Question: We consider a random variable X uniformly distributed in the interval [5, 6], and Y a second variable whose conditional distribution knowing X = x

We consider a random variable X uniformly distributed in the interval [5, 6], and Y a second variable whose conditional distribution knowing X = x is exponential with parameter = x.

Calculate the variance of the variable T = 30- 9X + 7Y.
