Question

How would I do this?

Propagate to find the percent error in a + b.
a = 8.3 ± 1.2
b = 11.7 + 1.6
Enter a number such as ##. Don't include a "%".

Expert Solution

Step 1

Solution:

Here we are given that

$a = 8.3 \pm 1.2 and b = 11.7 \pm 1.6$

now here let the relation be :

$x + ∆ x where, x = a + b a n d, ∆ x = \pm (∆ a + ∆ b)$

Therefore, we have:

$x = a + b = 8.3 + 11.7 = 20 ∆ x = (∆ a + ∆ b) = 1.2 + 1.6 = 2.8$
