The circle: x = 4 y = 0.5
The square: x = 3.5 y = 1.5
The triangle: x = 0 y = 2.5
1, 3, 5 are functions because they pass the vertical line test
7 x 2 = 14
3 x 1 = 3
14+3 = 17
answer 17 unit^2
Ur outlier is 22....so we will remove it.
now we find the mean (average) of the data set...
(9+4+10+9+5+2+10+3+3+5) / 10 = 60/10 = 6...this is ur mean
now we subtract the mean from every data value...and find its absolute value
9 - 6 = 3....| 3| = 3
4 - 6 = -2...|-2| = 2
10 - 6 = 4..|4| = 4
9 - 6 = 3....|3| = 3
5 - 6 = -1..|-1| = 1
2 - 6 = -4...|-4| = 4
10 - 6 = 4..|4| = 4
3 - 6 = -3...|-3| = 3
3 - 6 = -3...|-3| = 3
5 - 6 = -1...|-1| = 1
now we find the mean (average) of these numbers...that is ur MAD
(3+2+4+3+1+4+4+3+3+1) / 10 = 28/10 = 2.8
ur answer : on average, the height of the plant varies 2.8 inches from the mean of 6 inches
