Step-by-step explanation:
The sum is formed by adding corresponding elements. For example, the lower right element (row 3, col 3) of the sum is 5+4 = 9
(-1, 3)
this is because in a coordinate plane, using the coordinates you gave it is the missing vertice is (-1,3)
3/7= 0.428571
3/6= 0.5
3/5= 0.6
So 3/5 is the greatest of all of them.
The average value over the interval is the area under the curve divided by the width of the interval.
Area = 4*(6 -1) +5(8 -6) = 30
Width = 8 - 1 = 7
Average value = 30/7 = 4 2/7
No, it is not possible. The total measure of all angles in a triangle must be 180. If you add these three together, you get 190.
