You'll get two X values because there is a modulus.
First, lets transform the given vector into an unit vector (dividing by its module)
UnitVec = 4/5 i + 3/5 j
Then lets change this vector into a polar form
UnitVec = 1. with angle of 36.869 degrees taking as a reference the i vector
Then, the probem tells us that the vectors u and v make an angle of 45 degrees with UnitVec, so lets add+-45 to the vector in polar form
U = 1*[cos(36.869 +45)i + sin(36.869 +45)j] = 0.1414 i + 0.9899 j
V = 1*[cos(36.869 -45)i + sin(36.869 -45)j] = 0.9899 i - 0.1414 j
Answer:
x = 7
Step-by-step explanation:
All right triangles have at least 1 angle that is 90 degrees total. (It might be late for the answer sorry...)
Answer:
Step-by-step explanation:
Given
Represent the size with n and the probability with p
Required
Determine the expected value; E(x)
<em>Hence, the expected value is 7.86</em>
