I really need help, but on how to do it. Not just the answer please...
hint: the absolute value of the difference between x and 43.6 is less than or equal to the tolerance
Um... So |x-43.6|
almost. what is the tolerance?
What does tolerance mean?
I don't know :(
"tolerance of 0.1" means that the value of x will be no more than 43.6 + 0.1, and no less than 43.6 - 0.1 basically, the tolerance gives you an upper bound and a lower bound for the possible x values
so our inequality is |x - 43.6| <= 0.1
think about what this statement means |x - 43.6| <= 0.1 |x - 43.6| represents the distance between x and 43.6. the inequality means that x will be no more than 0.1 units away from 43.6
because x has to be either 43.6 or .1+ or - 43.6. The tolerance means it has to be in that range??
uh... not quite
"tolerance of 0.1" means that the maximum value of x is 43.6 + 0.1 = 43.7 the minimum value of x is 43.6 - 0.1 = 43.5 that's why "0.1" is the tolerance value
ooh, ok thanks! @Vocaloid
