability

h = Reservoir thickness

ϕ = Porosity

μ = Viscosity

Ct = Total compressibility

t = Shut-in time (12 hours)

Δt = Time since the start of the flow period

Bo = Oil formation volume factor

ΔP = Pressure drop during the flow period

Given:

Pi = 3100 psi

Q = 200 STB/day

K = 45 md

h = 60 ft

ϕ = 15%

μ = 1.2 cp

Ct = 15x10^-6 psi^-1

Bo = 1.3 bbl/STB

t = 12 hours

Δt = 48 hours

ΔP = Pi - P(t=Δt) = Pi - (Q / (4πKh)) * log((0.14ϕμCt(Δt + Δt)) / (Bo(ΔP + Δt)))

Substituting the given values into the equation:

ΔP = 3100 - (200 / (4π * 45 * 60)) * log((0.14 * 0.15 * 1.2 * 15x\(10^{-6}\) * (48 + 48)) / (1.3 * (3100 - (200 / (4π * 45 * 60)) * log((0.14 * 0.15 * 1.2 * 15 x \(10^{-6}\) * (48 + 48)) / (1.3 * (0 + 48))))))

After evaluating the equation, we can find the pressure in the production well at 12 hours of shut-in.

b) Superposition in time is a principle used in pressure transient analysis to analyze and interpret pressure build-up tests.

It involves adding or superimposing the responses of multiple transient tests to simulate the pressure behavior of a reservoir.

The principle of superposition states that the response of a reservoir to a series of pressure changes is the sum of the individual responses to each change.

Superposition allows us to combine the information obtained from multiple tests and obtain a more comprehensive understanding of the reservoir's behavior and properties.

It is a powerful technique used in reservoir engineering to optimize production strategies and make informed decisions regarding reservoir management.

Thus,

a) To calculate the pressure at 12 hours of shut-in:

substitute the given values into the pressure buildup equation and solve for P(t=12).

b) Superposition in time is used in pressure buildup analysis by adding or summing the responses of multiple transient tests to analyze and interpret reservoir behavior and properties.

A- The least-squares equation for the given (x, y) data pairs is ŷ = 4.759 - 0.115x, rounded to three digits after the decimal.

B- The least-squares equation for the given (x, y) data pairs is ŷ = 1.505 + 0.461x, rounded to three digits after the decimal.

(a) To find the least-squares equation for the given (x, y) data pairs, we first calculate the means of x and y:

Mean of x = (2 + 3 + 5) / 3 = 3.333

Mean of y = (4 + 3 + 6) / 3 = 4.333

Next, we calculate the sample covariance of x and y and the sample variance of x:

Sample covariance of x and y = [(2 - 3.333)(4 - 4.333) + (3 - 3.333)(3 - 4.333) + (5 - 3.333)(6 - 4.333)] / 2

= -0.333

Sample variance of x = [(2 - 3.333)^2 + (3 - 3.333)^2 + (5 - 3.333)^2] / 2

= 2.888

Finally, we can use these values to calculate the slope and intercept of the least-squares line:

Slope = sample covariance of x and y / sample variance of x = -0.333 / 2.888 = -0.115

Intercept = mean of y - (slope * mean of x) = 4.333 - (-0.115 * 3.333) = 4.759

Therefore, the least-squares equation for the given (x, y) data pairs is ŷ = 4.759 - 0.115x, rounded to three digits after the decimal.

(b) Following the same steps as in part (a), we find:

Mean of x = (4 + 3 + 6) / 3 = 4.333

Mean of y = (2 + 3 + 5) / 3 = 3.333

Sample covariance of x and y = [(4 - 4.333)(2 - 3.333) + (3 - 4.333)(3 - 3.333) + (6 - 4.333)(5 - 3.333)] / 2

= 1.333

Sample variance of x = [(4 - 4.333)^2 + (3 - 4.333)^2 + (6 - 4.333)^2] / 2

= 2.888

Slope = sample covariance of x and y / sample variance of x = 1.333 / 2.888 = 0.461

Intercept = mean of y - (slope * mean of x) = 3.333 - (0.461 * 4.333) = 1.505

Therefore, the least-squares equation for the given (x, y) data pairs is ŷ = 1.505 + 0.461x, rounded to three digits after the decimal.

(d) To solve the least-squares equation from part (a) for x, we can rearrange the equation as follows:

x = (y - 4.759) / (-0.115)

Therefore, x = (-8.130y + 37.069), rounded to three digits after the decimal.

The probability that a randomly chosen Latin student is a sophomore is 6/19, so the m + n is 25.

New schools have 40% freshmen with all freshmen taking Latin, 30% are sophomores with 80% sophomores taking Latin, 20% are juniors with 50% juniors taking Latin, and 10% are seniors with 20% seniors taking Latin.

So, the total students taking Latin is,

= 40%*100% + 30%*80% + 20%*50% + 10%*20%

= 76% of all students.

Then, the students that taking Latin is sophomore,

= 30% * 80%

= 24%

So the probability of a randomly chosen Latin student is a sophomore is,

m/n = chance event occurs / total event

= 24% / 76%

= 6 / 19
