To calculate the average height of the students in the class, we first need to find the total height of all the students combined and then divide by the total number of students.
Total height of the girls = 10 girls x 1.58m = 15.8m
Total height of the boys = 20 boys x 1.67m = 33.4m
Total height of all students = 15.8m (girls) + 33.4m (boys) = 49.2m
Total number of students in the class = 10 girls + 20 boys = 30 students
Average height of the students in the class = Total height of all students / Total number of students
Average height = 49.2m / 30 = 1.64m
Therefore, the average height of the students in the class is 1.64m.
A class contains 10 girls and 20 boys. The average height of the girls is 1.58m and the average height of the boys is 1.67m . Calculate the average height of the students in the class
