Final answer:
To find the percentage of students who like the course, divide the number of students who like the course (34) by the total number of students (42), and then multiply by 100%. The result is approximately 81%, making option (c) the correct answer.
Step-by-step explanation:
To calculate the percentage of students who like the course, you can use the formula:
Percentage = (Number of likes / Total number of students) × 100%
In this case, the total number of students is the sum of those who like and those who dislike the course, which is 34 who like plus 8 who dislike, giving us a total of 42 students.
Applying the formula:
Percentage of students who like the course = (34 / 42) × 100%
First, we divide 34 by 42, which equals approximately 0.8095. Then we multiply 0.8095 by 100% to convert it into a percentage.
Therefore, the percentage is:
0.8095 × 100% = 80.95%
Rounding to the nearest whole number gives us 81%. Therefore, the correct answer to the question is (c) 81%.
