The centroid of a triangle |
2006-01-18 |
|
Andrea pose la question :
I am trying to find the centriod of a triangle. I have been given the three vertices of the triangle: A (-25, -20), B (-5, -40), and C (15, 30). I believe I calculated the correct midpoints: AB(E) (-5, 5), BC(D) (5, -5), and AC(F) (-15, -30). When I graphed these points I came up with the solution (-5, -10), but I can't seem to write the answer out (equations of the lines, etc) correctly. Any help would be greatly appreciated!

The mean house price |
2003-09-10 |
|
Carol pose la question :
Question:
I have to find the mean from the following example: | Price Range £000 | No of Houses | | 55 and under 60 | 3 | | 60 and under 65 | 6 | | 65 and under 70 | 13 | | 70 and under 80 | 21 | | 80 and under 100 | 15 | | 100 and under 130 | 7 | | 130 upwards | 1 | I know when calculating the mean you use the mid points of the classes, but how does this work for the 130 upwards class? Also, does this still work given the difference in the classes (ie. 1st class is 5, 5th class is 20, etc). Any help to get me started would be greatly appreciated.
