Answer:
22'
Step-by-step explanation:
25^2=15^2+x^2 where x=tree height less the 2' from the top
x=20'
Add the 2' from wire connection to top of tree.
22'

Answer:
![\bar X -2s = 27.12- (2*1.13) =24.86](https://tex.z-dn.net/?f=%20%5Cbar%20X%20-2s%20%3D%2027.12-%20%282%2A1.13%29%20%3D24.86)
![\bar X +2s = 27.12+(2*1.13) =29.38](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%2B2s%20%3D%2027.12%2B%282%2A1.13%29%20%3D29.38)
So if a value is less than 24.86 would be considered significantly low and a value higher than 29.38 would be considered as significantly high.
The value for the analysis is 29.8 and as we can see 29.8>29.38 so then we can consider 29.8 as a value significantly high.
Step-by-step explanation:
For this case we have the mean given
and the deviation ![s= 1.13](https://tex.z-dn.net/?f=%20s%3D%201.13)
The Range Rule of Thumb says "that the range is about four times the standard deviation"
So then we will ave approximately most of the value within 2 deviations from the mean, so we can find the limits considered normally like this:
![\bar X -2s = 27.12- (2*1.13) =24.86](https://tex.z-dn.net/?f=%20%5Cbar%20X%20-2s%20%3D%2027.12-%20%282%2A1.13%29%20%3D24.86)
![\bar X +2s = 27.12+(2*1.13) =29.38](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%2B2s%20%3D%2027.12%2B%282%2A1.13%29%20%3D29.38)
So if a value is less than 24.86 would be considered significantly low and a value higher than 29.38 would be considered as significantly high.
The value for the analysis is 29.8 and as we can see 29.8>29.38 so then we can consider 29.8 as a value significantly high.
Answer:
y = ⅗x
Step-by-step explanation:
The line passes through the point of origin, (0, 0). This implies that the graph represents a proportional relationship between x and y. Thus, in slope-intercept form, the line of a proportional graph can be represented as y = mx.
Where,
m = slope/constant of proportionality = y/x
To write an equation for the line, let's find the slope using any of the points on the line.
Using (50, 30):
Slope (m) = 30/50 = ⅗
Plug in the value of m into y = mx
Thus, equation of the line would be:
y = ⅗x
