X - height of the tree.
A proportion is:
1/2 : x = 1 : 36
x = 36 * 1/2
x = 18
Answer. the tree is 18 feet tall.
Answer:
x = 10
Step-by-step explanation:
The line from the vertex to the base is a perpendicular bisector.
Consider the left side right triangle, eith base = x
Using Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
( x )² + 7² = ( )², that is
x² + 49 = 74 ( subtract 49 from both sides )
x² = 25 ( multiply both sides by 4 to clear the fraction )
x² = 100 ( take the square root of both sides )
x = = 10
The mean is the average, which is adding all the numbers up and dividing by how many numbers there are. There are 2x(1), 3x(2), 9(3), 9(4), and 5(5).
2+6+27+36+25 = 96.
There were 28 total.
Divide 96 by 28. 3.4 is the average.
The median is the middle number from least to greatest.
3.5 is the median.
