Answer:
D(-1,0)
Step-by-step explanation:
Plot points A(-3, 2), B(-1, 4), and C(1, 2) on the coordinate plane (see attached diagram).
Two sides AB and BC are of equal length and are perpendicular, because
If the quadrilateral ABCD has all sides perpendicular, then ABCD is a square. The diagonals of the square bisects each other. Find the coordinates of the point of intersection of these diagonals. This is the midpoint of segment AC:
If point O(-1,2) is the point of intersection of diagonals, then it is the midpoint of the diagonal BD. Find coordinates of point D:
Thus, D(-1,0)
Answer:
Option D is correct
Step-by-step explanation:
When a cube with sides numbered 1 through 6 is rolled one time, the possible events are six i.e. getting {1,2,3,4,5,6} , with equal probability for each.
Of these, the events for which we get 4 or greater are {4,5,6} i.e. three events.
Hence probability of getting 4 or greater is
