If the numbers in the right column represent times, pp:qq is equivalent to pp+(qq/60). Your scatter plot would use the values
... (2011, 1.927), (2012, 1.930), (2013, 1.914), (2014, 2.001)
1. See attached for the scatter plot
2. The data points have a generally upward trend, so the correlation is positive.
3. Because the correlation is positive, the line of best fit will have a positive rate of change (slope).
For A you should put -3 and for b put 2
A full circle = 360 degrees.
DOC + COB + DEB = full circle = 360
44 + 80 + DEB = 360
124 + DEB = 360
DEB = 360 - 124
DEB = 236 degrees
The answer is 16. equilateral triangle all sides are equal length, so just divide the primeter by 3, the number of sides in a triangle
