Calculate the mean, median, and mode of the following set of data. Round to the nearest tenth. 7, 3, 2, 1, 13, 8, 1, 5, 14, 11, 15 mean = 7.3, median = 8, mode =1 mean = 6.7, median = 7, mode = 1 mean = 7.3, median = 7, mode = 1 mean = 6.7, median = 7, mode = 8

Mean = 7.3, median = 7, mode = 1.

Step-by-step explanation:

First arrange the data in order:

1 1 2 3 5 7 8 11 13 14 15

There are a total of 11 values.

Median = middle value = 7.

Mode = the most common number = 1.

Mean = sum / 11

=  80 / 11

=  7.3.

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

the answer is a
