It's more efficient to hold a random drawing because the probability is higher.
For every 2 person, 1 person gets to go to the concert.
Answer is 1/2 aka 0.5 aka 50%
Hope this helps. - M
The answer is
C
Explaintion:
Plugging 3 into x will give you 36 and 36-37 equals -1 and since y=-1 that’s means that is your answer
Given:
cos 120°
To find:
The exact value of cos 120° in simplest form with a rational denominator.
Solution:
We have,
It can be written as
![[\because \cos (90^\circ-\theta)=-\sin \theta]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Ccos%20%2890%5E%5Ccirc-%5Ctheta%29%3D-%5Csin%20%5Ctheta%5D)
![[\because \sin 30^\circ=\dfrac{1}{2}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csin%2030%5E%5Ccirc%3D%5Cdfrac%7B1%7D%7B2%7D%5D)
Therefore, the exact value of cos 120° is 
.
The answer would be D. (11,14),(8,18)
To find the answer you need to find an equal slope.
To find the slope you need to do y2-y1/x2-x1
Y2 is 18, y1 is 13, x2 is 8, and x1 is 11
18-13/8-11
