Ok so find the median so put the numbers in order so 82,83,84,85,85,86,86,86,87,87,88,89,90 then start from both sides cross off from both dies at the same time 83,84,85,85,86,86,86,87,87,88,89
84,85,85,86,86,86,87,87,88
85,85,86,86,86,87,87
85,86,86,86,87
85,86,86,86
86,86
so... 86 is the answer. i know its long but its the whole work hope it helped.
In this case, we have that there is a relationship between width and height, which is 16: 9, which means that any screen that has the same ratio would be an identical screen.
How would we do this? it must either be raised to a power or rationalized on both sides of the ratio.
If we raise to a power, it would give very large dimensions for an HDTV, therefore, it is best to remove the square root on both sides, since it has more common values for a TV.
4: 3
Therefore, a 4: 3 screen is a good choice for an HDTV with the same ratio.
Imagine or construct a right triangle with the 46 ft leg lying on the ground. This is the "adjacent side" of the triangle; it lies immediately adjacent to the 68 degree angle. The side opposite this angle is h, the height of the tree.
The tangent function includes angle, opp side and adj side:
tan 68 degrees = opp / adj = h / (46 ft), and so:
(46 ft)*tan (68 degrees) = opp = h
Then the height of the tree is h = (46 ft)(2.47) = 114 ft
