q1- Which of the following code snippets uses Python to define a function called upper_slice, which takes in a string and an integer as arguments and returns the string slice up until the index of that integer, converted to all caps? Sample input 1: 'Greetings', 5 Sample output 1: 'GREET' Sample input 2: 'Hello, World!', 2 Sample output 2: 'HE'

Group of answer choices

None of these

def upper_slice(text, number) text[0,number].upcase end

def upper_slice(text, number): return text[:number].upper()

function upper_slice(text, number) { return text.slice(0, 5).toUpperCase(); }

def upper_slice(text): return text.upper()

q2-

escribe what the following line of code is doing: np.corrcoef(x, y) You can assume that it is part of a larger body of code where np, x, and y have been defined

Group of answer choices

Using the NumPy library (imported as alias np) to find the Pearson correlation between x and y

Using base Python built-in functions to find the covariance between x and y

This code would throw an error; there is no np.corrcoef function

None of these

Using base Python built-in functions to find the Pearson correlation between x and y

Using the NumPy library (imported as alias np) to find the covariance between x and y

q3-
