Given
P
(
A
)
=
0.36
P(A)=0.36,
P
(
B
)
=
0.2
P(B)=0.2 and
P
(
A
∩
B
)
=
0.122
P(A∩B)=0.122, find the value of
P
(
A
∪
B
)
P(A∪B), rounding to the nearest thousandth, if necessary.

the answer

b. they are parallel and will never intersect.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
