"Write an SQL query that displays the Ssn and Last name of all employees who is a supervisor of a Department Manager"


Answer 1




 FROM employees

WHERE position = supervisor;


SELECT is an SQL query statement that is used to initiate the display of wanted variables.

The names of the variables often succeed the SELECT statement and they are separated by commas.

FROM is an SQL query statement that indicates the table fro which the selected variables be displayed.

WHERE is used to filter your search and return only rows that meet the criteria.

; signifies the end of a query and calls for an execution.

Write a function in Matlab which takes as input an integer x and as output returns the biggest prime number that is less than or equal to x. For example, if the input is 7, the output would be 7. If the input is 40, the output would be 37. (Reminder: isprime.)




The objective is to write a Matlab function getPrime()


function prime = getPrime(x) %function definition for getPrime which receives x as input and returns prime.

   while (x >= 1) % loop until x is zero.

       if isprime(x) % matlab built-in function to check if x is a prime number.

           prime = x; % assign x to prime.

           break % break out of loop. we got the prime number value in variable prime.


       x = x - 1; % when x is not prime, x is decremented by 1 and loop continues.



prime = getPrime(12); % passes 12 to function.

disp(prime) % display value in prime. 11 is the output since it is the biggest prime number below 12.

Make a program that asks for input from the user, apply eval to this input, and print out the type of the resulting object and its value. Test the program by providing five types of input: an integer, a real number, a complex number, a list, and a tuple.



x = input("Input a number ")


print ("Type is:",type(x))

#Taking an float input

y = input("Input a number ")


print ("Type is:",type(y))

#Taking an complex input

z = complex(input("Input a number "))


print ("Type is:",type(z))

#Taking an List input

L_num = raw_input().split(",")


print ("Type is:",type(L_num))

#Taking an tuple input.

T_num = raw_input().split(",")


print ("Type is:",type(T_num))
