givi [52]

Answer: 10 seconds

Explanation:

m here means mean.

Mean or more accurately arithmetic mean, is calculated by adding all the terms and then dividing by the number of terms.

If there are 5 terms being 4, 5, 5, 6 and a fifth one which is x, and the mean is 6. The relevant expression is:

(4 + 5 + 5 + 6 + x) / 5 = 6

Solving it:

4 + 5 + 5 + 6 + x = 6 * 5

20 + x = 30

x = 30 - 20

x = 10 seconds

how do GIS,GPS,VGA,and remote sensing work together to provide us with a more complete understanding of what is happening at a l
yuradex [85]
GIS (global informational system)
GPS (global positioning system)
VGA (Video graphic array)
Remote Sensing (The scanning of earth by satellite to obtain information about it)

So now that we have the definitions down, GIS,GPS,VGA, and Remote sensing provide a better understanding of what is happening at a local or global level by explaining the steps being taking to obtain the information. GIS gathers the information of the region, GPS creates the route of the region, VGA connects the information and routes gathered by GIS and GPS to your cellular device, and Remote sensing may seem like the same concept of GIS however remote sensing uses satellite images of a wider area.

Sorry if this explanation seems long, or seems to not make sense. I'm just learning about this stuff and thought I'd try to answer (:
