Procter and Gamble (PG) paid an annual dividend of $2.95 in 2018. You expect PG to increase its dividends by 7.4% per year for the next five years (through 2023), and thereafter by 2.6% per year. If the appropriate equity cost of capital for Procter and Gamble is 8.6% per year, use the dividend-discount model to estimate its value per share at the end of 2018.

Answers

The dividend in 2018 was $2.95, and it is expected to grow at a rate of 7.4% for the next five years and 2.6% thereafter. With an equity cost of capital of 8.6%, the value per share at the end of 2018 can be calculated.

To calculate the value per share at the end of 2018, we need to discount the expected future dividends using the dividend-discount model. The model assumes that the value of a stock is equal to the present value of all its expected future dividends.

First, we need to calculate the dividends for each year from 2019 to 2023. We start with the dividend in 2018, which was $2.95. We then increase it by 7.4% each year for the next five years:

Dividend in 2019 = $2.95 * (1 + 7.4%) = $3.17

Dividend in 2020 = $3.17 * (1 + 7.4%) = $3.40

Dividend in 2021 = $3.40 * (1 + 7.4%) = $3.65

Dividend in 2022 = $3.65 * (1 + 7.4%) = $3.92

Dividend in 2023 = $3.92 * (1 + 7.4%) = $4.22

After 2023, the dividend is expected to grow at a rate of 2.6% per year. To find the value per share at the end of 2018, we discount the future dividends to their present value using the equity cost of capital of 8.6%.

The present value of the dividends can be calculated as follows:

PV = (D1 / (1 + r)) + (D2 / (1 + r)^2) + ... + (Dn / (1 + r)^n)

where PV is the present value, D1 to Dn are the dividends for each year, r is the equity cost of capital, and n is the number of years.

In this case, n = 5 because we are discounting the dividends for the next five years. Let's calculate the present value:

PV = ($3.17 / (1 + 8.6%)) + ($3.40 / (1 + 8.6%)^2) + ($3.65 / (1 + 8.6%)^3) + ($3.92 / (1 + 8.6%)^4) + ($4.22 / (1 + 8.6%)^5)

PV = $3.17 / 1.086 + $3.40 / 1.086^2 + $3.65 / 1.086^3 + $3.92 / 1.086^4 + $4.22 / 1.086^5

PV ≈ $2.91 + $3.07 + $3.24 + $3.41 + $3.59

PV ≈ $16.22

Therefore, the estimated value per share of Procter and Gamble at the end of 2018 using the dividend-discount model is approximately $16.22.

b. if a is a 35 matrix and t is a transformation defined by t(x)ax, then the domain of t is .

Answers

For the matrix the true statement is given by option d. Both A and B are false.

Let's analyze each statement of the matrix as follow,

A) If A is a 3 times 5 matrix and T is a transformation defined by T(x) = Ax, then the domain of T is R⁵.

This statement is false.

The domain of the transformation T is not R⁵.

The domain of T is determined by the dimensionality of the vectors x that can be input into the transformation.

Here, the matrix A is a 3 times 5 matrix, which means the transformation T(x) = Ax can only accept vectors x that have 5 elements.

Therefore, the domain of T is R⁵, but rather a subspace of R⁵.

B) If A is a 3 times 2 matrix, then the transformation x right arrow Ax cannot be onto.

This statement is also false.

The transformation x → Ax can still be onto (surjective) even if A is a 3 times 2 matrix.

The surjectivity of a transformation depends on the rank of the matrix A and the dimensionality of the vector space it maps to.

It is possible for a 3 times 2 matrix to have a rank of 2,

and if the codomain is a vector space of dimension 3 or higher, then the transformation can be onto.

Therefore, as per the matrix both statements are false, the correct answer is d. Both A and B are false.

What is a concave hexagon with 2 pairs of congruent sides?

Answers

A concave hexagon with 2 pairs of congruent sides is a shape that has six sides and two pairs of sides that are of equal length, but the shape curves inward at one or more angles, creating a concave indentation.

A hexagon is a six-sided polygon, and when two pairs of its sides are congruent,

it means that four of its sides have the same length, if the shape curves inward at one or more angles,

it creates a concave hexagon, which means that the indentation on the shape is facing inward, rather than outward, a concave hexagon with 2 pairs of congruent sides is a six-sided polygon with four sides of equal length, but with a curvature that creates an inward indentation.

Hence, a concave hexagon with 2 pairs of congruent sides is a six-sided figure with an indentation and two sets of sides with equal lengths.

mary drove 156156 miles at a constant rate. if she had driven 99mi/h faster, she could have reduced her driving time by 4545 minutes. find the rate at which she actually drove.

Answers

The speed at which Marry was initially driving was 13 miles per hour and with that speed Marry drove 156 miles.

Given, Marry drove 156 miles at a constant rate.

If she had driven 99 miles/hour faster, she could have reduced her driving time by 45 minutes.

we have to find the speed at which Marry was driving.

Let the speed be, v

On using the distance formula, we get

Distance = Speed × Time

156 = vt

If she drive 99 miles/hour faster then her time reduced by 45 min.

156 = (v + 99)(t - 3/4)

156 = 156 + 99t - 3/4v - 297/4

396t = 3v + 297

396t = 468/t + 297

On solving the quadratic equation, we get

t = 12

and v = 13

So, the speed of marry was 13 miles per hour.

Hence, Initially the speed of marry was 13 miles per hour and with that speed Marry drove 156 miles.

Scenario: A small business owner needs to analyze their sales data to make informed decisions about pricing and profitability.

Supporting Detail 1: The concept of linear equations can be applied to determine the break-even point and set optimal pricing strategies for the business.

Worked Example 1: Let's say the small business sells a product for $10 each, and the fixed costs (expenses that don't vary with the number of units sold) amount to $500. The variable costs (expenses that depend on the number of units sold) are $2 per unit. We can use the formula for a linear cost equation (C = mx + b) to find the break-even point where revenue equals total costs:

10x = 2x + 500

Simplifying the equation, we get:

8x = 500

x = 500/8

x = 62.5

The break-even point is 62.5 units. Knowing this information, the business owner can make decisions about pricing, cost control, and production targets.

Supporting Detail 2: The concept of systems of equations can be applied to optimize the allocation of resources in the business.

Worked Example 2: Let's consider a scenario where the business owner sells two different products. Product A generates a profit of $5 per unit, while Product B generates a profit of $8 per unit. The business owner has a limited budget of $500 and wants to determine the optimal allocation of resources between the two products. We can set up a system of equations to represent the profit constraints:

x + y = 500 (total budget)

5x + 8y = P (total profit, represented as P)

By solving this system of equations, the business owner can find the optimal values of x and y that maximize the total profit while staying within the budget constraints.

Conclusion: Applying concepts from this algebra course to real-life scenarios, such as analyzing sales data for a small business, helps in understanding the material by providing practical applications. It demonstrates the relevance of algebra in making informed decisions, optimizing resources, and maximizing profitability.

These examples highlight how algebraic concepts enable problem-solving and provide valuable tools for individuals in various fields, including business and entrepreneurship.

Here we see that the square has an area of 8x8= 64 centimeters square. We want to subtract the area of the white part from 64 to find the area of the yellow region. If we were to put the white parts together it would create a circle, so we need to find the area of the circle and then subtract it from 64.

4.5kg of bananas and 3.5kg of apples cost £6.75. ^kg of apples cost £5.40. Calculate the cost of 1kg of bananas.

Answers

Answer: Let's assume the cost of 1 kilogram of bananas is represented by 'x'.

According to the given information, 4.5 kg of bananas and 3.5 kg of apples together cost £6.75. We also know that the cost of 1 kg of apples is £5.40.

Using this information, we can set up the following equation:

4.5x + 3.5(£5.40) = £6.75

Now let's solve for 'x':

4.5x + 3.5(£5.40) = £6.75

4.5x + £18.90 = £6.75

4.5x = £6.75 - £18.90

4.5x = -£12.15

x = (-£12.15) / 4.5

x ≈ -£2.70

The cost of 1 kilogram of bananas, based on this calculation, is approximately -£2.70. However, it's important to note that a negative cost doesn't make sense in this context. It's possible there may be an error in the given information or the setup of the equation.

Step-by-step explanation:

Given:

Distribute 12 in x-7:

\(\displaystyle \large{12x-84=-11}\)

Add both sides by 84:

\(\displaystyle \large{12x-84+84=-11+84}\\\displaystyle \large{12x=73}\)

Divide both sides by 12:

\(\displaystyle \large{\dfrac{12x}{12}=\dfrac{73}{12}}\\\displaystyle \large{x=\dfrac{73}{12}}\)

Therefore, the solution is x = 73/12

Answer:

\(\large\boxed{\bf\:x = \frac{73}{12} = 6\frac{1}{12} \approx 6.083}\)

Step-by-step explanation:

\(12(x - 7) = -11\)

Multiply 12 by x & 7 (distributive property) in the left hand side of the equation .

\(12(x-7)=-11\\(12*x)-(12*7)=-11\\12x - 84 =-11\)

Bring -84 to the right hand side of the equation. Then,

\(12x = -11 + 84\\12x = 73\\x=\frac{73}{12} \\\\\boxed{\bf\:x = \frac{73}{12} = 6\frac{1}{12} \approx 6.083}\)

Is the point (1,-4) a solution to the following system of equations? y=-4x y=x-5

Answers

Yes, the point (1, -4) is a solution to the given system of equations.

To determine if the point (1, -4) is a solution to the system of equations, we substitute the values of x and y into each equation and check if both equations are satisfied.

Given equations:

y = -4x    ... (1)

y = x - 5  ... (2)

Substituting x = 1 and y = -4 into equation (1):

-4 = -4(1)

-4 = -4

The equation is true when x = 1 and y = -4 in equation (1).

Substituting x = 1 and y = -4 into equation (2):

-4 = 1 - 5

-4 = -4

The equation is also true when x = 1 and y = -4 in equation (2).

Since both equations are satisfied when x = 1 and y = -4, the point (1, -4) is indeed a solution to the given system of equations.

Q1, also known as the first quartile or the 25th percentile, represents the value below which 25% of the data falls. It splits the lowest 25% of the dataset from the rest.

Q2, also known as the second quartile or the 50th percentile, is the median of the dataset. It represents the value below which 50% of the data falls, dividing the dataset into two equal parts.

Q3, also known as the third quartile or the 75th percentile, represents the value below which 75% of the data falls. It separates the highest 25% of the dataset from the rest.

These quartiles are useful in analyzing the distribution and dispersion of data, providing insights into the spread and central tendency.

They are commonly used in box plots, where the box represents the interquartile range (IQR), which is the range between Q1 and Q3, while the line inside the box represents the median (Q2).

Use the law of cosines to write an expression equivalent to b

Use the law of cosines to write an expression equivalent to b

Answers

Given:

A triangle ABC.

The given expression for b is:

\(b=\sqrt{m+n-pq}\)

To find:

The expression that is equivalent to b.

Solution:

According to the Law of Cosines,

\(b^2=a^2+c^2-2ac\cos B\)

It can be written as:

\(b=\sqrt{a^2+c^2-2ac\cos B}\)              ...(i)

We have,

\(b=\sqrt{m+n-pq}\)                                ...(ii)

On comparing (i) and (ii), we get

\(m=a^2\)

\(n=c^2\)

\(p=2ac\)

\(q=\cos B\)

Therefore, the required values are \(m=a^2,n=c^2,p=2ac,q=\cos B\).

the 3 conditions for sampling distributions must be met in order to calculate p-hat. group of answer choices true false

Answers

The correct answer is False because, If the sample size is large enough (n greater than or equal to 30) the sampling distribution is approximately normal regardless of the shape of the population.

The sample fraction, often called the "p-hat", is the ratio of the number of sample successes to the size of the sample. The standard deviation of (p) decreases as the sample size n increases. This is because n is included in the denominator of the standard deviation formula. That is, (p has) has fewer variables for larger samples. The P-hat (must be a lowercase p with a caret (^) circumflex) indicates the percentage of the sample (this is the x-bar, the average of the samples).

A p-hat (proportion) sampling distribution is a collection of equal-sized repeated sample proportions drawn from the same population to represent it. According to the central limit theorem, the sampling distribution of p-hat is approximately normally distributed for large sample sizes.

14. Supongamos que el 40 % de los votantes de una ciudad están a favor de la reelección del actual alcalde.


a) ¿Cuál es la probabilidad de que la proporción muestral de votantes en contra del alcalde sea menor al 50 %, en una muestra de 40 electores?

b) ¿Cuál es la proporción máxima de votantes a favor de la reelección que se podría observar en el 30 % de grupos de 50 votantes de menor aprobación hacia la reelección?

Answers

a) The probability of the sample proportion of voters against the mayor being less than 50% is 0.8461 or about 84.61%.

b) The maximum proportion of voters in favor of the reelection that would result in the lowest 30% of groups of 50 voters being against the reelection is 0.4097 or about 40.97%.

Using the normal approximation to the binomial distribution, we can find the probability of the sample proportion of voters against the mayor being less than 50% as follows:

First, we need to calculate the mean and standard deviation of the sampling distribution:

Mean (μ) = p = 0.4

Standard deviation (σ) = =√(p(1-p)/n) = √(0.4*0.6/40) = 0.09798

Next, we need to standardize the sample proportion using the formula z = (x - μ)/σ, where x is the sample proportion. We want to find the probability that z is less than (0.5 - 0.4)/0.09798 = 1.02. Using a standard normal distribution table or calculator, we find that the probability is approximately 0.8461.

for b), We want to find the maximum proportion of voters in favor of the reelection that would result in the lowest 30% of groups of 50 voters being against the reelection.

We can use the binomial distribution to find the probability that in a group of 50 voters, the number of voters against the reelection is greater than or equal to 25 (50% of the sample). We can then find the maximum proportion of voters in favor of reelection such that this probability is less than or equal to 0.3.

Using a binomial distribution calculator or formula, we find that the probability of 25 or more voters being against the reelection in a group of 50 voters is approximately 0.0747. We want this probability to be less than or equal to 0.3, so we need to find the maximum value of p such that P(X >= 25) <= 0.3.

Using a binomial distribution table or calculator, we can find that the maximum value of p is approximately 0.4097.
