Answer:
AB = 60 cm
Step-by-step explanation:
AB + BC = AC
let the length of BC = x then AB = 4x, hence
4x + x = 75
5x = 75 ( divide both sides by 5 )
x = 15
AB = 4x = 4 × 15 = 60 cm
Answer:
--- Mean absolute deviation of educational documentary
--- Mean absolute deviation of prime time drama
Step-by-step explanation:
Given
See attachment for table
Required
Determine the mean absolute deviation of each
Mean absolute deviation m(x) is calculated as:
For Educational Documentary
First, calculate the mean
So:
The mean absolute deviation is then calculated as:
For Prime time Drama
First, calculate the mean
So:
The mean absolute deviation is then calculated as:
Answer:
A = 2 pi R^2 + 2 pi R h total surface area
R^2 = 48 2 pi R = 8 * 6^1.2 given
56 pi 6^1/2 - 2 pi R^2 = 2 pi R h f rom first formula
28 * 6^1/2 / R - R = h divide by 2 pi r
28 * 6^1/2 / R = 28 * 6^1/2 / (4 3^1/2) = 7 * 2^1/2
h = 7 * 2^1/2 - 4 * 3^1/2
