In a Mathematics class with 30 students, the teacher wants 2 different students to present the solutions to problems 3 and 5 on the board. In how many ways can the teacher assign problems? In a survey, 10 characteristics of a teacher are listed. You are asked to indicate in order of importance which 4 of these characteristics make a good teacher How many possible responses are there? What will be slope 'a' of the regression line Y = ax + b if coefficient of correlation r is 0.5, Sx = 6 and Sy = 9 ? A population consists of four observations: {1,3, 5,7}. What is the variance? Verify your selected option.
A teacher's ideology influences his or her teaching in several ways. The method that is used will be affected as well as the way that the teacher interacts with the students.
Since there are 5 different prizes, and assuming a pupil can get only one prize the answer is25P5 = 6,375,600 ways.
For this type of problem, order doesn't matter in which you select the number of people out of the certain group. We use combination to solve the problem.Some notes to know what is going on with this problem:• You want to form a committee of 2 teachers and 5 students to be formed from 7 teachers and 25 students • Then, you select 2 teachers out of 7 without repetition and without considering about the orders of the teachers.• Similarly, you select 5 students out out 25 without repetition and without considering about the orders of the students.Therefore, the solution is (25 choose 5)(7 choose 2) ways, which is equivalent to 1115730 ways to form such committee!
