Construct a SQL query that displays a list of colleges, their sity/state, the accrediting agency, and whether or not the school
Alex787 [66]

Answer:

SELECT college, city_state, accre_agency, distance LIMIT 10

Explanation:

Given

Table name: College

See attachment for table

Required

Retrieve top 10 college, state, agency and school distance from the table

To retrieve from a table, we make use of the SELECT query

The select statement is then followed by the columns to be selected (separated by comma (,))

So, we have:

SELECT college, city_state, accre_agency, distance

From the question, we are to select only first 10 records.

This is achieved using the LIMIT clause

i.e. LIMIT 10 for first 10

So, the complete query is:

SELECT college, city_state, accre_agency, distance LIMIT 10

The 7-bit ASCII code for the character ‘&’ is: 0100110 An odd parity check bit is now added to this code so 8 bits are trans
Alex787 [66]

Answer

First part:

The transmitted 8-bit sequence for ASCII character '&' with odd parity will be 00100110. Here leftmost bit is odd parity bit.

Second part:

The invalid bit sequence are option a. 01001000 and d. 11100111

Explanation:

Explanation for first part:

In odd parity, check bit of either 0 or 1 is added to the binary number as leftmost bit for making the number of 1s in binary number odd.

If there are even number of 1s present in the original number then 1 is added as leftmost bit to make total number of 1s odd.

If there are odd number of 1s present in the original number then 0 is added as leftmost bit to keep the total number of 1s odd.  

Explanation for second part:

A valid odd parity bit sequence will always have odd number of 1s.

Since in option a and d,  total number of 1s are 2 and 6 i.e. even number. Therefore they are invalid odd parity check bit sequences.

And since in option b and c, total number of 1s are 5 and 7 i.e. odd numbers respectively. Therefore they are valid odd parity check bit sequences.

Please help, will give brainliest!!! I need help with these coding questions, any help is appreciated
olchik [2.2K]

Answer:

class Foo:

   def F(self, n):

       if n == 1:

           return 1

       return self.F(n - 1) + 3 * n - 2

Explanation:

This should cover part a to this question. The thing I'm not sure on is they use the term "method" which in python technically means a class function...but then list one argument with the function call which makes me think it is possibly just supposed to be a regular function. Which would be the following snippet. It would depend on if you are using classes or not yet in your coding class.

def F(n):

   if n == 1:

       return 1

   return F(n - 1) + 3 * n - 2

Play around with it and look into python "lists" and "for loops" for part c. Part b I'm not sure what kind of example they want since I'm not in that class. Good luck!
