Answer:
m= -3
Step-by-step explanation:
You should do m = -1 - 2 x 1 - 0 which equals m = -3
Step-by-step explanation:
x²+y²−8x−2y=48
the radius => √[(8/2)² + (2/2)² +48] =
√(16+1+48) =√65
the center => (8/2, 2/2)
=> (4, 1)
Answer: b
Step-by-step explanation:
If:
![\frac{Boys}{20} = 0.45](https://tex.z-dn.net/?f=%20%5Cfrac%7BBoys%7D%7B20%7D%20%3D%200.45)
Soon:
![\frac{Boys}{20} = 0.45 \to Boys = 20*0.45 \to \boxed{Boys = 9}](https://tex.z-dn.net/?f=%5Cfrac%7BBoys%7D%7B20%7D%20%3D%200.45%20%5Cto%20Boys%20%3D%2020%2A0.45%20%5Cto%20%5Cboxed%7BBoys%20%3D%209%7D)
Therefore: (<span>It's not a boy)
</span>Students = 20
Boys = 9
girls = ?
![Girls + Boys = Students](https://tex.z-dn.net/?f=Girls%20%2B%20Boys%20%3D%20Students)
![Girls + 9 = 20](https://tex.z-dn.net/?f=Girls%20%2B%209%20%3D%2020)
![Girls = 20 - 9](https://tex.z-dn.net/?f=Girls%20%3D%2020%20-%209)
![\boxed{Girls = 11}](https://tex.z-dn.net/?f=%5Cboxed%7BGirls%20%3D%2011%7D)
Answer: (Describe the likelihood of not choosing a boy)
