Find the coordinates of the midpoint of the segment whose endpoints are h(9, 10) and
k(7, 6).
find hk

  The coordinate of the midpoint is m ( 8   ,   8)     and the distance HK is 4.5

Step-by-step explanation:

To find the coordinates of the point of the segment whose endpoints are H(9,10) and K(7,6), we simply use this formula;

m( ,  )   =   m(     ,        )

 =  9        =  10            =   7             =   6

m( ,  )     =  m  (            ,           )

                       = m (         ,                      )

                          =m (  8   ,     8)

The coordinate of the midpoint is m (  8   ,     8)

To find the distance HK,

let D = distance HK

D  =   √    +    

       =  √(7 - 9)²   +   (6 - 10)²

       =  √(-2)²   + (-4)²

      =  √4  +  16

       =√20

      = 4.5  

The distance HK is 4.5

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

6e14 is the answer.
