Answer:
The correct answer for the given question is " The Code fragment A runs fastly than the code fragment of B".
Explanation:
In this question there are some information is missing i. e options. The question does not give any options. The options for the given question is given below
(A.) The Code fragment A runs fastly than the code fragment of B.
(B.) The Code fragment B runs fastly than code fragment of A.
(C) The Code fragment A runs as fastly as code fragment of B.
So we conclude the answer i.e option(A) because As given in the question list1 is a MyArrayList and list2 is a MyLinkedList. , in list1 we fetching the data easily and fastly means that it remove the data easily as compare to list2 As MyArrayList is storing the list only and also we can fetch the data easily manner.
The list2 is an object of MyLinkedList means that it manipulating the data fastly as compared to MyArrayList but if we compared the fetching of data then MyArrayList is a better option so the code fragment runs fastly then code fragmented B.
Answer:
Probability Distribution={(A, 4/7), (B, 2/7), (C, 1/7)}
H(X)=5.4224 bits per symb
H(X|Y="not C")=0.54902 bits per symb
Explanation:
P(B)=2P(C)
P(A)=2P(B)
But
P(A)+P(B)+P(C)=1
4P(C)+2P(C)+P(C)=1
P(C)=1/7
Then
P(A)=4/7
P(B)=2/7
Probability Distribution={(A, 4/7), (B, 2/7), (C, 1/7)}
iii
If X={A,B,C}
and P(Xi)={4/7,2/7,1/7}
where Id =logarithm to base 2
Entropy, H(X)=-{P(A) Id P(A) +P(B) Id P(B) + P(C) Id P(C)}
=-{(1/7)Id1/7 +(2/7)Id(2/7) +(4/7)Id(4/7)}
=5.4224 bits per symb
if P(C) =0
P(A)=2P(B)
P(B)=1/3
P(A)=2/3
H(X|Y="not C")= -(1/3)Id(I/3) -(2/3)Id(2/3)
=0.54902 bits per symb
Answer:
<em>The right order of steps you should take to repare the laptop is: D A C B</em>
<em>Explanation:</em>
<em>D. Ask yourself if the laptop is still under warranty: Because they will replace the board for you or give you a new machine.</em>
<em>A. Ask yourself if replacing the motherboard will cost more than purchasing a new laptop: since technology evolve every day, you might consider buying a new faster, better, advanced machine.</em>
<em>C. Find the service manual to show you how to replace the motherboard: the support assistence will guide you trhough the right way of replacing the board.</em>
<em>B. Find a replacement motherboard: choose the specific one or maybe try to find a better model, that can improve your computer performance.</em>
Answer:
The Statement for selecting values from the table in SQL is given below,
SELECT vendor_name, vendor_contact_last_name, vendor_contact_first_name FROM Vendors;
Explanation:
SQL stands for Structured query language which is used to insert, update, delete and modify the value in a table.
There are five types of SQL-
1. Data definition language
2. Data manipulation language
3. Data control language
4. Transaction Control Language
5. Data Query Language
The SELECT statement comes under DDL which is used to select and display values from a table.
We can use select statement in two ways-
1. SELECT column_name1, column_name2 ........column_nameN FROM Table_name;
2. SELECT * FROM tablename; ( This is used to select all values from the table name)
We can also give conditions using WHERE clause while selecting values.
