Annette [7]3 years ago

Answer:

  Kathleen determines the four arithmetic means to be −2.8 , 1.4, 5.6, and 9.8.

Step-by-step explanation:

The overall interval is 14 -(-7) = 21 units in length. The four equally-spaced "means" divide the interval into 5 equal parts, each one of which is ...

  21/5 = 4.2

The four means are ...

  -7 +4.2 = -2.8

  -2.8 +4.2 = 1.4

  1.4 +4.2 = 5.6

  5.6 +4.2 = 9.8
