Question

if e=f+g-h and f=4.1+-0.1,g=3.9+-0.3 and h=2.3+-0.2 what is e+-change in e

Answer 1

Hey!!
Here is the answer..

According to the question,

e = f + g - h ......Equation (1)

Now,
$f = 4.1 \pm0.1 \\ g = 3.9 \pm0.3 \\ h = 2.3 \pm0.2$

Hence,

f = 4.1 + 0.1 = 4.2
g = 3.9 + 0.3 = 4.2
h = 2.3+ 0.2 = 2.5

Now,
From equation (1),
e = 4.2 + 4.2 - 2.5
e= 8.4 - 2.5
$\bold{e = 5.9}$

Similarly,

f = 4.1 - 0.1 = 4.0
g = 3.9 - 0.3 = 3.6
h = 2.3 - 0.2 = 2.1

From equation (1),

e = 4.0 + 3.6 - 2.1
e = 7.6 - 2.1
$\bold{e = 5.5}$

Finally, we got the two values of 'e'..

They are 5.9 , 5.5.
