Answer:
19.1 ft
Step-by-step explanation:
-This a Pythagorean theorem problem given by the function:
![b^2+h^2=H^2](https://tex.z-dn.net/?f=b%5E2%2Bh%5E2%3DH%5E2)
Where
H is the Hypotenuse length
h is the perpendicular height
b is the base length.
#Given that H=20 ft and base length,b =6 ft, the perpendicular height is calculated as:
![h^2+b^2=H^2\\\\h^2=H^2-b^2\\\\h^2=20^2-6^2=364\\\\h=\sqrt{364}\\\\=19.0788\approx 19.08\ ft](https://tex.z-dn.net/?f=h%5E2%2Bb%5E2%3DH%5E2%5C%5C%5C%5Ch%5E2%3DH%5E2-b%5E2%5C%5C%5C%5Ch%5E2%3D20%5E2-6%5E2%3D364%5C%5C%5C%5Ch%3D%5Csqrt%7B364%7D%5C%5C%5C%5C%3D19.0788%5Capprox%2019.08%5C%20ft)
![\approx 19.1 \ ft](https://tex.z-dn.net/?f=%5Capprox%2019.1%20%5C%20ft)
Hence, the ladder reaches the wall at a height of 19.1 ft

Letter F
Because:
1/5 = 2/10
and
1/2 = 5/10
2/10+5/10=7/10

Answer:
A standard devation of 15 means 68% of the norm group has scored between 85 (100 – 15) and 115 (100 + 15). In other words, 68% of the norm group has a score within one standard deviation of the average (100). Also, 95% of the norm group has an IQ score within two standard deviations of the average
