Answer:

Step-by-step explanation:
If air resistance is neglected, the energy is constant. That means that in every point in the trajectory the energy is the same.
At the point of height h, all the energy is potential and velocity is zero (no kinetic energy)

At point of height h/4, some of the potential energy has transformed in kinetic energy and the velocity is no longer zero. But we know the total amount of energy is the same as the maximum height point.
With that information, we can calculate the velocity v:

3x - 6y = 20
-6y = -3x + 20
y = 1/2x - 20/6.....slope = 1/2...y int = -20/6 = -10/3
2x - 4y = 3
-4y = -2x + 3
y = 1/2x - 3/4..slope = 1/2...y int = -3/4
same slope, different y int = parallel lines = no solution = inconsistent
58% is the answer. 7 dividing 12= 0.5833333
you much move the decimal over two places and you would get 58%
Answer:
Option B.
Step-by-step explanation:
The non-uniform probability is when the event is not same in the occurring of event.
Option A is uniform because there will be equal chance of getting head or tail.
Option B is non-uniform because sum can be any number if we get(3,4) it will be 7 and if we have (2,3) then it will be 5.
Option C is uniform because we have equal number of red and green balls so, selecting a ball from both will be same.
Option D is uniform because chance of 1,2,,3,4,5 or 6 will be equal chance from rolling a die that is 1/6 in all cases.
Therefore, Option B is correct
