Case definition of coronary heart disease: For a case definition for coronary heart disease, the definition should include an individual having the clinical findings of the disease such as chest discomfort, cardiac enzymes, and EKG changes.

Other criteria could be the need for invasive interventions such as coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI).

Since coronary heart disease is a leading cause of death in Scandinavian countries, it is important to have a clear and concise case definition to help better classify and study these types of diseases.

The criteria for this case definition should include clinical, laboratory, and invasive procedures to identify cases of coronary heart disease.

The measure of disease:

For Norway, the measure of disease that can be calculated is the death rate.

The death rate is a measure of the frequency of occurrence of death in a defined population during a specified period.

It is calculated by dividing the number of deaths in a population by the total population at risk and expressed as the number of deaths per unit of the population.

For Norway, the death rate due to coronary heart disease in 2018 would be calculated by dividing the total number of deaths due to coronary heart disease in 2018 (6,106) by the total population in Norway in 2018 (5,215,000) and multiplying the result by 100,000 to get the rate per 100,000 population:

Death rate due to coronary heart disease in Norway in 2018 = (6,106 / 5,215,000) x 100,000 = 117 deaths per 100,000 population.

Since the company wants to predict ads used from units, the explanatory variable is ads used is the explanatory or predictor variable. Option D is correct. Since the company wants to predict ads used from units, the response variable is units is the response variable. Option B is correct. Since ads used is the explanatory variable, it should be plotted on the X-axis. Option A is correct.

a) Since the company wants to predict ads used from units, the explanatory variable is ads used. The company is interested in understanding how the amount spent on advertising (explanatory variable) influences the number of ads used (response variable).

By analyzing this relationship, they can determine the impact of their advertising budget on the number of ads utilized. Thus, option D is correct.

b) Since the company wants to predict ads used from units, the response variable is units. The response variable is the one that the company wants to predict or understand based on the explanatory variable.

In this case, the company wants to predict the number of ads used based on the units, which refers to the amount spent on advertising. Thus, option B is correct.

c) Since ads used is the explanatory variable, it should be plotted on the x-axis. In a scatter plot, the explanatory variable is typically plotted on the x-axis, while the response variable is plotted on the y-axis. Thus, option A is correct.

In this scenario, the company would plot the number of ads used (ads used) on the x-axis and the amount spent on advertising (units) on the y-axis. This allows them to visualize the relationship between the two variables and analyze how the amount spent on advertising affects the number of ads used.

Conclusion: The relationship between the amount spent on advertising and revenue can be analyzed by considering the number of ads used as the explanatory variable and the units (amount spent on advertising) as the response variable.

By plotting the number of ads used on the x-axis and the units on the y-axis, the company can observe any patterns or trends in the data and gain insights into the impact of their advertising expenditures on revenue generation.

Answer: for this question we do 102/850 which equals 12%

Step-by-step explanation: Yes, because it is close to the percentage.

Answer: x = 2√381

Step-by-step explanation:

Call A the dotted line.

Using the Pythagorean theorem, we find that \(A^{2} + 16^{2}\) \(= 22^{2}\)

Simplifying gives:

\(A = \sqrt{16^2 + 22^2}\\A = \sqrt{740}\\A = 2\sqrt{185}\)

Now we move to the other triangle we can call the sides: a, the dotted side, b the height, and x, the hypotenuse.

\(a = 2\sqrt{185}\)

and

\(b = 44-16 = 28\)

So,

\((2\sqrt{185})^{2} + 28^2 = x^2\\x = \sqrt{(2\sqrt{185})^2 +28^2 }\\x = \sqrt{740+784}\\x= \sqrt{1524}\\x= 2\sqrt{381}\)

Answer:

x = 32

Step-by-step explanation:

So we are given the measures of two of the three interior angles. 98° and 50°. We are also given that the value of the third interior angle is equal to x°. Remember, the sum of the interior angles of a triangle is 180°. Knowing this, we can make the equation:

x + 98 + 50 = 180

Now we solve for x. Subtract 50 from both sides.

x + 98 = 130

Subtract 98 from both sides.

x = 32

So the value of x is 32.

Answer:

Answer:B

Step-by-step explanation:

The correct answer is: d. No, because 3 inches falls above the maximum value of lengths in the sample.

In linear regression, the model is based on the relationship observed in the sample data. The biologist collected data on fish lengths ranging from 0.75 to 1.35 inches, so the model is only valid within that range. Extrapolating the model to predict the weight of a fish with a length of 3 inches would be beyond the observed range of the data. This can lead to unreliable predictions as the relationship between length and weight may not hold true for lengths beyond the range of the sample.

The value of t would be,

⇒ t = 1.761

Using a table or calculator, we can find the value of t that corresponds to an area of 0.05 in the right tail of the t-distribution with 14 degrees of freedom.

The table or calculator will provide us with the t-value and its corresponding area in the right tail of the distribution.

Since we want an area of 0.05 in the right tail, we need to look for the t-value that has an area of 0.05 to the left of it.

Hence, Using a t-table, we find that the t-value with 14 degrees of freedom and an area of 0.05 in the right tail is approximately 1.761.

Therefore, t = 1.761 rounded to 3 decimal places.

To calculate the profit on a specific day, simply plug the day number (x) into the equation and solve for f(x). For example, to find the profit on the third day (x=3), you would use the equation:

The equation provided, f(x) = 20x - 120, represents the daily profit of Douglas's lemonade stand, where x is the number of days after opening and f(x) is the profit in dollars.


f(3) = 20(3) - 120

f(3) = 60 - 120

f(3) = -60

On the third day, Douglas has a loss of $60. As time goes on, you can expect the profit to increase because of the positive 20x term in the equation. Eventually, Douglas's lemonade stand will start to make a profit. To find the break-even point, set the profit (f(x)) equal to zero and solve for x:

0 = 20x - 120

120 = 20x

x = 6

Douglas will break even on the 6th day, meaning he will start making a profit from the 7th day onward. By understanding the equation and plugging in values for x, you can calculate the profit for any number of days after opening the lemonade stand.

Given an angle that is positive, less than 360°, and coterminal with 395° is 35°.

Subtract 360° from 395°.

We know that 1 revolution is equal to 360°.

Therefore, a positive angle that is less than 360° and coterminal with 395° is 35°.

When an angle is less than 360° and shares the same terminal side with another angle that is less than 360°, then the angle is referred to as a coterminal angle.

In other words, the two angles have the same initial side and terminal side but can be either positive or negative.

15% discount

Step-by-step explanation:

Given:- Prices for a day ticket entrance at Disneyland Paris resort are

adult=55

child=45

family(2 adults ,2 children)=170

To find:- The family discount in percentage

Solution:- According to the question, Prices for a day ticket entrance at Disneyland Paris resort are

adult=55

child=45

So the price for two adults is 2×55=110

and the price for two child is 45×2= 90

but for the family(2 adults ,2 children),the price is 170

So, though the number of members are same but here a family is getting (110+90-170)=30 rupees less than the actual price (200)

so the discount is 100×30/200 =15%

So the family will get 15% discount.

Answer: The first answer is correct

Step-by-step explanation:

Answer:

a is 30 degrees.

Step-by-step explanation:

The degree of a triangle is 180, which means that all the degrees in any triangle will always add up to 180. Since CB and DB are congruent, the angles C and D will be the same. This means that to get the answer, just subtract the value we already have from 180 and divide the sum by 2.

\(\frac{180-120}{2} = \frac{60}{2} = 30\)

To ensure that only the original hole is patterned in the second direction and not the patterned holes, select the "Seed Only" or "Pattern Seed Only" check box when creating the pattern in your CAD software.

The check box selected to ensure that only the original hole is patterned in the second direction and not the patterned holes is typically called the "Seed Only" or "Pattern Seed Only" option.

Here is a step-by-step explanation:

1. In a CAD (Computer-Aided Design) software, you may have created an original hole and then used the "Pattern" or "Pattern Holes" feature to create a pattern of holes in one direction.

2. Now, you want to create a pattern of this original hole in the second direction, but you do not want to pattern the holes that were already created in the first direction.

3. In the pattern settings or options, you will find a check box called "Seed Only" or "Pattern Seed Only." This option is specifically designed for situations like yours, where you only want to pattern the original hole and not the other holes created by previous patterns.

4. Check the "Seed Only" or "Pattern Seed Only" option to make sure that the software knows to pattern only the original hole in the second direction.

5. Proceed with setting the pattern direction, distance, and the number of instances or copies of the hole you want in the second direction.

6. After confirming the settings, the software will create a pattern of the original hole in the second direction without patterning the previously created holes from the first direction.
