Answer:
"B3 and B6 will selected"
Explanation:
- If the worksheet is opened by the user and he is in the cell B3, then the B3 and B6 are selected, If the user clicks the B6 after pressing the ctrl and the shift key.
- The shift and ctrl are used to select any two cells in the MS-Excel worksheet.
- The above question asked about which cell is selected when the user in on cell B3 and press the B6 while holding the ctrl and shift key. So the answer is "B3 and B6".
Answer: The answers to all parts of this question are based on "automatic string". The condition is also provided which states that the string the machine outputs is the same string (4-digit string) which is fed to the machine as input.
Explanation: (a) The string will not remain automatic string if it contains a digit greater or equal to $5$. As we know that machine should print the same string which is fed into it. In this case the machine will insert a 0 in place of $5$. So the number is inserting a 0 when it is output by the counting machine. For example if we input $2152$ machine will print "$0120$" which shows that the digits are not the same as fed to the machine. If we take string $0702,$ which is given in the question, we see that machine prints out "$2010$" which means that number is inserting a 0 so automatic string cannot contain a digit greater than $5$
(b) The same answer as given in (a). For example the if we write $4220$ machine prints out "$1020$". So the automatic string cannot contain $4.$
(c) This is a bit tricky as machine count the digit $3$. Lets take an example string $3303$. the machine prints out "$1003$". It counts three BUT its not an automatic string because the string printed out is different from the string that was fed to the machine. So automatic string cannot contain $3.$
(d) Now we know that an automatic string cannot contain digits 3,4,5 and above. So it can contain digits 0,1 and 2 with 0 at the end as the automatic string cannot contain digit 3 or above.Lets take a few examples of strings with combinations of 0,1 and 2 to check if they are automatic strings.
- $1220$ the machine prints $1120$ which is not the same as fed into machine so its not an automatic string.
- $2020$ the machine prints out "$2020$". Its 2 times "$0$", 0 times "$1$",2 times "$2$" and 0 times "$3$" which is the same as fed to machine so $2020$ is an automatic string.
- $1210$ is an automatic string as the machine prints out "$1210$" which is the same string fed to machine.
Answer:
-1/12
Explanation:

look up the derivation by Srinivasa Ramanujan for a formal proof.
Answer:
The answer is "Phreaker".
Explanation:
A "Phreak" is one who secretly hacks into another telephone network, it is usually to make individual long-distance calling or to access the telephone lines.
- Sometimes, it involves anyone, who breaches or wants to break any information security.
- It is used to receive unlimited calls and texts or high-cost contact details, that's why the Phreaker is the correct answer.
