Answer:
By Using the Greedy- Activity- Selection algorithm
Explanation:
The Greedy- Activity- Selection algorithm in this case involves
First finding a maximum size set S1, of compatible activities from S for the first lecture hall.
Then using it again to find a maximum size set S2 of compatible activities from S - S1 for the second hall.
This is repeated till all the activities are assigned.
It requires θ(n2) time in its worse .
Answer:
Option is b is correct answer. Excel performs exponentiation, then multiplication and division, then addition, and subtraction, it is correct order of operation in Excel. It is important to remember when you write any formula in Excel having different mathematical operators like +/ -/ ^/ etc, it follows a specific order and performs calculations in specific order which is termed as order of operator precedence. Each of mathematical operator has its precedence and executes in a special order set by Excel.
Explanation:
- As we already know order of precedence of each mathematical operator is different in Excel. The order of operations for Excel is as follows:
- Evaluate elements in parentheses.
- Evaluate 'ranges' ().
- Evaluate 'intersections' (empty spaces).
- Evaluate 'unions' (,).
- Perform negation (-).
- determine percentages (%).
- Perform exponentiation (^).
- Perform multiplication (*) and division (/), both are of equal precedence.
- Perform addition (+) and subtraction (-), both are of equal precedence.
- Evaluate text operators like (&).
- Perform comparisons like (=, <>, <=, >=).

Answer:
Back up the user data to removable disk
Explanation:
Before you work on a computer, especially anything that has to do with files not accessible, this might need to format the system because it might either be a virus or other forms of malware. Since backup was done to a different logical partition on the disk, the first thing to do before performing any diagnostic procedures on the disk is to back up the user data to a removable disk in order not to lose the information in the system.
Answer:
Polymorphism means that a variable of supertype can refer to a subtype object.
Explanation:
For example, in Python programming language, a function that accepts an iterable object uses the concept of polymorphism because that function can accept strings, lists, tuples as arguments.
