Statement of stockholders’ equity for CC for the year ended December 31, 2012:Particulars Amount ($)
Common Stock 100,000
Additional Paid-in Capital 4,100,000
Retained Earnings (Opening Balance) 3,000,000
Add: Net Income for the year ended December 31, 2012 800,000
Total retained earnings 3,800,000
Less: Cash Dividend Declared on July 1 and paid on July 31 (200,000)
Retained earnings (Closing balance) 3,600,000
Total stockholders’ equity 7,800,000
Explanation:The given information is as follows:Common Stock on January 1, 2012 = $100,000Additional Paid-in Capital on January 1, 2012 = $4,100,000
Retained Earnings on January 1, 2012 = $3,000,000Net Income for the year ended December 31, 2012 = $800,000Cash Dividend Declared on July 1 and paid on July 31 = $200,000
To prepare the statement of stockholders’ equity for the year ended December 31, 2012, we will begin by preparing the opening balances of each of the equity accounts. We will then add the net income to the retained earnings account.
The closing balance for retained earnings is then computed by subtracting the cash dividend declared and paid from the total retained earnings. Finally, the total stockholders' equity is calculated by adding the balances of all the equity accounts.
Calculations:Opening balance of common stock = $100,000
Opening balance of additional paid-in capital = $4,100,000
Opening balance of retained earnings = $3,000,000
Net Income for the year ended December 31, 2012 = $800,000
Retained earnings (Opening Balance) = $3,000,000
Add: Net Income for the year ended December 31, 2012 = $800,000
Total retained earnings = $3,800,000Less: Cash Dividend Declared on July 1 and paid on July 31 = $200,000Retained earnings (Closing balance) = $3,600,000
Total stockholders’ equity = Common Stock + Additional Paid-in Capital + Retained Earnings (Closing balance) = $100,000 + $4,100,000 + $3,600,000 = $7,800,000
Therefore, the statement of stockholders’ equity for CC for the year ended December 31, 2012, is as follows:Particulars Amount ($)

1. (35 points) Solve the following differential equations with or without the given initial conditions. (d) y' = -Vt+1 7+ vt +1 (e) y' - y = t?, y(0) = 1 = =
The general equation to the differential equation
(d) y' = -Vt + 17 + vt + 1 is y = ((v - V)/2)t² + 18t + C, where V and v are constants.
(e) y' - y = t, where y(0) = 1 is \(y = -t - 1 + 2e^{t}\).
(d) To solve the differential equation y' = -Vt + 17 + vt + 1, we can separate the variables and integrate.
Separating variables:
dy = (-Vt + 17 + vt + 1) dt
Integrating both sides:
∫ dy = ∫ (-Vt + 17 + vt + 1) dt
Integrating each term:
y = (-V/2)t² + 17t + (v/2)t² + t + C
Combining like terms:
y = (-V/2 + v/2)t² + 17t + t + C
Simplifying:
y = ((v - V)/2)t² + 18t + C
So the general solution to the differential equation is y = ((v - V)/2)t² + 18t + C, where V and v are constants.
(e) To solve the differential equation y' - y = t, where y(0) = 1, we can use an integrating factor.
The differential equation can be written as:
y' - y = t
The integrating factor is given by the exponential of the integral of the coefficient of y, which in this case is -1:
\(IF = e^{(-\int1 dt)} = e^{(-t)}\)
Multiplying the equation by the integrating factor:
\(e^{(-t)}(y' - y) = e^{(-t)}(t)\)
Applying the product rule on the left side:
\((e^{(-t)}y)' = e^{(-t)}(t)\)
Integrating both sides:
\(\int(e^{-t}y)' dt = \int e^{-t}(t) dt\)
Integrating each side:
\(e^{-t}y = -e^{-t}t - e^{-t} + C\)
Simplifying:
\(y = -t - 1 + Ce^{t}\)
Using the initial condition y(0) = 1:
1 = -0 - 1 + Ce⁰
1 = -1 + C
Solving for C:
C = 2
Therefore, the solution to the differential equation with the given initial condition is:

Compute the correlation coefficient for the following data set x| 1 2 3 4 5 6 7 y| 2 1 4 3 7 5 6 Also, compute the correlation coefficient for this data set x| 1 2 3 4 5 6 7 y| 5 4 7 6 10 8 9 Is the result the same or different for both (a) and (b)? Explain w in your answer is the same, or different, as the case may be.
Correlation coefficient is a measure that assesses the linear correlation between two variables in a data set. Correlation coefficient is a dimensionless value that ranges from -1 to +1. A correlation coefficient of -1 shows a perfect negative correlation, while a correlation coefficient of +1 shows a perfect positive correlation.
A correlation coefficient of 0 shows no correlation between the variables. Here's how to compute the correlation coefficient for the given data set:a) x| 1 2 3 4 5 6 7 y| 2 1 4 3 7 5 6Let's first compute the means of x and y, and then we can compute the correlation coefficient:mean of x = (1+2+3+4+5+6+7)/7 = 4mean of y = (2+1+4+3+7+5+6)/7 = 4Now, we can use the formula for the correlation coefficient:
\(r = [(1-4)*(2-4) + (2-4)*(1-4) + (3-4)*(4-4) + (4-4)*(3-4) + (5-4)*(7-4) + (6-4)*(5-4) + (7-4)*(6-4)] / [(1-4)^2 + (2-4)^2 + (3-4)^2 + (4-4)^2 + (5-4)^2 + (6-4)^2 + (7-4)^2] = -0.02\)
So, the correlation coefficient for this data set is -0.02.b) x| 1 2 3 4 5 6 7 y| 5 4 7 6 10 8 9Again, let's compute the means of x and y:mean of x = (1+2+3+4+5+6+7)/7 = 4mean of y = (5+4+7+6+10+8+9)/7 = 7We can use the formula for the correlation coefficient:
\(r = [(1-4)*(5-7) + (2-4)*(4-7) + (3-4)*(7-7) + (4-4)*(6-7) + (5-4)*(10-7) + (6-4)*(8-7) + (7-4)*(9-7)] / [(1-4)^2 + (2-4)^2 + (3-4)^2 + (4-4)^2 + (5-4)^2 + (6-4)^2 + (7-4)^2] = 0.82\)
So, the correlation coefficient for this data set is 0.82.The result is different for both (a) and (b). The correlation coefficient for data set (a) is -0.02, which indicates almost no correlation, while the correlation coefficient for data set (b) is 0.82, which indicates a strong positive correlation.

A binomial experiment with probability of success p=0.63 and n=11 trials is conducted. What is the probability that the experiment results in 10 or more successes? Do not round your intermediate computations, and round your answer to three decimal places (if necessary consulta list of formes.)
To find the probability of getting 10 or more successes in a binomial experiment with p = 0.63 and n = 11 trials, we can use the cumulative probability function.
P(X ≥ 10) = 1 - P(X < 10)
Using a binomial probability formula, we can calculate the probability of getting exactly k successes:
P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)
where C(n, k) represents the binomial coefficient.
Let's calculate the probability for each value from 0 to 9 and subtract it from 1 to get the probability of 10 or more successes:
P(X < 10) = P(X = 0) + P(X = 1) + P(X = 2) + ... + P(X = 9)
P(X < 10) = Σ[C(11, k) * p^k * (1 - p)^(11 - k)] for k = 0 to 9
Using this formula, we can calculate the probability:
P(X < 10) ≈ 0.121
Therefore, the probability of getting 10 or more successes in the binomial experiment is:
P(X ≥ 10) ≈ 1 - P(X < 10) ≈ 1 - 0.121 ≈ 0.879
Rounding to three decimal places, the probability is approximately 0.879.

2. What is the composition of two functions, f ∘ g ?
In summary, the composition of two functions, f ∘ g, combines the outputs of the function g as inputs to the function f.
The composition of two functions, f ∘ g, is a new function that is formed by applying the output of the function g as the input of the function f.
To find the composition of f ∘ g, follow these steps:
1. Start with the function g(x) and evaluate it for a given input value, let's call it 'a'. This will give you g(a).
2. Take the output g(a) and use it as the input for the function f(x). Evaluate f(x) with this input value to get f(g(a)).
3. The final result f(g(a)) is the value of the composition of the two functions f ∘ g at the input 'a'.
In terms of composition notation, f ∘ g is read as "f composed with g" or "f of g". It represents the order in which the functions are applied: g is applied first, and then f is applied to the result of g.

if an organization wants to test whether a minority of its employees are dissatisfied with their bonus, the alternative hypothesis would be that the true population proportion would be:
Answer: If an organization wants to test whether a minority of its employees are dissatisfied with their bonus, the alternative hypothesis would be that the true population proportion is greater than the null hypothesis proportion.
Specifically, the null hypothesis would be that the proportion of employees who are dissatisfied with their bonus is equal to or less than a certain value (usually 0.5 or 0.1, depending on the context). The alternative hypothesis would be that the proportion of employees who are dissatisfied with their bonus is greater than this value.
For example, if the null hypothesis is that 20% of employees are dissatisfied with their bonus, the alternative hypothesis would be that more than 20% of employees are dissatisfied with their bonus.
The alternative hypothesis is typically the hypothesis of interest, as it represents the hypothesis that the organization wants to investigate and potentially take action on.
Step-by-step explanation:
The alternative hypothesis would be that the true population proportion of dissatisfied employees regarding their bonus is greater than the assumed proportion.
The null hypothesis assumes that the proportion of dissatisfied employees regarding their bonus is equal to the assumed proportion. The alternative hypothesis, in contrast, assumes that the proportion of dissatisfied employees is greater than the assumed proportion. In this case, the organization wants to test whether a minority of its employees are dissatisfied with their bonus, which implies that the assumed proportion is less than 50%. Therefore, the alternative hypothesis states that the true population proportion of dissatisfied employees regarding their bonus is greater than the assumed proportion. By conducting hypothesis testing, the organization can determine whether the evidence supports the null hypothesis or the alternative hypothesis and make decisions accordingly.

in a circle, a sector with central angle is 225 degrees intercepts an arc of length 30pi in. find the diameter of the circle
The diameter of the circle is approximately 60 inches.
To explain further, we can use the formula relating the central angle of a sector to the length of its intercepted arc. The formula states that the length of the intercepted arc (A) is equal to the radius (r) multiplied by the central angle (θ) in radians.
In this case, we are given the central angle (225 degrees) and the length of the intercepted arc (30π inches).
To find the diameter (d) of the circle, we need to find the radius (r) first. Since the length of the intercepted arc is equal to the radius multiplied by the central angle, we can set up the equation 30π = r * (225π/180). Simplifying this equation gives us r = 20 inches.
The diameter of the circle is twice the radius, so the diameter is equal to 2 * 20 inches, which is 40 inches. Therefore, the diameter of the circle is approximately 60 inches.
In summary, by using the formula for the relationship between central angle and intercepted arc length, we can determine the radius of the circle. Doubling the radius gives us the diameter, which is approximately 60 inches.

what effect does increasing the sample size have on the probability? provide an explanation for this result.
Increasing the given sample size will decreases the probability because σx will decreases as n value increases.
In Statistitics whenever we test a hypothesis for testing a statistic, we use confidence interval. Confidence interval is on either side of an assumed value a margin of error. Margin of error is calculated as critical value * sigma/sqrt of n. Thus we find that whenever n increases, margin of error decreases.
Thus making confidence interval narrower and thus making probability for accepting null hypothesis a less value. As the pattern sizes increase, the range of every sampling distribution decreases so they emerge as more and more leptokurtic. The variety of the sampling distribution is smaller than the variety of the authentic populace. Therefore, as a pattern length increases, the pattern imply and general deviation might be nearer in fee to the populace imply μ and general deviation σ.

For a Scalar function , Prove that X. ( =0)
(b) When X1 ,X2 ,X3 are
linearly independent solutions of X'=AX, prrove that
2X1-X2+3X3 is also a solution of
X'=AX
To prove that X(=0), we need to show that when X is a scalar function, its derivative with respect to time is zero.
Let's consider a scalar function X(t). The derivative of X(t) with respect to time is denoted as dX/dt. To prove that X(=0), we need to show that dX/dt = 0.
The derivative of a scalar function X(t) is computed as dX/dt = AX(t), where A is a constant matrix and X(t) is a vector function.
Since X(=0), the derivative becomes dX/dt = A(0) = 0. Thus, the derivative of X(t) is zero, which proves that X(=0).
Now, let's consider the second part of the question. We are given that X1, X2, and X3 are linearly independent solutions of the differential equation X'=AX. We need to prove that 2X1-X2+3X3 is also a solution of the same differential equation.
We can verify this by substituting 2X1-X2+3X3 into the differential equation and checking if it satisfies the equation.
Taking the derivative of 2X1-X2+3X3 with respect to time, we get:
d/dt (2X1-X2+3X3) = 2(dX1/dt) - (dX2/dt) + 3(dX3/dt)
Since X1, X2, and X3 are linearly independent solutions, we know that dX1/dt = AX1, dX2/dt = AX2, and dX3/dt = AX3.
Substituting these expressions, we get:
2(dX1/dt) - (dX2/dt) + 3(dX3/dt) = 2(AX1) - (AX2) + 3(AX3)
Using the properties of matrix multiplication, this simplifies to:
A(2X1-X2+3X3)
Thus, we can conclude that 2X1-X2+3X3 is also a solution of the differential equation X'=AX.
The proof shows that for a scalar function X(=0), the derivative is zero. Additionally, for the given linearly independent solutions X1, X2, and X3, the expression 2X1-X2+3X3 is also a solution of the differential equation X'=AX.

elsa is designing a commercial jet. she drew a model of her design using the scale shown below. According to her design what will be the length and width in feet of the actual jet
Answer:
55
Step-by-step explanation:
mountain climbing: accidents the following problem is based on information taken from accidents in north american mountaineering (jointly published by the american alpine club and the alpine club of canada). let x represent the number of mountain climbers killed each year. the long-term variance of x is approximately s2 5 136.2. suppose that for the past 8 years, the variance has been s2 5 115.1. use a 1% level of significance to test the claim that the recent variance for number of mountain climber deaths is less than 136.2. find a 90% confidence interval for the population variance.
The test statistic (6.01) is lesser than the critical value (2.167), we reject the null thesis. Therefore, there's sufficient substantiation to support the claim that the recent friction for the number of mountain rambler deaths is lower than 136.2.
To find a 90 confidence interval for the population friction, we can use the ki-square distribution with 7 degrees of freedom. thus, we can say with 90 confidence that the population friction lies within the interval(3.325,14.067).
To test the claim that the recent friction for the number of mountain rambler deaths is lower than136.2, we can conduct a one- tagged thesis test using the ki-square distribution. The null and indispensable suppositions are as follows Null thesis( H ₀) The recent friction is equal to or lesser than136.2( σ ² ≥136.2).
Indispensable thesis( H ₁) The recent friction is lower than136.2( σ ²<136.2).
Using the given information, we can calculate the test statistic as Test Statistic =
(( n- 1) * s ²) σ ²
where n is the sample size( 8) and s ² is the recent friction(115.1). Calculating the test statistic yields Test Statistic
= (( 8- 1) *115.1)/136.2 ≈6.01
With a significance position of 1 and 7 degrees of freedom( n- 1), the critical ki-square value is roughly2.167.
