what set of 7 numbers have the following landmarks''''

mode 21

median 24

maximum 35

range 20

highest of 21 s

3 above 24, 3 below
between 15 and 35

so try

15 21 21 24 25 26 35

To find a set of seven numbers that satisfies these landmarks, we can use some basic math principles. Let's break it down step by step:

1. To find the mode, we need to know the number(s) that appear most frequently in the set. In this case, the mode is given as 21. This means that at least two numbers in the set should be equal to 21.

2. The median is the middle value of a set when it is ordered from least to greatest. The median is given as 24, so we need to include 24 as one of the numbers in the set.

3. The maximum is the largest value in the set, which is given as 35. We need to include 35 as one of the numbers in the set.

4. The range is the difference between the maximum and the minimum values in the set, which is given as 20. This means that the highest value in the set is 35, so the lowest value should be 15 (35 - 20 = 15).

Based on these landmarks, we can construct a set of seven numbers:

15, 21, 21, 24, 24, 30, 35

This set satisfies the given conditions.
