B. Weighted average

C. Median

D. Mode

Answer 1

The machine calculates the result of 4.9 based on Jane's answers using weighted average.

Step-by-step explanation:

The machine calculates the result of 4.9 based on Jane's answers using weighted average. In a weighted average, each answer is assigned a weight or importance. The weights are multiplied by the corresponding scores, and then the weighted scores are added together and divided by the total weight. In this case, the total weight is 60 (10 questions multiplied by a maximum score of 6), and Jane's total weighted score is 29.4 (6*6 + 6*6 + 6*6 + 3*6 + 2*6 + 2*6 + 1*6 + 1*6 + 3*6 + 1*6). Dividing 29.4 by 60 gives us an average of approximately 0.49, which we can round to 0.5 for simplicity.
