Answer i'm giving out a , follow, and a brainliest.

The mode of a set of numbers is the number that occurs the most.

The numbers in this set are as follows,

26, 17, 9, 12, 18, 21, 9, 14, 18, 23, 15, 7, 20, 18, 17, and 12

26 I

17 II

9 II

12 II

18 III

21 I

14 I

23 I

15 I

7 I

20 I

The number that appears the most is 18!

So the mode of the set of numbers is 18!

In order to find the mode, you have to rearrange the numbers to be least to greatest.

7, 9, 9, 12, 12, 14, 15, 17, 17, 18, 18, 18, 20, 21, 23, 26

Now you want to find the mode of the weights, or set of numbers.

The mode is the most frequently occuring value (or values) in a set of data. A data set may have no mode, one mode, or more than one mode.

So, the most occuring number(s) are/is 18.

One 7, 14, 15, 20, 21 23, 26.

Two 9's, 12's, 17's.

Three 18's.

So, 18 is the mode of these weights.
