## Mathematics Question

For this activity you will work in groups to complete a sample THIRA.

For this discussion activity, you will complete a sample THIRA using the four-step process. Use the THIRA worksheets download[Docx, File size 12.2 KB] provided to record your findings. Refer to your text, Chapter 9 and the Comprehensive Preparedness Guide 201: Threat and Hazard Identification and Risk Assessment (THIRA) Process Guide for examples

STEP 1: Identify Threats and Hazards

In your group, create a list of jurisdictional threats and hazards. Each group will be assigned a local jurisdiction, and should choose three threats and three hazards, one from each category (natural, technological, and human-caused).

STEP 2: Contextualize Threats and Hazards

Each group will then chose one incident from the list of three threats and hazards of significant concern identified in activity one and create a context description. This should include the conditions (at a minimum time and location) most relevant to the community. Use table 9.5 Threat and Hazard Description factors (found in chapter 9 of your text) to develop your context descriptions.

STEP 3: Establish Capability Targets

3.1 Estimate Impacts of a Threat of Hazard: Using the context descriptions developed in Step 2, choose five (5) core capabilities, one from each of the five mission areas (prevent, protect, mitigation, response, and recovery) that would pertain to managing the threat or hazard (see Table 9.1 in your text). Next, estimate impacts of the threat or hazard on the chosen capabilities.

3.2 Develop Desired Outcomes and Capability Target Statements: Using all of the information created in the previous activities, each team will develop one desired outcome for each of the five core capabilities identified in the Estimate Impacts of a Threat of Hazard activity (above). Use the estimated impacts and the desired outcomes to develop one capability target statement for each of the core capabilities.

STEP 4: Apply the Results

Apply The Results: Using the capability target statements from each of the core capabilities previously identified in Step 3, identify the necessary resources needed to request, deploy, and use to manage your incident. Your team will need to use the FEMA Resource Typing Library Tool (Links to an external site.). Calculate the resource requirements by considering the capability targets, operational capacities of resources, and time available. Present your final THIRA results to the class.

Post your findings using the THIRA Worksheet EditEdit download[Docx, File size 12.2 KB] to the discussion board.

PART B

Prepare a Threat and Hazard Identification and Risk Assessment (THIRA) calculation and summary paper for two of the threats not used by your group in the discussion forum (natural, technological, and human caused). This is an individual assignment. You are to explain each step of the process for your threat/hazard in the same format you used for the discussion activity:

Identify threats and hazards of concern

Give the threats and hazards context

Establish capability targets

Apply the results.

Refer to your text, Chapter 9 and the Comprehensive Preparedness Guide 201: Threat and Hazard Identification and Risk Assessment (THIRA) Process Guide for examples. You may use the same worksheets download[Docx, File size 12.2 KB] provided for the group discussion activity for the calculation section.

Once you have completed the THIRA calculation for each threat/hazard, you will write must include a 1-2 page summary for each that includes a brief proposal of strategies or activities that might be taken to reduce the risks to that particular area. The finished calculation and summary paper should be 4-5 pages in length.

## Statistics short answer questions (DUE IN 3 HOURS)

These are short answer questions.

4.) Explain how to generate a simple random sample of 20 employees out of the 85 total

employees who are working at a candy bar factory.

5.) Explain how generating a simple random sample of 20 candy bars off the production line

would be different than generating a simple random sample of 20 employees.

6.) Explain why sampling without replacement is preferable to sampling with replacement

7.) Provide an example of when you might want to take a systematic random sample

instead of a simple random sample, and explain what the advantages of a systematic

random sample might be.

8.) Provide an example of when you might want to take a stratified random sample instead of

a simple random sample, and explain what the advantages of a stratified random sample

might be.

9.) Provide an example of when you might want to take a cluster random sample instead of a

simple random sample, and explain what the advantages of a cluster sample might be.

Also, explain how you would choose the cluster sample.

10.) A telephone survey evaluating unemployment claims asks the question, “Do you think

people should be paid not to work?” The survey was conducted during the hours of 8:00

am to 4:00 pm for homeowners with listed landlines. What are some possible sources of

error that might arise in their effort to estimate the population proportion who would

answer “yes” or “no” to this question? (Be sure to both identify any relevant types of

error with one of your vocabulary words and explain why it might occur.)

11.) Define the concept of “sampling error”. (Note: Your definition should include the idea

of sample, population, statistic, parameter.)

## Discussion Question_SNHU_Discrete Math 230

If you have access to the question bank, please use that to answer this. This is for MAT 230 at SNHU discussion. Please and Thank You.

A mathematical proof is an argument that convinces other people that something is true. In mathematical logic, “likely to be true” is not good enough. We try to prove things beyond any doubt at all.

In your initial post, address the following:

Compare proof by contradiction and proof by contrapositive and provide an example of one or the other.

## Boolean Circuits and Technology

Each assignment will allow you to learn how the topics of this course apply to the areas of computer science, Internet technology, or technology applications.

For this assignment, imagine that we are many years into the future and you have been hired by a technology company to create a human door key system. When a person steps on a special mat containing sensors that is located at his or her front door, these sensors grab information, send it through a set of circuits, and reach a one of two logical conclusions:

Yes (or 1), the person lives in this house and may enter.

No (or 0), this person does not live in this house and may not enter.

If the result is yes, the door automatically opens. If the result is no, you can decide what happens.

For this assignment, complete the following:

Define at least five features that can be sensed by the magic door mat such that each feature has a result of 0 or 1. This magical mat can sense anything, such as weight, height, eye color, hair color, gender, and so on. Because the result of the sensor can only be 0 or 1, you will have to think about how to do this. As an example, if the weight is greater than 125, the sensor returns a 1, else a 0. Similarly, if the hair color is NOT brown, the sensor returns a 0, else 1. These are just some ideas.

Explain each of your features clearly, including exactly what the 0 or 1 represents in each case.

Using at least five gates and at least five inputs, create a logical circuit that describes your system. This circuit will have at least five inputs, at least five gates, and one—and only one—output. Remember, the input values to and from the gates are only 0 or 1, but you can name them according to what they represent.

Create a logic table to show some examples of people who will and will not be able to enter. This table will be labeled with your attributes and will contain values of only 0 and 1.

Describe your circuit using a Boolean expression with proper use of AND, OR, and NOT symbols.

Describe what will happen to a person who cannot enter (that is, when the output of the circuit is 0). This is up to you, so feel free to be creative. Include at least one paragraph explaining your circuit, your features, and what will happen in cases where a person can or cannot enter the door. Hint: You can have the door inform the person that they cannot enter and why.

You may find it useful to read Chapter 11, pages 532–542, and look at the examples. You can combine attributes to make sure only the right person gets in. For example, if a person’s weight is greater than or equal to 125, you can have a 1. If the weight is less than 125, you can have a 0. Therefore, if the person weighs 250 pounds, this would result in a 1. You can use the circuit creatively with AND, OR, and NOT gates to grant or deny access using a set of measurable attributes.
