The midpoint of overline AB is M(7,-7) . If the coordinates of A are (8, - 6) , what are the coordinates of B?

Measure the distance between the two end points, and divide the result by 2. This distance from either end is the midpoint of that line. Alternatively, add the two x coordinates of the endpoints and divide by 2. Do the same for the y coordinates.

The average height of 4 children is (15h-3). Two more children join the group with heights of (10h+46) centimeters and (14h-16)

oksian1 [2.3K]

Answer: 123.5 centimeters

Step-by-step explanation:

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

Average A= $\frac{\text{S}}{\text{n}}$

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

$(15h-3)=\frac{S}{4}\\\Rightarrow\ S=4(15h-3)\\\Rightarrow\ S=60h-45$

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

$S+(10h+46)+(14h-16)=60h-45+10h+46+14h-16=84h-107$
