Answer:
2
Step-by-step explanation:
the reason is because 2/3 of the sutudents in hannas homeroom plan to do some volentering. and of thoses studants 2 of them are going to volenteer insted of 3 that is why your answer ig going to be 2
If it’s volume it’s just L x W x H which is 18 x 10 x 2 which is 360cm^3
Answer:
Step-by-step explanation:
Given
17 % of the drivers stopped have invalid licenses
n=24 drivers are stopped
using Binomial distribution
![^nC_r(p)^r(q)^{n-r}](https://tex.z-dn.net/?f=%5EnC_r%28p%29%5Er%28q%29%5E%7Bn-r%7D)
here p=0.17
q=1-0.17=0.83
(a)none will have valid license i.e. r=0
![P(r=0)^{24}C_0(0.17)^0(0.83)^{24}=(0.83)^{24}=0.0114](https://tex.z-dn.net/?f=P%28r%3D0%29%5E%7B24%7DC_0%280.17%29%5E0%280.83%29%5E%7B24%7D%3D%280.83%29%5E%7B24%7D%3D0.0114)
(b)Exactly one have invalid license i.e. r=1
![P(r=1)=^{24}C_1(0.17)^1(0.83)^{23}=24\times 0.17\times (0.83)^{23}](https://tex.z-dn.net/?f=P%28r%3D1%29%3D%5E%7B24%7DC_1%280.17%29%5E1%280.83%29%5E%7B23%7D%3D24%5Ctimes%200.17%5Ctimes%20%280.83%29%5E%7B23%7D)
![=0.0561](https://tex.z-dn.net/?f=%3D0.0561)
(c)At least 2 will have invalid license i.e. ![r\geq 2](https://tex.z-dn.net/?f=r%5Cgeq%202)
![P(r\geq 2)=1-P(r=0)-P(r=1)](https://tex.z-dn.net/?f=P%28r%5Cgeq%202%29%3D1-P%28r%3D0%29-P%28r%3D1%29)
![P(r\geq 2)=1-0.0114-0.0561](https://tex.z-dn.net/?f=P%28r%5Cgeq%202%29%3D1-0.0114-0.0561)
![P(r\geq 2)=0.932](https://tex.z-dn.net/?f=P%28r%5Cgeq%202%29%3D0.932)
Answer:
x is 66 degrees
Step-by-step explanation:
since its a isosceles, two of the angles should be the same.
The perimeter will be
.. P = 2√(16^2 +30^2) = 2*34 = 68
