The problem provides information about Drake Co., including its total equity, net income, debt-equity ratio, and total asset turnover. The task is to calculate the profit margin. Therefore, the correct answer is option A) 3.72%
The profit margin can be determined by dividing the net income by the total revenue. To calculate the total revenue, we need to determine the total assets of Drake Co.
Given the debt-equity ratio of 0.50, we can calculate the debt and equity amounts. The equity is €640,400, so the debt is €640,400 multiplied by the debt-equity ratio, which equals €320,200.
To find the total assets, we sum the equity and debt: €640,400 + €320,200 = €960,600.
Using the total asset turnover, which is 1.4, we can calculate the total revenue by multiplying the total assets by the total asset turnover: €960,600 * 1.4 = €1,344,840.
Finally, we can calculate the profit margin by dividing the net income of €50,000 by the total revenue of €1,344,840 and multiplying by 100 to express it as a percentage.
Profit margin = (Net income / Total revenue) * 100
Profit margin = (€50,000 / €1,344,840) * 100
Profit margin ≈ 3.72%
Therefore, the correct answer is option A) 3.72%, which represents the profit margin for Drake Co. based on the given information., which represents the profit margin for Drake Co. based on the given information.

Let R be the binary relation defined on a set of all integers Z as follows: for all integers m and n, mRn m’ – n’ is divisible by 6. a) Is R an equivalence relation? Check the conditions. b) What is the equivalence class of -17?
Previous question
The required solutions are:
a) Yes, the relation R is an equivalence relation.
b)The equivalence class of -17 is {-17, -23, -29, -35, ...}.
a) In order to determine whether R is an equivalence relation or not, we need to check if it satisfies the following three conditions:
Reflexibility: For all integers m, mRm should hold. In the given case, if we take m=n, we have m-n=n-m=0, which is divisible by 6. So, we can see that the reflexibility is satisfied.Transitivity: For all integers m, n, and p, if mRn and nRp hold, then mRp should also hold. Assume mRn and nRp, which means m-n, and n-p are both divisible by 6. To check transitivity, we need to check if m - p is divisible by 6. By adding the two previous conditions, we have (m-n) + (n-p) = m-p, which is also divisible by 6. Therefore, transitivity is satisfied.Symmetry: For all integers m and n, if mRn holds, then nRm should also hold. If mRn, it means m-n is divisible by 6. In order to check the symmetry, we need to check if n - m is divisible by 6. We can use the fact that a-b = -(b-a), we can rewrite n - m as -(m - n), which is divisible by 6. So, we can say that symmetry is satisfied.We can see that the relation 'R' satisfies all the conditions ( reflexibility, symmetry, and transitivity), so R is an equivalence relation.
b) In order to find the equivalence class of -17, we need to find all integers that are related to -17 under the relation R.
We can rewrite the relation as mRn if and only if m' - n' = 6k for some integer k.
In this case, -17Rn if and only if (-17)' - n' = -17 - n = 6k for some integer k.
To find all integers n that satisfy this equation, we can rearrange it as n = -17 - 6k.
By putting in different values of k, we can find all the integers n that are in the equivalence class of -17.
For example, when k = 0, n = -17 - 6(0) = -17. So, -17 is in the equivalence class of -17.
We can also see that when k = 1, n = -17 - 6(1) = -23. So, -23 is also in the equivalence class of -17.
The equivalence class of -17 consists of all integers that can be obtained by subtracting multiples of 6 from -17. So, the equivalence class of -17 is {-17, -23, -29, -35, ...}.

Q.1.1.5 The probability of selecting a respondent who does not prefer Lenovo is 0.725.
Q.1.1.1 What is the probability of randomly selecting a male respondent from the sample?
The probability of randomly selecting a male respondent is given by the number of male respondents divided by the total number of respondents:
Probability = No. of Males / Total = 160 / 400 = 0.4
Q.1.1.2 What is the probability of randomly selecting a respondent who is female and prefers HP?
The probability of randomly selecting a respondent who is female and prefers HP is given by the number of females who prefer HP divided by the total number of respondents:
Probability = No. of Females who prefer HP / Total = 110 / 400 = 0.275
Q.1.1.3 What is the probability of selecting a male respondent, given that the preferred brand is Lenovo?
The probability of selecting a male respondent, given that the preferred brand is Lenovo, is given by the number of males who prefer Lenovo divided by the total number of respondents who prefer Lenovo:
Probability = No. of Males who prefer Lenovo / Total No. of respondents who prefer Lenovo = 50 / 110 = 0.4545
Q.1.1.4 What is the probability of selecting a respondent who is male or who prefers HP?
The probability of selecting a respondent who is male or who prefers HP is given by the sum of the probabilities of selecting a male respondent and selecting a respondent who prefers HP, minus the probability of selecting both (to avoid double counting):
Probability = (No. of Males / Total) + (No. of Females who prefer HP / Total) - (No. of Males who prefer HP / Total)
Probability = (160 / 400) + (110 / 400) - (40 / 400) = 0.4 + 0.275 - 0.1 = 0.575
Q.1.1.5 What is the probability of selecting a respondent who does not prefer Lenovo?
The probability of selecting a respondent who does not prefer Lenovo is given by the number of respondents who do not prefer Lenovo divided by the total number of respondents:
Probability = (Total - No. of respondents who prefer Lenovo) / Total
Probability = (400 - 110) / 400 = 290 / 400 = 0.725

The Σx = 68, y = 79, xy = 1200 x² = 600 and N = 12 determine the equation of the least square line. Leave answer in 2 decimal places.
To determine the equation of the least squares line, we need to find the slope (m) and the y-intercept (b) using the given data. The formula for the least squares line is:
y = mx + b
where:
m is the slope of the line
b is the y-intercept of the line
We can use the following formulas to calculate the slope and y-intercept:
m = (NΣxy - ΣxΣy) / (NΣx² - (Σx)²)
b = (Σy - mΣx) / N
Given the values:
Σx = 68
Σy = 79
Σxy = 1200
Σx² = 600
N = 12
Let's substitute these values into the formulas:
m = (12 * 1200 - 68 * 79) / (12 * 600 - (68)²)
b = (79 - m * 68) / 12
Calculating the values:
m = (14400 - 5372) / (7200 - 4624)
m = 9028 / 2576
m ≈ 3.5039
b = (79 - 3.5039 * 68) / 12
b = (79 - 238.2752) / 12
b ≈ -13.2738
Therefore, the equation of the least squares line is:
y ≈ 3.5039x - 13.2738

The equation of the least squares line is y = 1.25x + 10.75
To determine the equation of the least squares line, we need to find the slope (b) and y-intercept (a) using the following formulas:
b = (NΣxy - ΣxΣy) / (NΣx² - (Σx)²)
a = (Σy - bΣx) / N
Given the following values:
Σx = 68
Σy = 79
Σxy = 1200
Σx² = 600
N = 12
Let's calculate the slope (b) first:
b = (12 × 1200 - 68×79) / (12×600 - 68²)
b ≈ 1.25
Now we can calculate the y-intercept (a):
a = (79 - 1.25×68) / 12
a = 10.75
Therefore, the equation of the least squares line is: y = 1.25x + 10.75.

Previous question
The mathematical relationship between the relative risk (RR) and the odds ratio (OR) is (c) The relative odds approach.
How to find the mathematical relationship between the relative risk (RR) and the odds ratio (OR)?The mathematical relationship between the relative risk (RR) and the odds ratio (OR) is often described as the relative odds approach.
This approach quantifies the relationship between RR and OR and provides insights into the association between exposure and outcome in observational studies.
The rare disease assumption (a) refers to the assumption made in case-control studies that the odds ratio approximates the relative risk when the outcome is rare.
It is not specifically related to the mathematical relationship between RR and OR.
The built-in bias (b) does not directly relate to the mathematical relationship between RR and OR.
It refers to biases inherent in the study design or data collection process.
Effect modification (d) refers to a situation where the association between an exposure and outcome differs depending on the levels of another variable.
While effect modification can influence the relationship between RR and OR, it is not the specific term used to describe their mathematical relationship.
In summary, the mathematical relationship between RR and OR is best described as the relative odds approach (c), while the other options (a, b, d) are not directly related to this specific relationship.
