A picture frame is shaped like a rectangle whose perimeter is 140 cm. The length is 4 times as long as the width. Find the length and the width.​

Answers

Answer 1

Answer:

L= 56cm

W= 14cm

Step-by-step explanation:

Given data

Perimeter of the frame= 140cm

Let the width be

W=x cm

Length= 4x

We know that

P= 2L+2W

subsitute

140= 2(4x)+2(x)

140 = 8x+2x

140= 10x

Divide both sides by 10

x= 140/10

x= 14cm

The length is

L= 4(14)

L= 56cm

Study the information provided below and answer the questions that follow. Chief executive officers (CEOs) have long been a focus of organisational research. This emphasis is understandable, given the widespread belief that a firm's top executive has a substantial impact on its performance. Three years ago, the board of directors (BOD) of TMG Ltd and the then incumbent CEO mutually agreed to part ways due to poor financial performance of the business. The new CEO appointed to replace him was mandated by the BOD to initiate an intervention strategy to turn around the business. As part of a review of the financial performance of the business, a researcher has recently been contracted by the BOD of TMG Ltd to determine whether the intervention strategy introduced three years ago by the current CEO has produced significantly improved outcomes for the business. The BOD wants the quarterly operating profit margin of the business for the past six year to constitute the unit of analysis. Table 4.1, below, shows the quarterly operating profit margin retrieved from the database of the company. Table 4.1: Quarterly operating profit margin (%) of TMG Ltd over the past six years.

Answers

The quarterly operating profit margin of TMG Ltd over the past six years is provided in Table 4.1, indicating the financial performance of the business during that period.

In order to assess the impact of the intervention strategy introduced by the current CEO three years ago, the board of directors (BOD) of TMG Ltd has contracted a researcher to analyze the data and determine if there have been significant improvements in the business outcomes. The quarterly operating profit margin serves as the unit of analysis for this evaluation.

Table 4.1 allows the researcher to examine the trend and fluctuations in the quarterly operating profit margin over the six-year period. By analyzing the data, the researcher can identify any noticeable changes in the financial performance of TMG Ltd, particularly after the implementation of the intervention strategy. The BOD is interested in understanding whether the strategy has resulted in improved profitability and overall financial health of the company.

The researcher will likely perform statistical analysis, such as calculating averages, trends, and identifying any significant variations, to draw conclusions about the effectiveness of the intervention strategy. By comparing the quarterly operating profit margin before and after the strategy's implementation, the researcher can assess whether the new CEO's efforts have had a positive impact on the company's financial performance.

Answers

For a taxable income of $1,80,900, the effective tax rate is 21.11%.

what is meant by marginal tax?

Marginal tax is the tax rate applied to an individual’s last dollar of income. It is the additional tax that must be paid on any additional income earned. In other words, it is the tax rate that applies to an individual’s income after all deductions. For example, if an individual’s income is $50,000 and the marginal tax rate is 25%, then the individual must pay an additional $12,500 in taxes on top of the $25,000 in taxes already paid on their $50,000 income.

Marginal tax rates are progressive, meaning that as an individual’s income increases, the marginal tax rate will increase as well. The marginal tax rate is important to understand because it helps individuals determine how much additional income they will need to earn in order to make up for the taxes they will have to pay on that income. It is also important to understand how marginal tax rates can affect tax planning strategies.

To determine the effective tax rate for a taxable income of $180,900, calculate the sum of the marginal tax rates for each tax bracket that the $180,900 falls into. The taxable income of $180,900 is greater than $89,075 and less than $170,050. The marginal tax rates for these two tax brackets are 22% and 24%, respectively. The sum of the marginal tax rates is 46%. Divide the sum by the taxable income of $180,900 to get the effective tax rate of 21.11%. Round the final answer to the nearest hundredth to get 21.11%.

Convert 71 kg to lbs

Answers

71 kg is equal to 156.53 pounds.

To convert kilograms (kg) to pounds (lbs), you can use the conversion factor 1 kg = 2.205 lbs. To convert 71 kg to lbs, you would multiply 71 by 2.205, which gives you 156.53 pounds.

It's important to note that the pound is a unit of weight in the Imperial system of measurement, while the kilogram is a unit of weight in the Metric system of measurement. These two systems are not directly comparable, so it's essential to use a conversion factor when switching between them.

In addition, it's good to know that the pound is commonly used in the United States, while the kilogram is more commonly used in other countries around the world.

It's worth mentioning that the conversion factor is exact, but due to rounding errors when converting large numbers of kilograms to pounds, there might be a slight discrepancy in the result.

Answers

Answer:

1. 4

2. rise = 2; run = 1; slope = 2

3. y = 2x + 4

Step-by-step explanation:

1. Look at the graph. On the y-axis, the line passes through 4. The line crosses the y-axis at 4, so 4 is the y-intercept, and b = 4 in the equation y = mx + b.

2. Choose any two points on the line. I choose the y-intercept, (0, 4) and point (-1, 2).

slope = rise/run

We need to go from point (-1, 2) to point (0, 4) by only moving vertically and horizontally. Start at (-1, 2). Go up 2 units. That is a ris of 2. Now go right 1 unit to arrive at point (0, 4). that is a run of 1.

slope = rise/run = 2

3. We have b = 4, and m = 2.

y = mx + b

y = 2x + 4

Answers

A. Main Answer:

The hypothesis that the variability in both populations is the same against the alternative that it is larger in the second population, we can perform a permutation test using two different test statistics:

(i) the difference of sample ranges and

(ii) the ratio of sample variances. By comparing the results of both test statistics, we can draw conclusions about the variability in the populations.

(i) Difference of Sample Ranges:

1. Calculate the sample range for each sample. The sample range is the difference between the maximum and minimum values in the sample.

  Sample 1 Range = Maximum value - Minimum value for Sample 1

  Sample 2 Range = Maximum value - Minimum value for Sample 2

2. Calculate the observed difference of sample ranges, which is the difference between the sample range of Sample 2 and Sample 1.

3. Pool the data from both samples and shuffle them randomly, keeping the same sample sizes.

4. Calculate the difference of sample ranges for the shuffled data.

5. Repeat steps 3 and 4 many times (e.g., 1000 permutations) to obtain a distribution of the difference of sample ranges under the null hypothesis (where variability is the same in both populations).

6. Compare the observed difference of sample ranges from step 2 with the distribution obtained from the permutations.

(ii) Ratio of Sample Variances:

1. Calculate the sample variance for each sample.

2. Calculate the observed ratio of sample variances, which is the ratio of the sample variance of Sample 2 to the sample variance of Sample 1.

3. Pool the data from both samples and shuffle them randomly, keeping the same sample sizes.

4. Calculate the ratio of sample variances for the shuffled data.

5. Repeat steps 3 and 4 many times (e.g., 1000 permutations) to obtain a distribution of the ratio of sample variances under the null hypothesis.

6. Compare the observed ratio of sample variances from step 2 with the distribution obtained from the permutations.

By comparing the results of both test statistics, we can assess whether the variability in the second population is significantly larger than the first population. If both test statistics consistently indicate larger variability in the second population, it provides evidence against the null hypothesis and suggests that the variability in the second population is indeed larger.

Answers

Answer:

The initial value of the boat was $20,000

The percent decrease per year of the value of the boat is 10%.

The interval on which the value of the boat is decreasing while Harry has it is (0,10)

Step-by-step explanation:

It is given that the boat costs $20,000 in 2010 when x = 0. So, the initial value of the boat was $20,000.

Next, find the percent decrease per year of the value of the boat. Consider the general form of an exponential equation, y = a(b)x, where a is the initial value of the boat, b is the base of the exponent, x is the number of years after 2010, and y is the value of the boat, in dollars.

Consider the point (1 , 18,000) which lies on the graph of this situation. Substitute x = 1, y = 18,000, and a = 20,000 into the exponential equation and isolate b.

Recall that for exponential decay, b = 1 - r where r represents the decay rate. Substitute b = 0.9 into this equation and solve for r.

So, the decay rate is 0.1, and the percent decrease per year of the value of the boat is 10%.

Harry bought the boat in 2010, and plans on selling it after 10 years in 2020. Therefore, the interval on which the value of the boat is decreasing while Harry has it is [0, 10].

(a) Assume the price of product from company A is p and the quantity of product from company A is qa Due to the supply-demand relationship, p is proportional to -₁ and can be expressed as p = -kq₁ + Po. The cost of each product is c. Let ya be the profit of company A. How many should company A produce to realize the maximal profit? (5 points) (b) Assume there's also company B in the market. The price of product from company B is also p and the quantity of product from company B is qB. Now the price is determined by the total quantity: p = -k(9A + 9B) + Po. The cost of each product is also c. Given the quantity of product from company B is x, how many should company A produce to realize the maximal profit? (10 points) (c) If both company A and B want to realize their maximal profit, what is the price of the product would be?

Answers

(a) Therefore, the company A should produce (Po - c) / (2k) to achieve maximum profit.

(b) Company A should produce

qA = (Po - c - kx) / (2k) - x/2

to maximize its profit.

(c) The price of the product would be; P = 10c - 10k (qA + qB)

(a) It can be expressed that the cost of each product is c. Let ya be the profit of company A.

Let's find the profit function of company A as follows;

Profit function of company A,

ya = pqa - cqa

= (Po - kqA)qA - cqA

= (Po - kqA)qA - c(qA)

Simplifying it by taking the first-order derivative,

ya = Po - 2k

qA - c = 0 or qA = (Po - c) / (2k)

Therefore, the company A should produce (Po - c) / (2k) to achieve maximum profit.

(b) Given that the quantity of product from company B is x.

Let's find the profit function of company A as follows;Profit function of company A,

ya = pqa - cqa

= (Po - k(qA + qB))(qA + qB) - c(qA)

where, qB = x

Let's calculate the partial derivative of this equation w.r.t qA and equate it to 0 and then find qA, the optimal quantity of A that maximizes its profit.

Then, ya = (Po - k(qA + x))(qA + x) - cqA

Then,

dy/dqA = -k(qA + x) + Po - 2kqA - c

= 0 or qA

= (Po - c - kx) / (2k) - x/2

Therefore, company A should produce

qA = (Po - c - kx) / (2k) - x/2

to maximize its profit.

(c) By substituting qA and qB in the equation

p = -k(9A + 9B) + Po

we get;

p = -k(9(Po - c - kx) / (2k) - 9x/2 + 9(Po - c - kqA) / (2k)) + Po

= -9(Po - c + k(x + qA)) + Po

Therefore, the price of the product would be; P = 10c - 10k (qA + qB)

Answers

There are 6 pairs of strings that have at least 6 beads.We have to evaluate 35*17 - 15*7

Given expression: 35*17-15*7= 595-105= 490Thus, the required value is 490.There are 16 pairs of two strings of beads that can be formed if you want each string to have at least 6 beads. We have 18 beads, so when the necklace is divided into two, the minimum number of beads on each string is six.To count the number of ways we can do this, we should first count the total number of ways the necklace can be split into two parts. We know that the order in which the strings are arranged does not matter, so we can divide by 2 to account for this.We can divide the necklace at any point, resulting in 18 possible locations.

This gives us a total of 18/2=9 ways to split the necklace.Next, we'll figure out how many of these possibilities result in at least one string with fewer than 6 beads. This can only happen if we cut the necklace at one of the three positions closest to either end (positions 1, 2, or 3, or positions 16, 17, or 18). The other six cuts (positions 4 through 9) result in each string having at least 6 beads.Instead of counting the number of ways we can get at least one short string, we'll count the number of ways we can avoid getting one. This means we'll count the number of ways both strings can have 6 or more beads. There are 6 possible positions for each string, for a total of 6x6=36 ways to pick two strings with at least 6 beads. Out of the total 9 possible cuts, 3 of them result in at least one string with fewer than 6 beads. So, the number of possible pairs of strings with at least 6 beads is:9 - 3 = 6Therefore, there are 6 pairs of strings that have at least 6 beads.

Binita is going to buy 450 envolopes

Answers

Buying from Value World would cost Binita £0.72 less (in pounds) than buying from Letters2go.

To compare the costs of envelopes from both shops, we need to calculate the price per envelope.

At Letters2go, the price per envelope is:

3.29 pounds / 25 envelopes = 0.1316 pounds per envelope

At Value World, the price per envelope is:

(1.95 pounds * 2 packs) / (10 envelopes * 2 packs + 1 free pack) = 0.1300 pounds per envelope

So the price per envelope at Value World is slightly less than the price per envelope at Letters2go.

To buy 450 envelopes, Binita would need to purchase:

18 packs of 25 envelopes at Letters2go (18 x 25 = 450 envelopes)

45 packs of 10 envelopes at Value World (45 x 10 = 450 envelopes)

At Letters2go, the cost of 18 packs of 25 envelopes would be:

18 packs x £3.29 per pack = £59.22

At Value World, the cost of 45 packs of 10 envelopes (with 15 packs being free) would be:

30 packs x £1.95 per pack = £58.50

Therefore, buying from Value World would cost Binita £59.22 - £58.50 = £0.72 less than buying from Letters2go.

Answers

The sequence {an} = {\(8n^4 + n + 1\)} is not convergent. It diverges to infinity as n approaches infinity.

To determine whether the sequence {an} = {\(8n^4 + n + 1\)} is convergent, we need to examine the behavior of the terms as n approaches infinity.

The sequence {an} is said to be convergent if there exists a real number L such that the terms of the sequence get arbitrarily close to L as n approaches infinity.

To investigate convergence, we can calculate the limit of the sequence as n approaches infinity.

lim(n→∞) \((8n^4 + n + 1)\)

To evaluate this limit, we can look at the highest power of n in the sequence, which is \(n^4.\) As n approaches infinity, the other terms (n and 1) become insignificant compared to n^4.

Taking the limit as n approaches infinity:

lim(n→∞) \(8n^4 + n + 1\)

= lim(n→∞) \(8n^4\)

Here, we can clearly see that the limit goes to infinity as n approaches infinity.

Therefore, the sequence {an} = {\(8n^4 + n + 1\)} is not convergent. It diverges to infinity as n approaches infinity.

if a typical somatic cell (somatic cell = typical body cell) has 64 chromosomes, how many chromosomes are expected in each gamete of that organism?

Answers

If a typical somatic cell has 64 chromosomes, each gamete of that organism is expected to have 32 chromosomes.

In sexually reproducing organisms, somatic cells are the cells that make up the body and contain a full set of chromosomes, which includes both sets of homologous chromosomes. Gametes, on the other hand, are the reproductive cells (sperm and egg) that contain half the number of chromosomes as somatic cells.

During the process of gamete formation, called meiosis, the number of chromosomes is halved. This reduction occurs in two stages: meiosis I and meiosis II. In meiosis I, the homologous chromosomes pair up and undergo crossing over, resulting in the shuffling of genetic material. Then, the homologous chromosomes separate, reducing the chromosome number by half. In meiosis II, similar to mitosis, the sister chromatids of each chromosome separate, resulting in the formation of four haploid daughter cells, which are the gametes.

Since a typical somatic cell has 64 chromosomes, the gametes produced through meiosis will have half that number, which is 32 chromosomes. These gametes, with 32 chromosomes, will combine during fertilization to restore the full set of chromosomes in the offspring, creating a diploid zygote with 64 chromosomes.

The water level in a tank measures 15 inches and is decreasing 0. 5 inches every minute. How many minutes, x, will it take for the water level to measure 9 inches deep?

Answers

The water level in the tank will take x = 30 minutes to decrease from 15 inches to 9 inches deep. It will take 6 minutes for the water level to decrease by 0.5 inches.

The water level in the tank is currently 15 inches deep and is decreasing by 0.5 inches every minute. In order to determine how many minutes, x, it will take for the water level to measure 9 inches deep, we will need to calculate the difference between the current water level and the desired water level. To do this, we need to subtract 9 inches from 15 inches, and this will give us a difference of 6 inches. Now, since the water level is decreasing by 0.5 inches per minute, we need to divide 6 inches by 0.5 inches, which will give us 12 minutes. Since 12 minutes is equal to 2 intervals of 6 minutes, the water level will take x = 30 minutes to decrease from 15 inches to 9 inches deep.

How can you tell that a point on a graph is neither a minimum or maximum?

Answers

Step-by-step explanation:

i think zero lol i dont know this is wrong or correct lol

Critical points can also be inflection points and you will have the slope changing signs, but the point is neither max nor min, it is just where the graph changes from concave up to concave down (the derivative there is either 0 or undefined).

Answers must be typed and uploaded to canvas as either a word document or PDF. Everybody needs to submit their own assignment and type up their own answers. Problem 1: Settler Mortality as an Instrument for Institutions There is a strong positive correlation in the data between the quality of a country's institutions and how developed a country is. Without additional investigation, however, it is difficult to determine whether there is a causal relationship and in what direction the causality goes. In this exercise we will use the instrumental variable approach of Acemoglu, Johnson, and Robinson (2001) to try and make a causal statement about whether institutions encourage growth and development. SETUP) This problem requires the use of Stata. Download the file Institutions.dta from my website and open it in Stata. The file is adapted from the data appendix of the paper mentioned above. Problem 1 Questions 1.a) Run a regression for the equation LGDP; = a + Pinst_qual Institution Quality; + where LGDP is log GDP per capita (PPP) in 1995 and Institution Quality is an index of Institution Quality in 1900 as, measured by average protection from expropriation risk. Report the estimated regression coefficients and their confidence intervals. What is the interpretation of Pinst_qual? What is the correlation between log GDP per Capita in 1995 and Institution Quality in 1900? 1.b) The values for Institution Quality in 1900 range from 3.5 to 10. According to the regression, what is the predicted value of GDP per Capita (not logged!) in 1995 for a country with a value of 10 for Institution Quality in 1900? What is the predicted value of GDP per capita in 1995 for a country with a value of 3.5 for Institution Quality in 1900? 1.c) Now we will run a 2SLS Instrumental Variable regression in STATA using Settler Mortality pre-1900 as an instrument for Institution Quality in 1900. What is the reasoning behind using Settler Mortality as an instrumental variable for institution quality? What is the correlation between the two variables? Report the new estimate of Binst_qual under the Instrumental Variable Regression. Why might the estimated regression coefficients differ? 1.d) What happened to the number of observations included in the regression compared to 1.a? What is if we re-run the regression in 1.a using only observations with data on settler mortality? Do the results change much?
