Use 4 steps of the Modified Euler’s method to solve the following differential equation to t = 2.6, given that y(0) = 1.1. In your working section, you must provide full working for the first two steps. To make calculations easier, round the calculations at each step to four decimal places, and provide your final answer with four decimal places. dy/ dt = 1.4sin(ty)

Scenario

You are a defense attorney and an eyewitness to the crime in question has given testimony identifying your client as the culprit. Given what you know about effortful vs. automatic encoding, state-dependent and mood-congruent memory, interference, and the constructive nature of memory (including misinformation, imagination, and source amnesia effects), how would you challenge the validity and reliability of that eyewitness testimony? What arguments would you use to confront the witness in your cross-examination?

Step 1:. Read ONE of the following four research articles and summarize the article's predictions(hypotheses), methods, and findings.

Step 2:  Answer the questions in the Scenario above. Use the research article you've chosen, as well as material from the rest of this lesson, to support your conclusions.

Your brief summary and evaluation of the reliability of eyewitness testimony (integrating the above-mentioned issues) should be 2-3 pages (double-spaced, 1-inch margins, 12-point font). See the "More About the Eyewitness Identification Assignment" page and the "Eyewitness Identification APA Checklist" for more resources and information. Submit your write-up in the "Major Assignment - Eyewitness Identification" Assignment Tool.

A – Using the IS-LM curves explain in detail and show a) how and why the drop in housing prices caused a major financial crisis in 2008, then how the 2008 financial crisis transformed into a major economic crisis and crashed the economy. b) What would have happened if FED employed a set of monetary policies opposite of those we saw during the recession. Discuss their impact on the economy, output, interest rates, and consumption and investment expenditures. c) What would have happened if the government employed a set of fiscal policies opposite of what the government did during the recession. Discuss their impact on the economy, output, interest rates, and consumption and investment expenditures. Begin with an IS-LM diagram showing the situation of the economy prior to the crisis in 2008, then add new curves for each questions (a, b, and c). Be specific in explaining the monetary and fiscal policies asked in the questions which are opposite of those introduced by the FED and government between 2008-2010 (TARP, American Recovery and Reinvestment Ac)t.

OPEC is an example of a cartel. Explain and depict in detail, how the price and quantities are determined in the cartel market for cartel members and other companies! Denote clearly all curves, prices and quantities!

As per child care, You are about to set up a small business in the community services sector. Consider the organisation’s objectives and write a 3 page paper outlining the professional and ethical standards to which your organisation would adhere. Use your imagination to fill any gaps. What external influences and data would inform the expectations you might have of your employees? Explain how you would ensure that the employees working in the organisation continuously upgrade their skills and how you would determine the developmental needs of your employees. How would you encourage employees to reflect upon their work practice, evaluate their own skills and learning needs and improve the organisation’s professional practice?

a) Your initial belief about stock A is that its future price cannot be predicted on the basis of existing public information. An insider comes forward claiming that the price will fall. You know the insider is not totally reliable and tells the truth with probability p=0.3. Use Bayes’ theorem to calculate the posterior probability that the stock price will fall, based on the insider’s evidence.A second insider, equally unreliable, comes forward and also claims that the price will fall. Assuming that the insiders are not colluding, what is your posterior probability of a price fall?  Based on your above answers, does the probability of future stock price depend on unreliable insiders? Would you expect this outcome? Explain your argument.

A description of workers. Each year, the Census Bureau selects a different and random sample of more than 3 million of households to be interviewed in American Community Survey (ACS). The dataset that have been assigned to you contains infor mation of a small random sample of workers of a particular state interviewed in the ACS 2016. I

Notes In your answers use up to one decimal place when the number is not an integer If the number is close to zero (i.e 0.0006) use up to four decimal places e Show your work to get full credit. When it corresponds, indicate what statistic unction of Excel you used to compute the estimate. Use the dataset that was assigned. If you use a different dataset, your homework will not be graded

(a) Describe the structure of the data set. In your answer include the population egorical (nominal/ordinal) or quantitative (discrete ,continuous), type of data (1.e., cross of interest, sample size, number of variables, type of variables (i.e. cat sectional, time series, or longitudinal data). (10 points)

(b) If each year the Census Bureau inter viewed the same sample of households, what would be the type of dataset generated by the ACS in this case? (3 pts). Explain.

(c) Use the earnings (WAGP) of the first ten workers to calculate the Σ and (-) (i.e. the sum of the squared deviations) of the workers earnings. Use to compute the sample mean and the sample standard deviation of these sums these workers' earnings. (10 pts)

Think about your place of work, your household or your school. Then, come up with 2 examples of efficiency (i.e, what you/they do well) and explain why you consider it efficient, AND 2 examples of inefficiency (i.e, what you/they do NOT do as well as you are capable of) and explain why it is inefficient. For the inefficiency, explain how you would solve each of those problems (correct the inefficiencies). When you reply to others, offer suggestions, input and advice - maybe you experienced something similar.
