brandon conducted a research to determine the preference of students during online classes. From the 250 students who participated in the study, 85 wanted to have synchronous classes, 90 wanted to have asynchronous classes, and 100 wanted to have blended learning. From the respondents, it was seen that 35 preferred either synchronous and asynchronous, 10 preferred synchronous and blended learning, 25 preferred blended learning and asynchronous, and exactly 55 liked two of the mode of learning.
1. How many students liked synchronous, asynchronous, and blended learning? 2. How many students liked synchronous learning, but did not preferred asynchronous or blended learning? 3. How many students did not like either of the three modes of learning? 4. Draw the initial and final Venn diagram.
A company studies the product preferences of 20,000 consumers. It was found that each of the
products A, B and C was liked by 7500, 6500 and 5500 respectively and all the products were
liked by 1230. Products A and B were liked by 2500, products A and C were liked by 2300 and
products B and C were liked by 2530. Prove that the study results are not correct
Suppose that the pairwise comparison method is used on the following preference table. If A, C, and E drop out, is the irrelevant alternatives criterion satisfied? Explain.
Choose the correct answer below.
O A. Yes. Candidate D wins the first election. If candidates A, C, and E drop out, candidate D still wins the second election.
O B. No. Candidate O wins the first election. If candidates A, C, and E drop out, candidate B wins the second election.
O C. Yes. Candidate B wins the first election. If candidates A, C, and E drop out, candidate B still wins the second election.
O D. No. Candidate B wins the first election. If candidates A, C, and E drop out, candidate D wins the second election.
