Question

Given that w = x + y /z ,x = 2.5 ± 0.5 , y = 1.5 ± 0.5 and z = 1.1 ± 0.1 ,find the lower and upper bounds of w

Answer 1

Answer:

6000000000000000000000000000

Answer 2

Answer:

w(max) = 5, w(min) = 2.5, so the solutions on the IG textbook is wrong.

Step-by-step explanation:

w(max) = (3+2)/1 = 5, w(min) = (2+1)/1.2 = 2.5
