Show answer & explanation
Correct answer: C
Compute the weighted sum (net input): (-3.9 × 1.3) + (1.1 × 2.2) = -5.07 + 2.42 = -2.65
Activation rule: The perceptron outputs 1 if the weighted sum ≥ threshold (0.3); otherwise it outputs 0.
Compare the weighted sum to the threshold: -2.65 < 0.3, so the perceptron output is 0.
Final answer: 0
