Kathleen correctly determines four arithmetic means between −7 and 14. What values does Kathleen determine?
Annette [7]

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

In a volleyball game, Caroline served the ball over the net 16 out of 20 times. What percent did she not make her serve over the
brilliants [131]

16/20. We reduce that and get 4/5.

After this it's much simpler to chage it.

100 dividied by 5 is 20. (20,40,60,80,100)

So the 4th number (4/100)

is 80. 80%.

20% she didn't and 80% she did :) (100-80)
