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
The given lines are perpendicular
Step-by-step explanation:
if Two lines are perpendicular then their slopes are
m
Where m₁ is slope of first line and m₂ is the slope of second line.
Since the lines are in slope-point form the standard form is:
where m is the slope
The slope of first line y= -9/5x + 1/5 is: m₁ = -9/5
The slope of second line y= 5/9x + 2/9 is: m₂= 5/9
So, m i.e
So, The given lines are perpendicular
