Final answer:
Given that lowercase and uppercase letters are considered the same, there are 26 options for each of the 7 positions in a username. Thus, the total number of possible usernames is 26^7, which equals 8,031,810,176.
Explanation:
The question involves calculating the number of possible usernames a local area network can have given certain constraints. Since lowercase and uppercase letters are considered the same, and the username requires seven letters without considering numbers, dots, or underscores, we'll only consider the 26 letters of the alphabet. Therefore, for each of the seven positions in the username, there are 26 possibilities.
The total number of possible usernames can be calculated by raising the number of possible letters (26) to the power of the length of the usernames (7), which is 26^7.
This gives us a total of 8,031,810,176 possible usernames for the local area network.

Calculate the average (as a double) of the values contained in the integer variables num1, num2, num3 and assign that average to the double variable avg. assume the variables num1, num2, and num3 have been declared and assigned values, and the variable avg declared.
Final answer:
To find the average of the integer variables num1, num2, and num3 as a double, sum the variables, cast the sum to double, and divide by the number of variables, which in this case is 3.
Explanation:
To calculate the average as a double of the values contained in the integer variables num1, num2, and num3, you would first sum those values. Then, you divide the total sum by the number of items you have, which in this case is 3, since you're dealing with three values. The formula to calculate the average (avg) would look like this:
avg = (double)(num1 + num2 + num3) / 3;Here, you are casting the sum of num1, num2, and num3 to a double to ensure the division is done using floating-point arithmetic, giving a double result which is stored in the variable avg. This is necessary because if the sum is not cast to a double, integer division would occur, potentially leading to an incorrect average due to truncation (cutting off the decimal points).
