The answer is that I think it is 5
Answer:
y=2x+2
Step-by-step explanation:
Not sure if the given probability that
is 0.06 or 0.6, or something else altogether. I'll just refer to it by the number
.
![\begin{cases}P(X=0)=p\\P(X=i+1)=\frac15P(X=i)&\text{for }i\ge1\end{cases}](https://tex.z-dn.net/?f=%5Cbegin%7Bcases%7DP%28X%3D0%29%3Dp%5C%5CP%28X%3Di%2B1%29%3D%5Cfrac15P%28X%3Di%29%26%5Ctext%7Bfor%20%7Di%5Cge1%5Cend%7Bcases%7D)
As is, the probability that
is indeterminate, so I think you intended to write
![\begin{cases}P(X=0)=p\\P(X=i+1)=\frac15P(X=i)&\text{for }i\ge\boxed{0}\end{cases}](https://tex.z-dn.net/?f=%5Cbegin%7Bcases%7DP%28X%3D0%29%3Dp%5C%5CP%28X%3Di%2B1%29%3D%5Cfrac15P%28X%3Di%29%26%5Ctext%7Bfor%20%7Di%5Cge%5Cboxed%7B0%7D%5Cend%7Bcases%7D)
Then by this definition,
![i=0\implies P(X=1)=\dfrac15P(X=0)=\dfrac p5](https://tex.z-dn.net/?f=i%3D0%5Cimplies%20P%28X%3D1%29%3D%5Cdfrac15P%28X%3D0%29%3D%5Cdfrac%20p5)
![i=1\implies P(X=2)=\dfrac15P(X=1)=\dfrac p{5^2}](https://tex.z-dn.net/?f=i%3D1%5Cimplies%20P%28X%3D2%29%3D%5Cdfrac15P%28X%3D1%29%3D%5Cdfrac%20p%7B5%5E2%7D)
and so on.
Then
![\boxed{P(X\le2)=P(X=0)+P(X=1)+P(X=2)=p+\dfrac p5+\dfrac p{5^2}=\dfrac{31p}{25}}](https://tex.z-dn.net/?f=%5Cboxed%7BP%28X%5Cle2%29%3DP%28X%3D0%29%2BP%28X%3D1%29%2BP%28X%3D2%29%3Dp%2B%5Cdfrac%20p5%2B%5Cdfrac%20p%7B5%5E2%7D%3D%5Cdfrac%7B31p%7D%7B25%7D%7D)
Step-by-step explanation:
angle 2 = 180-39= 141°
angle 2 = 141°
Answer:
x = 6
Step-by-step explanation:
6 - 2x = (5-9)x +18
6 - 2x = -4x +18
2x = 12
x = 6
