- One hundred students were asked whether they had taken courses in any of the three subjects, Mathematics, Computer Science and Information Technology. The results were given below. 45 had taken Mathematics; 18 had taken Mathematics and Computer Science; 38 had taken Computer Science; 21 had taken Information Technology; 9 had taken Mathematics and Information Technology.; 4 had taken Computer Science and Information Technology and 23 had taken no courses in any of the subjects. Draw a Venn diagram that will show the results of the survey.A derived attribute can be stored in a table or calculated on each occasion that it is required. An example of a derived attribute is your Grade Point Average which is calculated by adding together a score for each unit (e.g., HD=4, D=3, C=2, P=1, N=0) and dividing that by the number of units you have completed. Explain how the decision as to whether the Grade Point Average would be stored in a table or calculated would be made. You are administering a database in a large retail company that records sales at each of the company’s stores. Tuning the database to improve performance by adding indexes and optimising query execution is an important ongoing aspect of the physical database design. Which attributes in a database such as this (apart from the primary key) are likely to BENEFIT from being indexed? Which attributes would you generally avoid indexing, and why?In 2020, alumni collectively donated $11.37 billion to their colleges and universities, according to an annual report from the nonprofit Council for Aid to Education. That is an increase of 14.5 percent from the prior year, which the report attributes, at least in part, to a strong stock market. Some colleges and universities have a particularly high percentage of former students who make financial contributions. In that period, the 10 institutions with the highest percentages of undergraduate alumni donors boasted an average giving rate of 51.5 percent. Alumni donor count is used to calculate alumni participation by dividing it by the number of living alumni on record. For example, if your institution has 100,000 alumni of record (i.e., living with a good address) and 20,000 of them made a gift last year, your alumni participation rate is 20%. The importance of alumni participation cannot be understated; for example, U.S. News & World Report’s Best Colleges, the most prominent…

- For short listing of the candidates for a job in a company in different sections based on the cumulative percentage of the following fields. • I f cumulative percentage is more than 80% then hire in HR department. • If cumulative percentage is less than 80% and greater than 70% then hire in accounts department. • If cumulative percentage is less than 70% and greater than 60% then hire in sales department. • f cumulative percentage is less than 60% and greater than 50% then hire in helping staff. The cumulative percentage will be calculated as 60% of the marks obtained in test conducted by the company and 40% of obtained marks in interview. Total marks for the test and interview is 200 each. Write a computer program to construct a function with name "Selection to calculate the cumulative percentage and then display the message in which section the candidate is selected.Model evaluation Create a predictions variable using your fitted model and the test dataset; call it y_pred. Then get the accuracy score of your predictions and save it in a variable called accuracy. Finally get the confusion matrix for your predictions and save it in a variable called confusion_mat.

O 11:30pm O Midnight 10:30pm 12:30am OO 2 A Moving to another question will save this response.1) Holiday Inn hires you to examine three hotel locations that can each use some updating. They have $4 million available for the updates. The future revenue projected for each hotel is tied to how much renovation is done, according to the following table: Renovation Amount Future Revenue (in millions) (in millions) $0 $1 $2 $3 Hotel A Hotel B Hotel C $4 $7 $8 $9 $3 $6 $10 $12 $14 $3 $7 $8 $13 $4 $11 $15 Use dynamic programming to determine how to best allocate the $4 million in renovations between the three hotels (assume you can only use $1 million increments).Assume an attribute (feature) has a normal distribution in a dataset. Assume the standard deviation is S and the mean is M. Typically: Group of answer choices, multiple choice: Then the outliers usually lie below -3*M or above +3*M Then the outliers usually lie above -3*S or below +3*S Then the outliers usually lie below -3*S or above +3*S Then the outliers usually lie above -3*M or below +3*M
