This program accepts a number as input and raise it to the .5 power (i.e., x ** .5). a = float(input("Enter a number: ")) print (a ** .5) The program is run, using the following numbers as input: 16, 25, 36, 49. The outputs are 4, 5, 6 and 7 respectively. Based on this output, what can you conclude this code does?

It finds the square root of the input number.

It finds the cube root of the input number.

It converts the input number to a decimal.

It takes the absolute value of the input number.

Which of the following is NOT true about the random functions?

They are contained in the math module.

They use the system time to seed the values.

They do not generate truly random numbers.

They are contained in the random module.

Three of the following values could be stored as strings. When would you NOT use a string command?

To store values NOT used for calculations.

Consider the following code: x = int(input("Enter a number: ")) print (x) What happens if the user types in A?

This would cause an error: an integer variable cannot store a string.

This would cause an error: int and input cannot be used together in the same line.

The following code is intended to find the average of three numbers entered from the keyboard. What is wrong with the code? print ("Enter 3 numbers: ") n1 = float(input ("Enter a number: ")) n2 = float(input ("Enter a number: ")) n3 = float(input ("Enter a number: ")) print (n1 + n2 + n3 /3)

The code is missing parentheses around n1 + n2 + n3 in the last line.

n1, n2, and n3 should use the str command instead of the float command.

Nothing, it correctly finds the average of the three numbers.

Nothing, it correctly finds the sum of the three numbers.

Why can it be helpful to perform mathematical calculations using programming? Choose the best answer.

Because computers can quickly do calculations much larger and complex than humans.

Programming is an important skill.

Because the values stored in variables cannot change.

Because computers are used to store digital data, not analog.

What is wrong with the following code? There may be more than one answer. n1 = input("Enter a number: ") n2 = input("Enter a number: ") n3 = input("Enter a number: ") print ("The average is: " + str( n1 + n2 + n3 /3))

It is missing ( ) in the last line to correctly calculate the average.

There should be a float function on the input commands.

It is missing a pow in the last line to correctly calculate the average.

Nothing, it correctly finds the average of the numbers.
