The sum of two vectors is (- 0.5, 10.1)
<u>Explanation:</u>
To add two vectors, add the corresponding components.
Let u =⟨u1,u2⟩ and v =⟨v1,v2⟩ be two vectors.
Then, the sum of u and v is the vector
u +v =⟨u1+v1, u2+v2⟩
(b)
Two vectors = ( 3, 4 )
angle 2π/3 = 120°
In x axis, the vector is = 7 cos 120°

In y axis, the vector is = 7 sin 120°
= 7 X 0.866
= 6.062
The second vectors are ( -3.5, 6.062)
Sum of two vectors = [( 3 + (-3.5) ), (4 + 6.062)]
= (- 0.5, 10.1)
Answer:
x = 83 degrees
Step-by-step explanation:
35 + 28 = 63
63 + 34 = 97
180 - 97 = 83
Answer:
your answer is going to be 2170
Step-by-step explanation:
Answer:
The 0 and 1 outcomes would be considered unusual.
Step-by-step explanation:
We can define as usual outcomes, the ones that fall between
.
According to a binomial distribution, s value is

The expected value out of a 8 people sample is

Then, our interval of usual values lies between

We can conclude that 0 and 1 (the results that lie outside of the interval) are unusual.
Step-by-step explanation:
you solve by using sqaure roots. hope this helps
