In a Stock Dividend Assets don't change, Liabilities don't change.

In a stock dividend scenario, where a company issues additional shares of its own stock to existing shareholders, the impact on the company's balance sheet is as follows:

Assets don't change, Liabilities don't change.

When a company declares a stock dividend, it is essentially distributing a portion of its retained earnings or accumulated profits to its shareholders in the form of additional shares. This means that the company is not receiving any new assets or incurring any new liabilities in the process.

From an accounting perspective, the value of the stock dividend is reflected in the equity section of the balance sheet. The retained earnings account decreases by the value of the dividend, while the common stock or additional paid-in capital account increases by the same value. This adjustment does not affect the company's assets or liabilities.

Therefore, the correct answer is: Assets don't change, Liabilities don't change.

Answer:

Please refer to the attached image for a possible graph of given equation.

Step-by-step explanation:

Given the equation:

\(g(x) = x^2 + d\)

Let us write the equation as:

\(y = x^2 + d\) so that we can plot it on xy axis.

The highest power of x is 2.

The given equation resembles with the equation of a parabola.

The vertex form of a parabola is given as:

\(y = a(x - h)^2 + k\)

Here (h,k) is the vertex of parabola.

Vertex of the parabola is the point on the axis of symmetry and is the highest or the lowest point on parabola.

Now, let us compare the given equation of parabola with the standard vertex form of parabola. We get the following values:

a = 1 > 0 hence, parabola will open upwards.

h = 0

k = d

So, the vertex is at O (0,d). It means vertex will be on the y axis.

Now, we are given that d < 0 that means the vertex will be on negative y axis.

Now, let us suppose d = -8, the graph will be as attached in the answer area. Please have a look.

Answer:

X and y answer is 45 degrees

Answer:

x = 20, y = 70 degrees.

Step-by-step explanation:

x + y = 90 degrees  ( As the large triangle is right-angled).

Now x is the base angle of an isosceles triangle so the small angle that is part of the right angle = x. Call this angle z.

Consider the small triangle which includes 40 degrees:

y + 40 + 90 - z = 180     But as  z = x:

y + 130 - x = 180

y - x = 50

Adding the equation to the highlighted equation above we have:

2y = 90 + 50

2y = 140

y = 70 degrees.

So x + 70 = 90

giving x = 20 degrees.

Answer: See explanation

Step-by-step explanation:

x=-(2-2*the square root of 6)/5, about 0.58

or

x=-(2+2*the square root of 6)/5, about -1.38

The values of the x from equation  \(5x^2+4x-4=0\) are  x = 0.5798 and -1.38.

Given that:

Equation:  \(5x^2+4x-4=0\)

To find the values of x that satisfy the equation \(5x^2+4x-4=0\), use the quadratic formula:

\(x = \dfrac{ -b \± \sqrt{b^2 - 4ac}}{ 2a}\)

Compare the equation with \(ax^2 + bx + c = 0\).

Here, a = 5, b = 4, and c = -4.

Plugging in the values to get,

\(x = \dfrac{-4 \± \sqrt{4^2 - 4 \times 5 \times (-4)}}{2 \times 5} \\x = \dfrac{-4 \± \sqrt{16 +80}}{10} \\x = \dfrac{-4 \± \sqrt{96}}{10}\\x = \dfrac{-4 \± {4\sqrt6}}{10}\)

So the solutions for x are calculates as:

Taking positive sign,

\(x = \dfrac{-4 + {4\sqrt6}}{10}\\x = \dfrac{-4 + {9.798}}{10}\\\)

x = 5.798/10

x = 0.5798

Taking negative sign,

\(x = \dfrac{-4 - {4\sqrt6}}{10}\\x = \dfrac{-4 - {9.798}}{10}\\\)

x = -13.798/10

x = -1.38

Hence, the exact solutions for the equation  \(5x^2 + 4x - 4 = 0\)  are x = 0.5798 and -1.38.

Answer:

minutes took to finish the race = 54 minutes

Step-by-step explanation:

It's known that:

\(speed = \frac{distance}{time}\)

then:

\(time = \frac{distance}{speed}\)

IN THE 1ST 10 MILES:

time = \(\frac{10}{25} = \frac{2}{5} = 0.4 hours\)

IN THE 2ST 10 MILES:

time = \(\frac{10}{20} = 0.5 hours\)

Hence, Overall time took to finish the race = 0.4 + 0.5 = 0.9 hours

time in minutes = 0.9 × 60 = 54 minutes


Another Solution:

Overall speed = \(\frac{S_1 + S_2}{2}\), Where: S1: 1st speed, S2: 2nd speed

then:

speed = \(\frac{25 + 20}{2}= 22.5 mph\)

Hence, time took = \(\frac{20}{22.5} = 0.9 hours = 54 minutes\)

Answer:

If y is inversely proportional to the cube root of x, we can write the equation:

y = k / (x^(1/3))

where k is a constant of proportionality. To find k, we can use the given information that x=64 when y=12.75:

12.75 = k / (64^(1/3))

Simplifying:

12.75 = k / 4

k = 51

So the equation connecting x and y is:

y = 51 / (x^(1/3))

To find the value of x when y=3, we can plug in y=3 into the equation we just found and solve for x:

3 = 51 / (x^(1/3))

Simplifying:

x^(1/3) = 51 / 3

x^(1/3) = 17

Cubing both sides:

x = 17^3

x = 4913

So when y=3, x=4913.

If we divide x by 125, we can write the new value of x as x/125. To find the new value of y, we can plug this into the equation we found in part 1:

y = 51 / ((x/125)^(1/3))

Simplifying:

y = 51 / ((1/125)^(1/3)) * (x^(1/3))

y = 51 / 5 * (x^(1/3))

So the new value of y is:

y' = 51 / 5 * ((x/125)^(1/3))

To find the change in y, we can subtract the original value of y from the new value:

Δy = y' - y

Δy = 51 / 5 * ((x/125)^(1/3)) - 51 / (x^(1/3))

Simplifying:

Δy = 51 / 5 * ((x/125)^(1/3)) - 51 * (x^(-1/3))

Note that we can simplify this expression further by finding a common denominator, but this is the final answer.

Step-by-step explanation:

The number of elements in the sample space for this experiment is 969.

If a person eating at a cafeteria must choose 3 of 19 vegetables on offer, we can calculate the number of elements in the sample space, or the total number of possible outcomes, using the formula for combinations:

nCr = n! / [r!(n - r)!]

where n is the total number of items in the set and r is the number of items being chosen.

In this case, we have 19 vegetables and we want to choose 3 of them, so we can plug in n = 19 and r = 3:

19C3 = 19! / [3!(19 - 3)!]

= 19! / (3!)(16!)

= 969

Therefore, there are 969 possible combinations of 3 vegetables that a person can choose from a selection of 19 vegetables.

y = x² - 5x - 6- - - - - - - - - - - - (1)

y = 2x - 6- - - - - - - - - - - (2)

We would apply the method of substitution by substituting equation 2 into equation 1. It becomes

x² - 5x - 6 = 2x - 6

x² - 5x - 6 = 2x - 6

x² - 7x = 0

x(x - 7) = 0

x = 0 or x - 7 = 0

x = 7 or x = 0

Substituting x = 0 into equation 2, it becomes

Answer:

21.7 m

Step-by-step explanation:

The question above is a right angle triangle and we would be using the trigonometric function of tangent to solve for it.

tan θ = Opposite/ Adjacent

Opposite side = Height = unknown

Adjacent = 20sqrt(3) m

θ = Angle of Elevation = 30°

Hence, we have:

tan 30° = Opposite/ 20√3

Opposite = tan 30° × 20√3m

Opposite = 20m

Height of the tower = Height of the observer + Height (Opposite side)

Height = 20m

Height of the the observer as given in the question is = 1.7m

Height of the tower = 20m + 1.7m

= 21.7m

Therefore, the height of the tower = 21.7m

The mean of the given fuel prices data set is $4.61 with a standard deviation of $1.62.

To calculate the mean and standard deviation in Excel, you can use the following functions:

Mean: The AVERAGE function calculates the mean of a range of values. In this case, enter "=AVERAGE(A1:A30)" in an Excel cell, assuming the data is in cells A1 to A30.

Standard Deviation: The STDEV.S function calculates the standard deviation of a range of values. Enter "=STDEV.S(A1:A30)" in an Excel cell to calculate the standard deviation of the data set.

Using the mean ($4.61) and standard deviation ($1.62), we can now proceed to calculate the Confidence Interval.

The Confidence Interval can be determined using the formula: E = Z * (σ / √n)

In the formula, Z is the z-score corresponding to the desired level of confidence (e.g., 95% confidence corresponds to a z-score of approximately 1.96), σ is the population standard deviation (which can be estimated using the sample standard deviation in this case), and n is the sample size.

Let's assume we want a 95% confidence interval for the data set with a sample size of 30. We can use the formula "=CONFIDENCE.NORM(0.05, STDEV, 30)" in an Excel cell to calculate the E value.

Substituting the values into the formula, we get E = 1.96 * (1.62 / √30) ≈ 0.595.

Now, we can set up the confidence interval using the mean and E value:

Confidence Interval = (mean - E, mean + E)

Confidence Interval = ($4.61 - $0.595, $4.61 + $0.595)

Confidence Interval = ($4.015, $5.205)

Therefore, the 95% Confidence Interval for the given fuel prices data set is approximately $4.015 to $5.205.

In summary, the mean of the fuel prices data set is $4.61 with a standard deviation of $1.62. The 95% Confidence Interval for the data is approximately $4.015 to $5.205.
