Answer:

<em>SQL Query</em>

//////////////////////////////////////////////////////////////////////////////////////////////////

select student_name from Student

INNER JOIN Class ON Student.id = Class.student_id

LEFT JOIN Instructor ON Class.instructor_id = Instructor.id

WHERE Instructor.school <> 'Computer Science'

Explanation:

First thing is to select the student_name from <em>Student</em> table.

Next we need to connect with the <em>Class</em> table to get all Students currently taking classes.

Next we need to connect the <em>Class</em> table with the <em>Instructor</em> table, to get all of the Instructors currently teaching class(s).

Finally, we place the Where condition for the acquired instructors to not be from the Computer Science department.

Write a function that takes in two parallel lists: a list of times (in increasing order), and a list of distance traveled by tha
Georgia [21]

Below is the function that takes two parallel lists;

List of times in increasing order and that of distance travelled by that point in time.

I put into consideration the instructions given in the question.

ANSWER;

def find_velocity(time, distance):

velocities = []

for i in range(1, len(time)):

velocities.append((distance[i] - distance[i - 1]) / (time[i] - time[i - 1]))

return velocities

times are = [1, 3, 5, 7]

distances are = [25, 29, 35, 70]

print(find_velocity(times, distances))

Two communicating devices are using a single-bit even parity check for error detection. The transmitter sends the byte 10101010
icang [17]

Answer:

The receiver will not detect the error.

Explanation:

The byte sent by transmitter: 10101010

The byte received by receiver due to channel noise: 10011010

If you see the bold part of the both sent and received bytes you can see that the number of bits changed is 2.

The two communicating devices are using a single-bit even parity check. Here there are two changed bits so this error will not be detected as this single bit even parity check scheme has a limit and it detects the error when the value of changed bit is odd but here it is even.

This parity scheme basically works well with the odd number of bit errors.
