An auto parts manufacturer produces gaskets that are 4 .010 units in diameter.
00:09
The tolerance allotted for the diameter of the gaskets is two, what is that, 10th, hundreds, 10 ,000th of a unit.
00:19
Which of the following inequalities could be used to determine if a gasket's diameter d is acceptable? so if we think about this problem by saying, okay, well, there's a minimum acceptability and a maximum acceptability.
00:32
To describe that minimum, we would say that the diameter has to be greater than or equal to the 4 minus the 0 .002.
00:44
The maximum has to be that diameter, that maximum diameter has to be smaller than less than or equal to whatever happens when we add those two values together.
00:55
If we solve both of those equations, right, make it so that it's equal to that 4 .01.
01:05
So i'm going to, sorry, i'm subtracting that 4 .01.
01:08
I'm going to make it to that tolerance so that my two equations end up with the same value on the left hand side...
