helpppp
Trevian: From dummies.com, and yes, i was wrong too. Radius: A circle's radius - the distance from its center to a point on the circle - tells you the circle's size. In addition to being a measure of distance, a radius is also a segment that goes from a circle's center to a point on the circle. Chord: A segment that connects two points on a circle is called a chord. Diameter: A chord that passes through a circle's center is a diameter of the circle. A circle's diameter is twice as long as its radius.

Why?
marcotoia: if you subtract 100 to 125 you have the not accettable bolts, they are 5. now, do a proportion 100:125=x:5 and x=100*5/125=4%

Slick Rick 88 asked · 18 Feb 2020
It shouldn't be y=2?
Carlotambo66: because if you look the straight line with the x on final, that's the y=0 and the equation the the question in talking about is the line under the x line

Alexandru_ciobu asked · 16 Apr 2019
why is it 2?
MaintenanceMike: the condition that determines the y axis intercept is x=0, therefore put x=0 and you obtain 4y=8 then divide each member by 4
