Assignment A scientist has developed a mathematical model for a physical process, and he wants to check how good is model is. To evaluate the correctness of his model, he wants to test the results of his model under certain parameters and compare them with experimental results. Write a program that first reads the number of tests (testCount) as an int followed by the results of each test according to the model as a double array (testModel) and finally the results of each test according to experiments as a double array (testExperiment). Then, the program should calculate the error of the model by evaluating the average of the ratio of absolute values (i.e., mutlak değer) of the differences between the model result and experimental result to the model result (see formula below) using a function. testCount testModel, - textExperiment, testModel, Error= Input testCount NOTE: Individual ratio of absolute value of the difference between the model value and the experiment value to the model…
What's Hiding Amongst the Crowd? Language - Java Script A word is on the loose and now has tried to hide amongst a crowd of tall letters! Help write a function to detect what the word is, knowing the following rules: The wanted word is in lowercase. The crowd of letters is all in uppercase. Note that the word will be spread out amongst the random letters, but their letters remain in the same order. ● Examples detectWord("UcUNFYGaFYFYGtNUH") → "cat" detectWord("bEEFGBuFBRrHgUHINFYaYr") → "burglar" detectWord("YFem HUFBbezFBYZF BYLleGBYEFGBMENTment") → "embezzlement"

The below cod is the code that it’s mentioned in the question. Write your cod and show it in a picture, please.
The programming language is - Python a. Write a function called daysOver that takes three arguments: a dictionary, a location (such as ‘Sydney’, ‘Adelaide’,etc) and a temperature and returns the number of days that were over the given temperature for the given location. For example, if we call the function using the line: total = daysOver(dictionaryData, ‘Adelaide’, 40) total will hold the number of days that Adelaide had a temperature greater than 40 celsius in the data. As a test, there were 54 days over 40 celsius in the data. Check that total is 54 for the example when you run your code. b. Use the daysOver function to print the number of days over 35 celsius for each of the following cities: 'Adelaide','Perth','Melbourne','Canberra','Sydney','Brisbane','Darwin' c. Which of the Australian cities has the most number of days over 35 celsius? My spreadsheet looks like this Since I cannot attach an excel file, my excel file name is "weatherAUS.csv"
a) Write a program that asks user to enter number of vertices in an undirected graph and then the adjacency matrix representing the undirected graph. The program, then, must display whether the given graph is connected or not. You will find two sample runs of the program below. Sample 1 Sample 2 Enter number of vertices: 3 Enter number of vertices: 3 Enter adjacency matrix: 0 1 1 1 0 0 1 0 0 Enter adjacency matrix: 0 1 0 1 0 0 0 0 0 The graph is connected. The graph is not connected.
