[Solved] Given arrays:a = np.array([1, 2, 3]) b = np.array([4, 5, 6])Which code correctly computes the element-wise average of a and b? | NumPy

NumPy - Array Operations

Given arrays:

a = np.array([1, 2, 3])
b = np.array([4, 5, 6])

Which code correctly computes the element-wise average of a and b?

Anp.mean([a, b])

B(a + b) / 2

Cnp.average(a, b)

Da + b / 2

Step-by-Step Solution

Solution:

Step 1: Calculate element-wise sum
a + b adds elements pairwise.
Step 2: Divide sum by 2 element-wise
Dividing by 2 computes average for each element.
Final Answer:
(a + b) / 2 -> Option B
Quick Check:
Element-wise average = (a + b) / 2 [OK]

Quick Trick: Add arrays then divide by 2 for element-wise average [OK]

Common Mistakes:

Using np.mean on list returns scalar
Misusing np.average
Wrong operator precedence
