The average height of 4 children is (15h-3). two more children join the group with heights of (10h+46) centimeters and (14h-16) centimeters. find the average height of the 6 children if h=9

123.5 centimeters

Step-by-step explanation:

Let sum of observations be S and number of observations be n.

Average A=

The average height of 4 children is (15h-3)

Also, when two more children join the group with heights of (10h+46) centimeters and (14h-16) centimeters the sum of heights of 6 children will be

Now, Average height of 6 students=

At h=9

Average height of 6 students=

horizontal translation of 2 units in the positive x direction

followed by

vertical translation of 3 units in the positive y direction

the square root of what number? if you add that, then someone will probably answer the question.
