Answer:
Age= 15
Step-by-step explanation:
Let a be for age at the moment
(a-3)^2 =6(a+9)
a^2-6a+9=6a+54
a^2-12a-45
(a-15)(a+3)
a=15 or a=-3
Age cannot be negative (-)
Therefore
Age =15
It would be equal to 110 2/7
Since
![\mathrm M_Y(t)=e^{6(e^t-1}](https://tex.z-dn.net/?f=%5Cmathrm%20M_Y%28t%29%3De%5E%7B6%28e%5Et-1%7D)
, we know that
![Y](https://tex.z-dn.net/?f=Y)
follows a Poisson distribution with parameter
![\lambda=6](https://tex.z-dn.net/?f=%5Clambda%3D6)
.
Now assuming
![\mu,\sigma](https://tex.z-dn.net/?f=%5Cmu%2C%5Csigma)
denote the mean and standard deviation of
![Y](https://tex.z-dn.net/?f=Y)
, respectively, then we know right away that
![\mu=6](https://tex.z-dn.net/?f=%5Cmu%3D6)
and
![\sigma=\sqrt6](https://tex.z-dn.net/?f=%5Csigma%3D%5Csqrt6)
.
So,
Answer:
Translate the circles so they share a common center
point, and dilate circle Y by a scale factor of 3.
