Y = mx + b
m = (y2 - y1)/(x2 - x1)
y = (26,600 - 18100)/(20 - 10)x + b
y = 850x + b
18100 = 850(10) + b
b = 9600
R(x) = 850x + 9600
A^2 + b^2 = c^2
324 + 6400 = c^2
6,724 = c^2
c = 82
82 cm.
The mean is 73.44<span>
</span>You could've found this by adding up all the values in the data set, then dividing by how many numbers were in the data set!
66+81+60+72+79+83+60+92+68 = 661
661 ÷ 9 = 73.44
