3/12, or 1/4, are defective.
he tests 4/12, or 1/3, fuses.
1/4(1/3) = 1/12 ?
i’m sorry if this is wrong. i’m not good at probability!
Answer:
idk sorry
Step-by-step explanation:
By definition, the unit vector of v = (a,b) is

Therefore,
The unit vector of v₁ = (3,5) in the direction of |v₁| s
(3,5)/√[3² + 5²]
= (3,5)/√34
The unit vector of v₂ in the direction of |v₂| is
(-4,7)/√[(-4)² + 7²]
= (-4,7)/√65
Answer:
The unit vector of v₁ in the direction of |v₁} is

The unit vector of v₂ in the directin of |v₂| is
