Suppose that a twenty-five-year-old woman, whose mother and aunts all were afflicted with breast cancer by the time they were 45, has a genetic test conducted at her own expense. the test reveals that she has inherited her mother's genetic susceptibility to breast cancer. after applying for employment and being given the position, her hr orientation includes registration for employer-paid health insurance. the insurance questionnaire asks if she suffers from any preexisting medical condition. what should the new employee answer? explain your answer.

Answers

The employee should answer that she does not suffer from any preexisting conditions. That is the simple truth. Just because she had a genetic test conducted to find out how susceptible she is to breast cancer, does not mean she is currently suffers from it- so she would not be lying. Furthermore, the genetic test is confidential. She can only be expected to answer if the HR department asks questions about her family history of illness/disease.

What is the current standard used in law enforcement for compressing fingerprint images?

Answers

Wavelet Scalar Quantization It is the standard developed by the FBI, Los Alamos National Laboratory, and the NIST and is used by most law enforcement agencies for the transmission and storage of fingerprints.
Final answer:

The Wavelet Scalar Quantization (WSQ) format, developed by the FBI, is the current standard for compressing fingerprint images in law enforcement. WSQ provides efficient transmission and storage of images, retaining high detail vital for fingerprint examination and matching, making it a preferred method in biometric applications.

Explanation:

The current standard used in law enforcement for compressing fingerprint images is the Wavelet Scalar Quantization (WSQ) format. Developed by the Federal Bureau of Investigation (FBI), WSQ provides a compression ratio of approximately 15:1, allowing for efficient transmission and storage of fingerprint images, without significant loss of fine detail and minutiae points vital for fingerprint examination and matching.

WSQ is favored over other compression methods (like JPEG or GIF) due to its handling of grayscale images that often characterize fingerprints, and for its emphasis on retaining high detail, even under considerable compression. By using a wavelet transformation technique, WSQ can distinguish small details in the image and retain them during compression, making it a gold standard in law enforcement and biometric applications.

The common stock of sweet treats is valued at $10.80 a share. the company increases its dividend by 8 percent annually and expects its next dividend to be $0.40 per share. what is the total rate of return on this stock?

Answers

Using the Gordon Growth Model (a.k.a. Dividend Discount Model), the intrinsic value of a stock can be calculated, exclusive of current market conditions. In this model, the value of the stock is equated to the present value of the stock's future dividends. 

Value of stock (P0) = D1 / (k - g)

where
D1 = expected annual dividend per share in the following year 
k = the investor's discount rate or required rate of return
g = the expected dividend growth rate 

From the problem:
The value of stock is $10.80
D1 is $0.40
g is 0.08

k is unknown

Solution:
Rearranging the equation for Gordon Growth Model to solve for k:

k = (D1/P0) + g

Substituting the variables with the given values, 

k = (0.40/10.80) + 0.08
k = 0.1170

In percent form, this is
0.1170 * 100% = 11.70%.

Thus, the total rate of return on the stock is 11.70%.

You have been asked to draw 600 cases from a population of 12,000. you decide on a systematic random sampling strategy. the sampling interval is:

Answers

To conduct a systematic random sampling out of the population, one should follow the following steps:
1. Create a list and assign numbers on every element in the population
       - Say a we assign cases 1 to 12,000

2. Decide the sample desired sample size
       - In our case, the sample size required is 600 cases

3. Select sampling interval
       - Simply divide the population with the sample size
       - 12,000/600 =20
       - Therefore, our sampling interval is 20. Meaning on every 20th element on the population we get to draw our pick until the desired sample size is accomplished.

Your $6100 investment grows to $12200 over the course of 9 years compounded quarterly. what interest rate did you receive on your investment? (write your answer with at least four decimal points)

Answers

The formula is
A=p (1+r/k)^kt
A future value 12200
P present value 6100
R interest rate ?
K compounded quarterly 4
T time 9 years

Set the equation and solve for r (interest rate)
12200=6100 (1+r/4)^(4×9)
Divide both sides by 6100
12200/6100=(1+r/4)^(36)
2=(1+r/4)^(36)
Take the root of 36 for both sides
2^(1/36)=1+r/4
R= (2^(1/36)-1)×4
R=(2^(1÷36)−1)×4
R=0.0778×100
R=7.78%

Hope it helps!
Final answer:

By using the compound interest formula and solving for the interest rate 'r', it can be determined that the interest rate received on an investment that grows from $6100 to $12200 over the course of 9 years compounded quarterly is 4.76%.

Explanation:

This is a problem of finding the interest rate in a compound interest formula. The formula for compound interest is A = P(1 + r/n)^(nt), where A is the amount of money accumulated after n years, including interest, P is the principal amount (the initial amount of money), r is the annual interest rate (in decimal), n is the number of times that interest is compounded per year, and t is the time the money is invested for in years.

In this problem, A is $12,200, P is $6,100, n is 4 (since interest is compounded quarterly), and t is 9 years. By plugging in these values into the formula, we can set up the equation: 12200 = 6100(1 + r/4)^(4*9). Solving for r gives us an interest rate of approximately 0.0476, or 4.76% when expressed as a percentage.

As with measures of centrality, the selection of a measure of variability should be based on

Answers

Final answer:

As with measures of centrality, the selection of a measure of variability should be based on the specific characteristics and needs of the data analysis being performed.

Explanation:

Measures of variability, such as variance and standard deviation, describe how spread out or dispersed the data are, which is critical in biological inquiry. Different types of variability like measurement variability, natural variability, induced variability, or sampling variability may influence the outcomes and should be considered when selecting a measure of variability.

Moreover, the decision should take into account the regularities in the object being measured and other factors that affect the outcome, including the accuracy, precision, sensitivity, and selectivity of the measurement method. The chosen measure should provide a valid representation (i.e. that measures what you are trying to measure with minimal influence from other factors) of the biological concept under investigation.

Was life easier for teenagers 50 years ago than it is for teenagers today?

Answers

No because they didn't have as much as the new generation does

Final answer:

Life for teenagers today is certainly different than it was 50 years ago. With the advancement of technology, teenagers today have access to tools and resources that were not available to teenagers in the past. However, along with these benefits come new challenges.

Explanation:

Life for teenagers today is certainly different than it was 50 years ago. With the advancement of technology, teenagers today have access to tools and resources that were not available to teenagers in the past. For example, the internet provides a wealth of information and opportunities for communication and learning. However, along with these benefits come new challenges.


One major challenge for teenagers today is the pressure to constantly be connected and available. With smartphones and social media, teenagers are expected to be constantly connected to their peers and are often subject to cyberbullying and online criticism. Comparatively, teenagers 50 years ago did not have this level of constant connectivity and pressure.


Another aspect to consider is the societal and cultural changes that have taken place over the past 50 years. For example, attitudes towards issues like gender roles, sexuality, and diversity have evolved significantly. This can create both opportunities for teenagers today to express themselves and face less discrimination, but it can also lead to new forms of discrimination and challenges. Additionally, the increased pace of life and globalization has resulted in more competition and higher expectations for success in academics, extracurriculars, and future career prospects.

Rex's doughnuts can produce only 100 doughnuts a day. the variable cost incurred per unit is $2 and fixed costs incurred per day is $500. at what price should a doughnut be sold to break even?

Answers

The total cost that is incurred by producing 100 doughnuts is equal to the sum of the variable cost and the fixed cost. The total variable cost is,
    total variable cost = ($2/doughnut)(100 doughnuts) = $200

The total cost is,
   Total cost = total variable cost + total fixed cost
     TC = $200 + $500 = $700

Equating the cost and the revenue,
     TC = TR
     $700 = (100)(x)

The value of x from the equation is $7.

ANSWER: $7. 
Final answer:

To break even, the price of Rex's doughnuts should be settled at $7, calculated by dividing the total cost ($700) by the number of doughnuts (100).

Explanation:

In order to calculate the break-even price for Rex's doughnuts, we need to understand the concept of variable and fixed costs. In this scenario, the variable cost per unit is given as $2 per doughnut, and the fixed costs per day are $500. The total production capacity is 100 doughnuts per day.

The total variable cost (TVC) is variable cost per unit multiplied by the number of units produced. In this case, it would be 100 doughnuts * $2 = $200. The total cost (TC) will be the sum of total variable cost and fixed cost, which is $700 ($200 + $500).

To break even, the total revenues (TR) Rex earns from selling the doughnuts should be equal to the total cost. Knowing that he can only produce 100 doughnuts a day, the break-even price per doughnut (P) should be Total Cost (TC) divided by the number of doughnuts. Therefore, P = TC/ 100 doughnuts = $700 / 100 = $7.

Hence, Rex should sell each doughnut for $7 to break even.

When public saving falls by $2b and private saving falls by $1b in a closed economy,?

Answers

Final answer:

In a closed economy, a decrease in public and private savings by $3 billion in total reduces national saving, affecting the economy's ability to finance investment. According to the national saving and investment identity, saving must equal investment, so any deficit requires more borrowing or foreign investment.

Explanation:

Changes in Public and Private Savings

In a closed economy, the national saving is the sum of public saving (the government budget surplus or deficit) and private saving (the savings of individuals and businesses). When public saving falls by $2 billion and private saving falls by $1 billion, the overall national saving decreases by $3 billion. This impacts the economy's ability to finance domestic investment without relying on foreign investment.

National Saving and Investment Identity

According to the national saving and investment identity, for a closed economy, saving must equal investment. Therefore, if public and private saving decreases, there would need to be either a decrease in domestic investment or an increase in borrowing to finance the unchanged level of investment.

Example Scenario

Considering the example scenario provided, with a $100 billion government budget deficit, $1,500 billion in total domestic savings, and $1,600 billion in total domestic physical capital investment:

The current account balance is negative, indicating a deficit in national savings compared to investment.

If investment rises by $50 billion, while the deficit and national savings remain the same, the current account balance will further worsen, indicating the need for the economy to borrow more or attract foreign investment to finance the additional investment.
