Answer:

laser point

remote control

-Laser point: is a small device that has a visible light which allows the presenter to highlight things from any place where he is.

-Remote control: Is a device that helps the presenter to control the projector from the distance to handle what's being showed in the presentation which gives him/her the liberty to move as the presenter won't have to stand next to the computer.

Write Python algebraic expressions corresponding to the following statements: (a) The sum of the first five positive integers (b
lbvjy [14]

Answer:

#part a

#sum of first 5 positive number

Sum=5*(5+1)/2

print("sum of first 5 positive integer is: ",Sum)

#part b

# declare age of all

Sara_age=23

Mark_age=19

Fatima_age=31

ave_age=(Sara_age+Mark_age+Fatima_age)/3

print("average age of Sara,mark and Fatima is: ",ave_age)

#part c

#find number of times

no_of_times=int(403/73)

print(" number of times when 73 goes into 403 is: ",no_of_times)

#part d

#find remainder

rem=403%73

print("when 403 is divided by 73 then remainder  is: ",rem)

#part e

#calculate 2 to pawer 10

two_pow=2**10

print("2 to power  10 is: ",two_pow)

#part f

#declare height of both

sara_h=54

mark_h=57

diff_h=abs(sara_h-mark_h)

print("The absolute difference between height of Sara and Mark is: ",diff_h)

#part g

#find the minimum among three

print("lowest price among the three($34.99,$29.95,$31.50) is: $",min(34.99,29.95,31.50))

Explanation:

In part a, sum of first 5 positive number is calculated as 5*(5+1)/2.In part b, add the age of three and divide it  by 3. In part c, use "/" to find number of times 73 goes into 403.In part d, use "%" to find remainder when 403 is divide by 73.In part e, 2 to the 10th power is calculated as 2**10.In part f, use abs() to find the absolute  difference.In part g, min() function is used to find lowest among the 3 prices.

Output:

sum of first 5 positive integer is:  15.0                                                                                  

average age of Sara,mark and Fatima is:  24.333333333333332                                                                

number of times when 73 goes into 403 is:  5                                                                              

when 403 is divided by 73 then remainder  is:  38                                                                          

2 to power  10 is:  1024                                                                                                  

The absolute difference between height of Sara and Mark is:  3                                                            

lowest price among the three($34.99,$29.95,$31.50) is: $ 29.95

Which of the following statement is False? 1 point Context free language is the subset of context sensitive language Regular lan
alisha [4.7K]

Answer:

Context-sensitive language is a subset of context-free language

Explanation:

Considering the available options, the statement that is considered wrong is "Context-sensitive language is a subset of context-free language."

This is because generally every regular language can be produced through the means of context-free grammar, while context-free language can be produced through the means of context-sensitive grammar, and at the same time, context-sensitive grammars are produced through the means of Recursively innumerable.

Hence, the correct answer in this correct answer to the question is the last option *Context-sensitive language is a subset of context-free langage

Program:

public class data //defining class data

{

//main method

public static void main (String [] as) //declaring main method  

{

int userNum = 4; //declare variable userNum and assign value

for (userNum = 1; userNum <= 4; userNum++)  //loop for print values

{

System.out.println(userNum);  //print values in new lines.

}

}

}

Output:

1

2

3

4

Explanation:

In the above java program code firstly a class "data" is defined, inside this class the main method is defined in which an integer variable userNum is defined that holds a value that is "4".

  • In this method, a for loop is declare that uses variable userNum which starts from 1 and ends with a given value that is equal to 4.
  • Inside a for loop, the print function is used that print userNum variable each values in the newline.
