To calculate the average height of the students in the class, we first need to find the total height of all the students.
Total height of girls = 10 girls * 1.58m = 15.8m
Total height of boys = 20 boys * 1.67m = 33.4m
Total height of all students = 15.8m + 33.4m = 49.2m
Now, we need to find the total number of students in the class:
Total number of students = 10 girls + 20 boys = 30 students
Finally, we can calculate the average height of the students in the class by dividing the total height of all students by the total number of students:
Average height of students = 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
