Answer:

<em><u>1.6</u></em>

Step-by-step explanation:

The Mean Absolute Deviation (MAD) is the distance each number is away from the mean divided by the amount of numbers.

15 is 4 away from 19, for example

So:

19 - 15 = 4

25 - 19 = 6

19 - 13 = 6

19 - 15 = 4

19 - 18 = 1

20 - 19 = 1

22 - 19 = 3

24 - 19 = 5

4 + 6 + 6 + 4 + 1 + 1 + 3 + 5 = 30

30/19 = 1.5789, rounded to 1.6

Help with this question, please!! I don't understand!
kondor19780726 [428]

Answer:

FE = 30°

Step-by-step explanation:

arc FGC = arc FG + arc GB + arc BC

220° = 90° + arc GB + 70° . . substitute known values

60° = arc GB . . . . . . . . . . . . . subtract 160°

__

External angle A is half the difference of arcs EG and GB:

30° = (1/2)(arc FE +90° -60°) . . . substitute known values

60° = arc FE + 30° . . . . . . . . . . . multiply by 2 and simplify

30° = arc FE . . . . . . subtract 30°

_____

The key to this problem is the relationship between external angle A and the measures of the arcs it subtends.

Can I please have some help????
DedPeter [7]

Answer:

avn= -8 + (n-1)(-7)

Step-by-step explanation:

arithmetic sequence formula= avn= av1 + (n-1)d

av1= first number in the sequence

d= common difference

n= the number of the term to find

The common difference is -7 so d=-7 and you plug it into the equation. The first number in the sequence is -8 so av1.

There is no specific n to find so it remains n.

I hope this helps! Let me know if this helps.
