For each probability density function, over the given interval, find E ( x ) , E ( x 2 ) , the mean, the variance, and the standard deviation. f ( x ) = 1 8 x , [ 0 , 4 ]
For each probability density function, over the given interval, find E ( x ) , E ( x 2 ) , the mean, the variance, and the standard deviation. f ( x ) = 1 8 x , [ 0 , 4 ]
Solution Summary: The author calculates the probability density function f(x)=18x over the interval [0,4].
Find the (exact) direction cosines and (rounded to 1 decimal place) direction angles of = (3,7,6)
Let a = (-1, -2, -3) and 6 = (-4, 0, 1).
Find the component of b onto a.
Forces of 9 pounds and 15 pounds act on each other with an angle of 72°.
The magnitude of the resultant force
The resultant force has an angle of
pounds.
* with the 9 pound force.
The resultant force has an angle of
with the 15 pound force.
It is best to calculate each angle separately and check by seeing if they add to 72°.
