Total children: 6

Meh :/
Total, um, average height of 6 children: 1.65+1.35= 3
3.00 divided by 6
0.50
There we go :)

To find the average height of the 3 boys and 3 girls, you need to consider the total height of all 6 individuals.

1. Begin by finding the total height of the 3 boys and 2 girls. To do this, multiply the average height by the number of individuals:

Total height of 3 boys and 2 girls = Average height (1.65m) x Number of individuals (5)

Total height of 3 boys and 2 girls = 1.65m x 5 = 8.25m

2. Now, calculate the total height of all 6 individuals by adding the height of the additional girl (1.35m):

Total height of 3 boys and 3 girls = Total height of 3 boys and 2 girls + Height of additional girl

Total height of 3 boys and 3 girls = 8.25m + 1.35m = 9.60m

3. Finally, compute the average height by dividing the total height by the number of individuals:

Average height of 3 boys and 3 girls = Total height of 3 boys and 3 girls / Number of individuals (6)

Average height of 3 boys and 3 girls = 9.60m / 6 = 1.60m

Therefore, the average height of the 3 boys and 3 girls is 1.60 meters.

total height of first 5 students = 5(1.65)

Add the new girl's height and take the average of the 6 students.
