What is the mean absolute deviation for 2, 9, 1, 7, 8, and 9? 1 3 6 8

It's 3

Step-by-step explanation:

got it right on my test ;)

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
