Rationale

14.989

To find the sum of the numbers 3.7, 7.289, and 4, we must add them together while ensuring all decimal places are accurately reported. The correct calculation yields a total of 14.989.

A (14.989) CORRECT

This choice accurately represents the sum of the numbers when calculated correctly: 3.7 + 7.289 + 4 equals 14.989, with all decimal places included.

B (5.226) YOUR ANSWER

This option is significantly lower than the correct sum. It appears to be a miscalculation, possibly resulting from incorrect addition or misunderstanding of the values involved. The three numbers combined clearly exceed this value.

C (15) YOUR ANSWER

While this choice is close to the correct answer, it lacks precision. The actual sum, including all decimal places, is 14.989, which is not rounded to 15. This indicates a loss of significant figures that should be maintained in this context.

D (15.07) YOUR ANSWER

This answer also overshoots the actual sum. It suggests an incorrect addition or rounding error, as the total when calculated accurately amounts to 14.989, which is less than 15.07.

Conclusion

The correct sum of 3.7, 7.289, and 4 is 14.989, reflecting an accurate calculation of these numbers with all decimal places included. The other choices either misrepresent the sum or disregard the importance of maintaining decimal precision in their answers.
