Answer 3

first add the numbers to find the total.
dividing this by the number of cars (6) will give the mean
Can you find the mean?

Answer 4

(1 + 1+ 2 + 2 + 2 + 4) / 6

Answer 5

2

Answer 6

yep
now to find the mean absolute deviation find the differences between each number and the mean (2) and then find their total.

Answer 7

2 - 1 =
2 - 1 =

and so on...

Answer 8

can you show me how to do that in numbers?

Answer 9

2 - 2 =
2 - 2 =
2 - 2 =
4 - 2 =

Answer 10

2?

Answer 11

the difference must be absolute values ( no negatives)

Answer 12

what is 2?

Answer 13

2-2= 0 and 4-2=2

Answer 14

right so we have 1 , 1 0,0,0 and 2 as the dirfferences
total of these is 4

so to get ur answer divide 4 by the t0tal of the numbers 6.

Answer 15

1.5?

Answer 16

4/6

then round to nearest tenth.

Answer 17

1?

Answer 18

Not 1.5 you divided 6 by 4
- its the reverse total of differences / 6 = 4 / 6

Answer 19

0.7

Answer 20
