WGU Scripting-and-Programming-Foundations Dumps Questions Answers

A. round_number(4.723, 2) - This is not a valid function call because there is no function named round_number defined in the given context.

B. convort_value(12) - This is not a valid function call either. Additionally, the expected return value “cVa1” seems to be a typo or an incorrect value.

C. Printsample() - This is a valid function call. It invokes the function named Printsample.

D. CountFactors(96 integer) - This is not a valid function call. The parameter “integer” should not be included in the function call.

E. function Sample(float 2.0) - This is not a valid function call. The function name should not start with the keyword “function,” and the parameter “float 2.0” is not correctly formatted.

F. GetHeight(integer 3, integer 4) - This is a valid function call. It calls the function GetHeight with two integer arguments: 3 and 4.

Comprehensive and Detailed Explanation From Exact Extract:

The least common multiple (LCM) of two positive integers a and b is the smallest number that is a multiple of both. A function to compute the LCM requires a and b as inputs to perform the calculation (e.g., using the formula LCM(a, b) = (a * b) / GCD(a, b), where GCD is the greatest common divisor). According to foundational programming principles, the function’s inputs must include all values needed to compute the output.

Task Analysis:

Goal: Compute LCM of a and b.

Required inputs: The two integers a and b.

Output: The LCM (denoted as L in the question).

Option A: "L only." This is incorrect. L is the output (the LCM), not an input. The function needs a and b to calculate L.

Option B: "a * b." This is incorrect. The product a * b is used in the LCM formula (LCM = (a * b) / GCD(a, b)), but the function needs a and b separately to compute the GCD and then the LCM.

Option C: "a and L." This is incorrect. L is the output, not an input, and the function does not need L to compute itself.

Option D: "a and b." This is correct. The function requires the two integers a and b as inputs to compute their LCM. For example, in Python:

def lcm(a, b):

def gcd(x, y):

while y:

x, y = y, x % y

return x

return (a * b) // gcd(a, b)

Comprehensive and Detailed Explanation From Exact Extract:

A valid test checks if the algorithm produces the expected output for a given input, according to its specification. The algorithm outputs "OK" for numbers in the range [98.3, 98.9] (inclusive or exclusive bounds not specified, but typically inclusive in such problems) and "Not OK" otherwise. According to foundational programming principles, we evaluate each test case.

Specification:

Input in [98.3, 98.9] → Output: "OK".

Input outside [98.3, 98.9] → Output: "Not OK".

Option A: "Input 98.6. Ensure output is 'Not OK.'" Incorrect. Since 98.6 is between 98.3 and 98.9 (98.3 ≤ 98.6 ≤ 98.9), the output should be "OK", not "Not OK". This test is invalid.

Option B: "Input 98.6. Ensure output is 'OK.'" Correct. 98.6 is within the range, and the expected output is "OK", making this a valid test.

Option C: "Input 99.9. Ensure output is 'OK.'" Incorrect. 99.9 is outside the range (99.9 > 98.9), so the output should be "Not OK", not "OK". This test is invalid.

Option D: "Input 99.9. Ensure output is '98.9.'" Incorrect. The algorithm outputs either "OK" or "Not OK", not a numerical value like "98.9". This test is invalid.
