5,12,8,6,2,10,7 find the measure of central tendency

Median = 7; Mode = None; Mean = 7.14

Step-by-step explanation:

Measures of Central Tendency represent the distribution of a set of numbers or data.  Median represents the middle number when ordered from least to greatest, Mode represents the most occuring number and Mean represents the average.  In this case, the first step is to number the data set in order from least to greatest (2, 5, 6, 7, 8, 10, 12).  Then you find the middle number in the set of data, which in this case is 7.  Next, you look for the most occuring number, but since all numbers in this data set occur only once each, there is no Mode.  Mean is the average, or the sum of all the numbers divided by the total numbers in the data set (50/7), or 7.14.  

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
