The smallest bone in the human body is the stapes bone it is located in the ear and is about 2.8 millimeters in length. Write this number in expanded form

2+.8

Step-by-step explanation:

You have 2 millimeters and .8 of a millimeter so you add them up.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

it is not that hard all u have to do is plot the graph
