In a laboratory setting, scientists are testing the claim that a certain contagious disease spreads at a rate that is proportional to the number of interactions between those that are infected x(t...
Let P(t) represent the number of people who, at time t, are infected with a certain disease. Let N denote the total number of people in the population. Assume that the spread of the disease can be modeled by the initial value problem: dP/dt = k(N − P)P, P(0) = P0. At time t = 0, when 100,000 member of a population of 500,000 are known to be infected, medical authorities intervene with medical treatment. As a consequence of this...
2. Two differential equations modeling problems follow. Do at least one of them (a) i. If N is the (fixed, constant) population in among residents can often be modeled as follows: Let x = x(t) be the number of people who have heard caught the disease by time t days. Then the disease spreads via the interactions between those who have the disease, and those who don't. The rate of transmission of the disease is thus proportional to the product...
I need help with question 30d 16. y = 0 (that is, y(x) = 0 for all x, also written y(x) = 0) is a solution of (2) (not of (1) if (x) • o , called the trivial solution 17. The sum of a solution of (1) and a solution of (2) is a solution of (1). 18. The difference of two solutions of (1) is a solution of (2). 19. If yı is a solution of (1), what...
Please read the article bellow and discuss the shift in the company's approach to genetic analysis. Please also discuss what you think about personal genomic companies' approaches to research. Feel free to compare 23andMe's polices on research with another company's. Did you think the FDA was right in prohibiting 23andMe from providing health information? These are some sample talking points to get you thinking about the ethics of genetic research in the context of Big Data. You don't have to...
First, read the article on "The Delphi Method for Graduate Research." ------ Article is posted below Include each of the following in your answer (if applicable – explain in a paragraph) Research problem: what do you want to solve using Delphi? Sample: who will participate and why? (answer in 5 -10 sentences) Round one questionnaire: include 5 hypothetical questions you would like to ask Discuss: what are possible outcomes of the findings from your study? Hint: this is the conclusion....
