**Answer:**

Mean of the data set is one of the most commonly used measures of central tendency. Basically, it means the average value of the data set. For finding it, one doesn't have to arrange the data in order. All it takes is to add them all together and divide that by the number of the data. It can be mathematically written as:

(x1 + x2 + x3 + ..... + xn) / n

This obviously means that Ashrita did the best job in calculating the mean of this data set.

You need to graph it. The slope intercept form that is y=4x+-2/3

4 is the slope and -2/3 is the y intercept

**Answer:**

5418.54 ft

**Step-by-step explanation:**

So sea level is 0, okay? So Nadia (her name is more than 3 letters and I'm lazy so from now on she'll be reffered to as "N") is at -19. 26 ft. N goes up 5,437.8 ft, so we add this value on.

-19. 26+ 5437.8= 5418.54

Now just add on the units!

Hope this helps!

Is this a function {(2,5),(3,6),(5,2),(0,5),(8,1),(9,3)}

**Answer:**

Yes

**Step-by-step explanation:**

To be a function, no two x-values can be the same in a set of coordinates.

2, 3, 5, 0, 8, and 9 do not equal each other, so it is a function.
