The expression for the kinetic energy is mass times velocity squared over two
For the first question that gives us 2,25 joules
If the ball is at the given height then it has a further 60 Joules in potential energy.
Answer is D
Given:
The figure of a rhombus.
To find:
The value of x.
Solution:
We know that, if two lines intersect each other, then the vertically opposite angles are equal.
From the given figure it is clear that the diagonals intersect each other and construct two pairs of vertically opposite angles.
Since 
and 
are vertically opposite angles, therefore
Hence, the value of x is 95°.
You multiply the area of the triangle by 2
Answer:
That looks like interior angle to me
x = 47 (since interior angles are congruent)

If I understand what you are asking, you can use the median as an average since it is not affected by the mean ( median is a measure of center). Since a mean is affected by outliers, it might lower the score if there are very low outliers. But note that if there are outliers way <em>greater </em>it can increase the average. You can use the Inter Quartile Range if shown on a box plot ( measure of variability).
