Find the range, mean, median, and mode of the following data set.
21, 14, 2, 9, 12, 3, 1, 8, 20
a.
range 17
mean 10
median 9
mode 9
c.
range 20
mean 11
median 9
mode none
b.
range 20
mean 10
median 12
mode none
d.
range 20
mean 10
median 9
mode none

The answer to your question would be D.

D. Range: 20

Mean: 10

Median: 9

Mode: none

Step-by-step explanation:

1, 2, 3, 8, 9, 12, 14, 20, 21

Range: 21 - 1 = 20

Mean: 1 + 2 + 3 + 8 + 9 + 12 + 14 + 20 + 21 = 90/9 = 10

Median: 9

Mode: there are no mode in the following given data set.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
