Answer:
Step-by-step explanation:
given are two vectors
a) A+B = sum of twovectors = simply adding corrsponding compnents
=
Magnitude of the above vector =
Direction is making an angle of arc tan (-3) with x axis
b) A-B = Difference
=
Magnitude of difference vector =
Direction is making an angle of arctan (1/2) with positive x axis.
(angle = arctan (jcomponent/icomponent)
Answer:
Following are the solution to the given points:
Step-by-step explanation:
For point (a)
:
In this, two points are exclusive to one another, it is a probability that first or the second project will have breaches,
Since the p(A & B)=0 is mutually exclusive.
For point (b):
For point (c):
if both a and b are independent:
(a):
(b):
angle a + angle b + angle c = 180° (angle sum property of triangle)
110°+35°+angle c=180°
165°+ angle c = 180°
angle c = 180°-165°
angle c = 15°
