No because mixed numbers need atleast a one and a fraction to be a mixed number
1) Coordinates of A: (-1,5) Coordinates of C: (6,-9)
2) Coordinates of A: (-1,-14) Coordinates of M: (6,7)
C = sin⁻¹ (sin(B) * c / b) = sin⁻¹ (sin [90degrees] * 6 / 12.00) = 30 degrees
The standard error of the mean is the standard deviation which is 6.50
