The radius of a cylinder is reduced by 4% and it's height is increased by 2% then then volume of cylinder will reduced by 2 percent.

Assume that,

Radius of cylinder = r

Height of cylinder = h

Then volume of cylinder = π r² h

Now according to the given information,

radius is reduced by 4 percent,

Then,

r' = r - 0.04r

  = 0.96r

Height of cylinder is increased by 2%

Then,

h' = h + 0.02h

   = 1.02h

Therefore,

New volume of cylinder = π(0.96r)² (1.02h)

                                        = 0.940 π r² h

Now change of volume in percentage

=  [(0.940 π r² h -  π r² h)/π r² h]x100

= -0.06x100

= -6%

Hence volume of cylinder will reduced by 2 percent.

To verify whether the languages of two regular expressions r and s are equal, we can follow these steps:

Construct the finite automata for r and s.

Convert both the finite automata to their corresponding deterministic finite automata (DFA).

Minimize the DFAs obtained in step 2.

Compare the minimized DFAs to check if they are equivalent.

If the DFAs are equivalent, then the languages of r and s are also equal.

Alternatively, we can directly compare the regular expressions r and s by using the following algorithm:

Convert both r and s to their equivalent minimal deterministic finite automata (DFA).

Construct the product DFA of the two DFAs obtained in step 1.

Check if the accepting states of the product DFA correspond to the same regular expressions in r and s.

If the accepting states correspond to the same regular expressions, then l(r) = l(s). Otherwise, l(r) ≠ l(s).

Note that the above algorithm may not be efficient for larger regular expressions, and in such cases, constructing the minimal DFAs may be a more practical approach.

The correct formula for the homoskedasticity-only F-statistic is B. F = \((R^2_{unrestricted} - R^2_{restricted})/(q/(1 - R^2_{unrestricted}))/(n - k_{restricted} - 1).\)

The homoskedasticity-only F-statistic is used in regression analysis to test the equality of the error variances between two models, one unrestricted and one restricted. The formula for the F-statistic compares the goodness-of-fit between these two models.

The correct formula for the F-statistic is derived as follows: F = \((R^2_{unrestricted} - R^2_{restricted})/(q/(1 - R^2_{unrestricted}))/(n - k_{restricted} - 1)\),

where \(R^2_{unrestricted}\) is the coefficient of determination for the unrestricted model,

\(R^2_{restricted}\) is the coefficient of determination for the restricted model, q is the difference in the number of restrictions between the two models, n is the sample size,

and\(k_{restricted}\) is the number of parameters estimated in the restricted model.

Option B provides the correct formula for the homoskedasticity-only F-statistic, with the numerator representing the difference in \(R^2\) values and the denominator incorporating the necessary adjustments for degrees of freedom.

Therefore, the correct formula for the homoskedasticity-only F-statistic is B. F = \((R^2_{unrestricted} - R^2_{restricted})/(q/(1 - R^2_{unrestricted}))/(n - k_{restricted} - 1).\).

The strength of Altman's Z-score lies in its ability to provide a quantitative measure of a company's financial distress and bankruptcy risk. It condenses multiple financial ratios into a single score, making it easy to interpret and compare across different companies. The Z-score is a powerful tool for investors, creditors, and analysts as it can quickly identify companies that are at high risk of bankruptcy, allowing them to make informed decisions regarding investments, lending, and business partnerships. The Z-score has been widely tested and validated, showing significant predictive power in identifying bankruptcies.

Simple and Objective: Altman's Z-score provides a straightforward and objective assessment of a company's financial health. It combines several financial ratios that reflect different aspects of a company's financial condition into a single score, eliminating the need for subjective judgment or complex analysis.

Widely Accepted and Tested: Altman's Z-score has been extensively researched and tested, especially in predicting bankruptcies of publicly traded manufacturing companies. It has been found to be a reliable indicator of financial distress and has gained widespread acceptance in the financial industry.

Despite its strengths, Altman's Z-score has several limitations that should be considered:

Industry Specificity: Altman's Z-score was originally developed for manufacturing companies and may not be as accurate when applied to companies in other industries. Each industry has its own unique characteristics and risk factors that may require specific financial ratios or models for accurate prediction.

Limited Timeframe: The Z-score is designed to predict the likelihood of bankruptcy within a short-term period, typically one year. It may not provide a comprehensive assessment of a company's long-term financial stability or viability.

Economic and Market Factors: The Z-score assumes a stable economic environment and may not accurately predict bankruptcy during periods of economic downturns, industry disruptions, or market volatility. External factors that impact a company's financial health, such as changes in consumer preferences or technological advancements, are not explicitly considered.

Data Quality and Availability: The accuracy of the Z-score relies on the quality and availability of financial data. Inaccurate or manipulated financial statements can lead to misleading results. Additionally, if a company's financial data is not publicly available or is incomplete, the Z-score cannot be effectively applied.

Lack of Qualitative Factors: Altman's Z-score focuses solely on quantitative financial ratios and does not consider qualitative factors that can influence a company's financial health. Factors like management competence, competitive positioning, and industry trends are not incorporated into the Z-score model.

The maximum height the bullet will reach is 627 ft. The time(from the point when bullet was fired) it will take the bullet to hit the ground is 12.51 sec approx. The time when the bullet will be 403 ft above the ground are 2.475 sec and 10.02 sec approx.

To find the maximum of a continuous and twice differentiable function f(x), we can firstly differentiate it with respect to x and equating it to 0 will give us critical points.

Putting those values of x in the second rate of function, if results in negative output, then at that point, there is maxima. If the output is positive then its minima and if its 0, then we will have to find the third derivative (if it exists) and so on.

For this case, the height of the bullet from the ground is modeled by the equation:

\(h(t) = -16t^2 + 200t + 3\)

where height is in meters and time is in seconds. And t is the time in seconds passed from the point of time when the bullet was fired.

Finding its first and second rate with respect to the variable 't', we get:

\(\dfrac{d(h(t))}{dt} = h'(t) = -32t + 200\\\\\dfrac{d^2(h(t))}{dt^2} = h''(t) = -32 < 0\)

Thus, the second rate is negative no matter what the value of 't' is. So all the critical points would be corresponding to maxima.

Now, finding the critical points by equating the first rate = 0, we get:

\(h'(t) = 0\\\\-32t + 200 = 0\\\\t = \dfrac{200}{32} = 6.25 \: \rm sec.\)

Due to only one critical point, and that each critical point is maxima, we have the value of h(t) globally maximum when t = 6.25

Putting t = 6.25 in the function h(t), we get the maximum height achieved by the bullet as:

\(h(t) = -16t^2 + 200t + 3\\h(6.5) = -16(6.5)^2 + 200(6.5) + 3 = 627 \: \rm ft\)

When the bullet will fall on the ground, the value of h(t) would be 0.

Putting h(t) = 0, and finding the values of 't' for which this is true, we get:

\(h(t) = -16t^2 + 200t + 3\\0 = -16t^2 + 200t + 3\\\\16t^2 -200t -3 =0\\\\t = \dfrac{-(-200) \pm \sqrt{ (-200)^2 - 4(16)(-3)}}{2(16)}\\\\t \approx \dfrac{200 \pm 200.479}{32}\\\\t \approx -0.0149 \: \rm sec., t \approx 12.51 \: sec.\)

Bullet will fall only after it is shot, so time taken for the bullet to fall compared to the time when its shot would be greater, so time passed (t here) would be positive.

Thus, at approx t = 12.51 sec, the bullet will fall on the ground.

At  t = 0, bullet was at 3 ft, and therefore, whenever bullet will reach 400 ft, the time t would be > 0.

Putting h(t) = 400, we get:
\(h(t) = -16t^2 + 200t + 3\\400 = -16t^2 + 200t + 3\\\\16t^2 -200t +397 =0\\\\t = \dfrac{-(-200) \pm \sqrt{ (-200)^2 - 4(16)(397)}}{2(16)}\\\\t \approx \dfrac{200 \pm 120.797}{32}\\\\t \approx 2.475\: \rm sec., t \approx 10.02\: sec.\)

These both values are true. The time when t = 2.475 approx, the bullet would be going up, passing by 400 ft height, and when t = 10.02 approx, the bullet would be coming down, passing by 400 ft height.

Thus, the maximum height the bullet will reach is 627 ft. The time(from the point when bullet was fired) it will take the bullet to hit the ground is 12.51 sec approx. The time when the bullet will be 403 ft above the ground are 2.475 sec and 10.02 sec approx.

So your answer is

7295

I think that's the only one divisible by 5 but not 3.

===============

There's a quick way to divide by 3. Just add the digits. If the sum is divisible by 3 then the whole number is divisible by 3

For example 285

2 + 8 + 5 = 15.

15 is divisible by 3 so 285 is divisible by 3.

==================

7295 = 7 + 2 + 9 +5.  Anything adding up to 9 you can cast out.

7 + 2 = 9 Cast it out

9 = 9       Cast it out

5  is not divisible by 3, so 7295 is not divisible by 3

For a repeated measures ANOVA for n = 78, k = 7, SSb = 8, SSw = 8, SSerror = 71 , the value of Mean Square Error Term is  1  .

The Mean Squares Error Term (MSerror) is calculated by dividing the sum of squares error (SSerror) by the degrees of freedom for error (dfe), which is equal to (n - k). So , we have:

⇒ MSerror = (SSerror)/(dfe) ,

For n = 78 and k = 7 ,

We get ,

The degree of freedom for error (dfe) = 78 - 7 = 71 ,
