Consider the following table of arrival and burst time in ms for three processes P0, P1, and P2.
 

The preemptive shortest job first scheduling algorithm is used. Scheduling is carried out only at arrival or completion of processes. What is the average waiting time for the three processes?

Assume transaction A holds a shared lock R. If transaction B also requests for a shared lock on R, it will

The total time taken by a process to complete execution is called

For which value of $ x $, the matrix $ A $ has no inverse where $$ A = \begin{pmatrix} 8 & x & 0 \\4 & 0 & 2 \\12 & 6 & 0 \end{pmatrix} $$

If $$ A = \begin{pmatrix} -5 & -8 & 0 \\3 & 5 & 0 \\1 & 2 & -1 \end{pmatrix} $$ then $ A^2 $ is:

The following improper integral $$ \int_1^\infty \frac{dx}{x^p} $$ converges for which value of $ p $?
The value of $$ \lim_{x \to 0} (1 + 2x)^{1/x} $$ is
The quadratic equation $ 2x^2 - 3x + 3 = 0 $ is to be solved numerically starting with initial guess $ x_0 = 2 $. The new estimate of $ x $ after the first iteration using the Newton-Raphson method is
For the function $ f(x) = x^2 e^{-x} $, the maximum occurs when $ x $ is equal to
Two of the eigenvalues of a 3x3 matrix are -1 and 2. The determinant of the matrix is 4. Then the third eigenvalue is
If the Boolean expression $ (p \Rightarrow q) \Leftrightarrow (q \land (\sim p)) $ is a tautology, then the Boolean expression $ (p \land (\sim q)) $ is equivalent to
A pair of dice is thrown. The probability that the sum is neither 7 nor 8 is
Let $ X $ be a continuous random variable denoting the temperature measured. The range of temperature is $ [0, 100] $ degrees Celsius and let the probability density function of $ X $ be $ f(X) = 0.01 $ for $ 0 \leq X \leq 100 $. The mean is
