Answer 2

To calculate the sum of these numbers, you simply need to add them together:

4.9 + 5.4 + (-3.6) + 4.9 + (-7.2) + 4.2 + (-1.9)

Now, add these numbers:

4.9 + 5.4 = 10.3 10.3 + (-3.6) = 6.7 6.7 + 4.9 = 11.6 11.6 + (-7.2) = 4.4 4.4 + 4.2 = 8.6 8.6 + (-1.9) = 6.7

So, the sum of these numbers is 6.7.
