The answer is C.
Formulas within table cells always begin with an equal sign.
Here is the sample of some of the formulas :
1. Sum (equation)
=SUM(5, 5) or =SUM(A1, B1) or =SUM(A1:B5)
2. Count ( to count number of cells or rows)
=COUNT(A1:A10)
3. Trim ( Get rid of any space in a cell)
=TRIM(A1)
4. Vlookup ( to look up data from a vertically structured table)
=VLOOKUP(lookup_value, table_array, col_index_num, range_lookup)
5. if statements
=IF(logical_statement, return this if logical statement is true, return this if logical statement is false)
Answer:
In Python:
def fib(nterms):
n1, n2 = 1, 1
count = 0
while count < nterms:
term = n1
nth = n1 + n2
n1 = n2
n2 = nth
count += 1
return term
Explanation:
This line defines the function
def fib(nterms):
This line initializes the first and second terms to 1
n1, n2 = 1, 1
This line initializes the Fibonacci count to 0
count = 0
The following while loops gets the number at the position of nterms
<em> while count < nterms:
</em>
<em> term = n1
</em>
<em> nth = n1 + n2
</em>
<em> n1 = n2
</em>
<em> n2 = nth
</em>
<em> count += 1
</em>
This returns the Fibonnaci term
return term
Answer:Screening
Explanation:Packet screening is the process in which whenever a packet is received at the destination port, there is the examining of the packet.The examination of the packet rote from source to destination takes place. The screening takes place for evaluating that the data in the packet is adequate and carries no error that can risk in the security, tracks the routes of the packet path etc.
Answer : Encoding

Answer and Explanation:
Some of the negative aspects of robots at work place:
- Lesser flexibility
- Higher maintenance and installation cost
- Future insecurity and risk if the system malfunctions
- A decline in the opportunities for humans
- Unemployment as a result of automation and robot regulated work place.
Some of the positive aspects of robots at work place:
- Higher accuracy
- Higher speeds
- More work in less time
- Productivity and hence efficiency will increase
- Cost of some operations is reduced.
- Ease of employing in dangerous and hazardous fields by using specific robots for each task
