The mean of a data set is
a.
the most commonly occurring data point in a data set
b.
the arithmetic average of the data points in a data set
c.
the middle point of a data set arranged in increasing order
d.
the difference between the greatest and least data points in the data set

B.  the arithmetic average of the data points in a data set

Step-by-step explanation:

Option (A) is not correct as it is the definition of Mode not Mean.

Option (C) is incorrect as it is the definition of Median not Mean.

Option (D) is incorrect as it is the definition of Range not Mean.

Further, Mean is used to measure the central tendency of data which represents the whole data in the best way. It can be found as the ratio of the sum of all the observations to the total number of observations.

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
