Answer:
Redshift is a phenomenon which causes the light from galaxies which are moving away from the Earth to have a longer measured wavelength than the emitted light.
Explanation:
A redshift reveals how an object in space star,planet,galaxyis moving compared to us. It lets astronomers measure a distance for the most distant
sorry if wrong trying my best
The concept of redshift reveals how an object in space whether a star, planet or galaxy is moving compared to us.
Redshift allows astronomers to measure the distance for the most distant and oldest objects in our universe.
'Red shift' is a key concept for astronomers. The term can be understood literally - the wavelength of the light is stretched, so the light is seen as 'shifted' towards the red part of the spectrum.
The greater its redshift, the faster the object recedes . The phenomenon of redshift is due to the Doppler effect. When an object emitting electromagnetic radiation recedes from an observer redshift occurs.
The detected light appears "redder" than it is estimated to be because it is shifted toward the "red" end of the spectrum.

A community diagnosis survey conducted in “X” district, 01 Kebele, in 2004; provided the data below:
Total population at the Beginning of the year = 80,000
Total popn at the end of the year …………… = 100,000
Number of female popn ……………………. = 40,000
Total deaths ……………………………….... = 2000
Total female deaths ……………………….... = 1000
Number of live births ……………………… = 1600
Number of infant deaths …………………… = 120
Deaths due to TB …………………………… = 50
Number of TB cases ………………………... = 200
Calculate:
12.1. The crude death rate 12.2. The females’ death rate
12.3. The Cause specific death rate (Tuberculosis) 12.4. The infant mortality rate
12.5. The case fatality rate of tuberculosis
Answer:
Explanation:
12.1. The crude death rate: The crude death rate is calculated by dividing the total number of deaths in the population by the total population and multiplying the result by 1000. In this example, the crude death rate would be calculated as follows: Crude death rate = (2000 / 80000) * 1000 = 25 deaths per 1000 population.
12.2. The female death rate: The female death rate is calculated by dividing the number of female deaths in the population by the total number of female population and multiplying the result by 1000. In this example, the female death rate would be calculated as follows: Female death rate = (1000 / 40000) * 1000 = 25 deaths per 1000 female population.
12.3. The Cause specific death rate (Tuberculosis): The cause specific death rate for tuberculosis is calculated by dividing the number of deaths due to tuberculosis by the total population and multiplying the result by 1000. In this example, the cause specific death rate for tuberculosis would be calculated as follows: Cause specific death rate (tuberculosis) = (50 / 80000) * 1000 = 0.625 deaths per 1000 population due to tuberculosis.
12.4. The infant mortality rate: The infant mortality rate is calculated by dividing the number of infant deaths by the total number of live births and multiplying the result by 1000. In this example, the infant mortality rate would be calculated as follows: Infant mortality rate = (120 / 1600) * 1000 = 75 infant deaths per 1000 live births.
12.5. The case fatality rate of tuberculosis: The case fatality rate of tuberculosis is calculated by dividing the number of deaths due to tuberculosis by the total number of tuberculosis cases and multiplying the result by 100. In this example, the case fatality rate of tuberculosis would be calculated as follows: Case fatality rate (tuberculosis) = (50 / 200) * 100 = 25% case fatality rate of tuberculosis.

A large hamburgers sandwich contains 628 kcal and 36 grams of fats. Qs approximately what percentage of the total energy is contributed to by fat
Approximately 51.6% of the total energy in the large hamburger sandwich is contributed by fat.
How calculate of the total energy in the large hamburger?To find the percentage of total energy contributed by fat in the large hamburger sandwich, you need to divide the number of calories from fat by the total number of calories and multiply by 100:
% of total energy from fat = (fat calories / total calories) * 100
The number of calories from fat in the sandwich can be found by multiplying the number of grams of fat by 9 (since 1 gram of fat provides 9 calories).
fat calories = 36 grams * 9 calories/gram = 324 calories
Then you can use the formula to find the percentage of total energy from fat:
% of total energy from fat = (324 calories / 628 calories) * 100 = 51.6%
Approximately 51.6% of the total energy in the large hamburger sandwich is contributed by fat.

In your own words, briefly explain the difference in medical decision-making for ED physicians versus physicians of other specialties as described in your assigned reading this week.
Answer:
The difference in medical decision-making for Emergency Department (ED) physicians versus physicians of other specialties is primarily based on the level of complexity and acuity of the patient's condition. Emergency Department physicians are often required to quickly assess and treat patients with a wide range of acute illnesses and injuries, many of which may be life-threatening. In such cases, ED physicians need to make complex medical decisions in a short amount of time, often without the benefit of a detailed medical history or prior examination of the patient.
On the other hand, physicians of other specialties, such as primary care or specialists, may have the luxury of more time to evaluate and treat a patient, as well as access to more detailed medical history, prior examination, and lab test results.

1. To investigate the association between ascariasis and hand wash investigators conducted a case-control study with 100 cases (100 children with stool-test Positive) and 100 controls (100 children Negative). Among Positives children, 50 gave a history of exposure (frequent hand washes). Among those Negatives, 25 gave a history of exposure to hand washes.
For this study, calculate the odds ratio & interpret the result.
To calculate the odds ratio (OR) for the association between ascariasis and hand washing in this case-control study, we can use the following formula:
OR = (a/c) / (b/d)
Where:
a = number of cases with exposure (frequent hand washing) = 50
b = number of cases without exposure (not frequent hand washing) = 50
c = number of controls with exposure (frequent hand washing) = 25
d = number of controls without exposure (not frequent hand washing) = 75
Plugging in these values into the formula:
OR = (50/25) / (50/75)
OR = 2
This means that the odds of having ascariasis among children who frequently wash their hands are 2 times higher than the odds of having ascariasis among children who do not frequently wash their hands.
In terms of interpretation, an OR of 2 means that frequent hand washing is associated with a twofold increase in the odds of having ascariasis. However, it should be kept in mind that this association does not necessarily imply causality, and other factors might be involved. Additionally, the study design of a case-control study may have its own limitations, such as recall bias or selection bias, so it would be important to consider these factors when interpreting the results.
I hope this helps :)
1. Interpret the following values:
a. RR= 0.5
b. RR= 2
c. OR = 3
a. RR (Relative Risk) of 0.5 indicates that the risk of an event occurring in the group being studied is half the risk of the event occurring in the comparison group.
b. RR of 2 indicates that the risk of an event occurring in the group being studied is twice the risk of the event occurring in the comparison group.
c. OR (Odds Ratio) of 3 indicates that the odds of an event occurring in the group being studied are three times the odds of the event occurring in the comparison group.
What is the risk ratio?A risk ratio (RR), also known as a relative risk, contrasts the risk of a health event (such as a disease, injury, risk factor, or death) among two groups. The risk (incidence proportion, attack rate) in group 1 is divided by the risk (incidence proportion, attack rate) in group 2, and the result is the calculated risk.
The odds ratio is described as the proportion of the odds of A occurring when B is present to the odds of A occurring when B is absent, or alternatively (due to symmetry).

Describe regressive, proportional, and progressive
financing. Explain how each of the following is
regressive, proportional, or progressive: out-of-
pocket payments, experience-rated individual pri-
vate insurance, community-rated individual private
insurance, health insurance purchased 100% by the
employer (assuming that employees actually pay for
health insurance as explained in the text), and the
federal income tax.
Answer:
Regressive financing is when the amount of money paid increases in relation to the amount of money earned. For example, a person who earns $50,000 a year might pay 10% of their income in taxes, while a person who earns $20,000 a year might pay 20% of their income in taxes.
Proportional financing is when the amount of money paid is the same regardless of the amount of money earned. For example, a person who earns $50,000 a year might pay the same amount of taxes as a person who earns $20,000 a year.
Progressive financing is when the amount of money paid increases in relation to the amount of money earned. For example, a person who earns $50,000 a year might pay 15% of their income in taxes, while a person who earns $20,000 a year might pay 10% of their income in taxes.
Out-of-pocket payments are regressive, since the amount of money paid increases in relation to the amount of money earned. Experience-rated individual private insurance is proportional, since the amount of money paid is the same regardless of the amount of money earned. Community-rated individual private insurance is also proportional, since the amount of money paid is the same regardless of the amount of money earned. Health insurance purchased 100% by the employer is regressive, since the amount of money paid increases in relation to the amount of money earned. The federal income tax is progressive, since the amount of money paid increases in relation to the amount of money earned.
