Basically this inequality
means that all valuse that are greater than 3. In this case, in 2D
representation, we plot y=3, but use a dotted line, it signifies
that the value of y may not take the value shown i.e y is not eual
to 3 . By shading we indicate which side of permitted value y
takes. The graph is below-

It is thought that prehistoric Indians did not take their best tools, pottery, and household items when they visited higher elevations for their summer camps. It is hypothesized that archaeological sites tend to lose their cultural identity and specific cultural affiliation as the elevation of the site increases. Let x be the elevation (in thousands of feet) of an archaeological site in the southwestern United States. Let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a...

In West Texas, water is extremely important. The following data represent ph levels in ground water for a random sample of 102 West Texas wells. A pH less than 7 Is adidic and a pH above 7 is alkaline. Scanning the data, you can see that water in this region tends to be hard (alkaline). Too high a pH means the water is unusable or needs expensive treatment to make it usable.t These data are also available for download at...
