Explanation:
The <em>guy-wire</em>, the highest point of the <em>cell phone tower</em>, and the the <em>point on the ground that is 25 ft from the base of the tower</em> form a right triangle, where:
- the <em>length of the guy-wire</em> is the hypotenuse of the triangle
- <em>the height of the cell phone tower </em>is one leg (75 ft)
- the distance from the <em>point on the ground to the base of the tower</em> is the other leg (25 ft).
Since you know the lengths of both legs, you can use Pythagora's theorem to find the hypotenuse (the lenght of the guy-wire):
![hypotenuse^2=(leg_1)^2+(leg_2)^2](https://tex.z-dn.net/?f=hypotenuse%5E2%3D%28leg_1%29%5E2%2B%28leg_2%29%5E2)
![hypotenuse^2=(75ft)^2+(25ft)^2](https://tex.z-dn.net/?f=hypotenuse%5E2%3D%2875ft%29%5E2%2B%2825ft%29%5E2)
![hypotenuse^2=5,625ft^2+625ft^2=6,250ft^2](https://tex.z-dn.net/?f=hypotenuse%5E2%3D5%2C625ft%5E2%2B625ft%5E2%3D6%2C250ft%5E2)
![hypotenuse=\sqrt{6,250ft^2}\approx 79.06ft\approx 79.1ft](https://tex.z-dn.net/?f=hypotenuse%3D%5Csqrt%7B6%2C250ft%5E2%7D%5Capprox%2079.06ft%5Capprox%2079.1ft)
Answer:
Mean= $ 1.96
Mode= No mode
Step-by-step explanation:
Mean is the value obtained by dividing the sum of all the observations by their numbers.
Mean is obtained by dividing the total number of the values with the number of values.
Mean= x1+ x2+ x3 + x4/ 4
Mean = $ 1.5 + $ 2.0 + $ 2.15 + $ 2.20/4= 7.85/4= 1.9625or 1.963 or $ 1.96
Mode is the most frequent occurring value in a data set. But since all the values in the given set occur only once the data does not have any mode .
There is no mode because every value has the same frequency, that is it occurs the same number of times.
5x+16= 2x+12+2x+14
Combine like terms
5x+16 = 4x+26
-4x -16 = -4x -16
1x =10
Divide by 1
X =10
Plug 10 in for x and solve to get answers!
To convert 115.9% to decimal divide by 100
115.9 ÷ 100 = 1.159
Answer: 1.159
