. If a random variable X has the following probability distribution, then the mean of X is:
The maximum value of the function \[ f(x) = 3\sin^{12}x + 4\cos^{16}x \] is ?
Match the functions in List--I with their corresponding properties in List--II:
If the function \( f(x) \) is given by \[ f(x) = \begin{cases} \frac{\tan(a(x-1))}{\frac{x-1}{x}}, & tif0<x<1 \frac{x^3-125}{x^2 - 25} , & \text{if } 1 \leq x \leq 4 \frac{b^x - 1}{x}, & \text{if } x>4 \end{cases} \] is continuous in its domain, then find \( 6a + 9b^4 \).
