log2() Base-2 logarithm of x.
Answer:
Healthy plant growth follows from sufficient water.
Contrapositive: If water is insufficient, then there isn't healthy plant growth
Increased availability of information is a necessary condition for further technological advances
Contrapositive: Absence of further technological advances implies decreased availability of information.
Errors were introduced only if there was a modification of the program.
Contrapositive: If there wasn't any modification of the program then error was not introduced into the program
Fuel savings implies good insulation or storm windows throughout.
Contrapositive: The absence of good insulation or storm windows throughout implies that there is no fuel savings.
Explanation:
A contrapositive statement is formed from a conditional statement as we can see from the answers above.
In a contrapositive statement, we just interchange the hypothesis and the conclusion of the inverse statement.
This implies that, when the converse of the statement is true, then the inverse of the statement is also logically true.
Answer:
Explanation:
a)use order by clause for sorting
for $x in doc("books.xml")/bib/book order by xs:float($x/price) return $x/title (default sorted in ascending order)
or
for $x in doc("books.xml")/bib/book order by xs:float($b/price) descending return $b/title (sorted in descending order)
b)doc("books.xml")//book[author = 'Abiteboul']
c)for $x in distinct-values(doc("bib.xml")/bib/book/author)
return <res>
<name>{$x}</name>
<count>
{count (doc("bib.xml")//book[exists(indexof(author,$x))]) }
</count>
<res>
Answer:
The program to this question as follows:
Program:
targetValue = 0.3333 #defining variable targetValue and assign value
sensorReading = 0.0 #defining variable sensorReading and assign value
sensorReading = 1.0/3.0 #calculate value in sensorReading variable
Val=sensorReading - targetValue
#calculate the difference and store in Val variable
if (Val < 0.0001): #use of if block to check condition
print ("Equal") #print value
else: #else block
print ("Not equal") #print value
Output:
Equal
Explanation:
In the above Python program code, there are two variables "targetValue and sensorReading" is defined, in which targetValue store a value, that is "0.3333", and sensorReading holds a value, that is "0.0".
- In the next step, the "Val" variable is defined, that calculate the difference between both variable, that conditional statement is used.
- In if block, if the value is less then "0.0001", it will print value "Equal", otherwise, it will go to the else block, that will print "Not equal".
Computer Network, surely!
"Network" implies combination of all these computers!
