We have that

Sheri's age=x

terry's age=y

 in 20 years

x+20 <span>=y   equation 1</span>

 in 10 years

y+10<span>=2*x   equation 2</span>

 resolving

 y=x+20  equation 1

 y=2*x-10 equation 2

 x+20 =2*x-10

2*x-x=20+10

x=30

y=x+20--------------y=30+20=50

Sheri's age=x------------------30 years

terry's age<span>=y-------------------50 years</span>

Due to past abuses, which of the following groups of potential research subjects has specific Department of Health and Human Ser
Andrej [43]

Answer:

prisoners

Explanation:

Prisoners have been popular victims(research subjects) of illegal research in the past and so laws have been put in place to prevent this.

Prisoners are classified as "vulnerable" under federal regulations that regulate research with prisoners. This is because their informed consent and voluntary decision to participate in any research brought before them is somewhat compromised. The health and human services(HHS) in addition to other regulations have added additional requirements for research on prisoners such as the requirement of a prisoner or prisoner representative in the IRB.

tatiyna

Answer:

When the schools are reviwed the only action that represents a less structured approach that teachers use is:

Explanation:

First of all, we need to understand the question. We need to find the worst structured approach teachers use. The structure depends on the organization of the activity. That is the measure we take into account to define which one is the worst.

a) asking questions of the students. This is the less structured approach because not all of them will work, only a few will do, also the questions will be open and the teacher can't control or orientate the curse of their questions because he has no control over their minds.

b) allowing the students to work in small groups requires rules, requires an objective, requires an organization, a distribution of the activities, an objective, and the analysis of information to create a learning experience. So it's incorrect.

c) Presenting materials to the students require a high level of organization because they need to explain a topic and organize the information to make sure they understand the message. So this is incorrect.

d) This is a highly structured activity because the activities take the curriculum as an object to create the activities and achieve the objectives of the curriculum so it's incorrect.

Hello. You forgot to add the answer options. The response options are:

" Common Terminology . Modular Organization . Incident Action Planning . Integrated Communications . Unified Command . Information and Intelligence Management "

Answer:

  • Modular Organization
  • Information and Intelligence Management

Explanation:

NIMS Management is a set of methods and guidelines that allow quick maintenance and efficient management of a certain area with the main objective of preventing or reducing the incidence of incidents, whether they are health problems, infrastructure problems, among others. In summary, NIMS has as main objective to promote a quick response to any type of energy that may occur within the national territory.

As you can see above, a region is showing a serious health problem that can result in an epidemic, causing serious problems to the population. In this case, NIMS allows a number of different organizations to work together, to understand what is happening with the situation by searching for information that allows a solution to be developed as quickly as possible.

In the case shown in the question above, the characteristics of the NIMS management that are being used are Modular Organization (allowing the involvement of several organizational entities in solving the problem) and Information and Intelligence Management (which allows a wide and quick search for relevant information that will help solve the problem).
