Make up a set of 7 numbers having the following landmarks: mode: 21, median: 24, maximum: 35, range: 20

35, 27, 21, 15

make up 7 numbers having the following landmark. Divide by 2

To create a set of numbers with the given landmarks, we need to consider the mode, median, maximum, and range.

Given:
- Mode: 21
- Median: 24
- Maximum: 35
- Range: 20

To start, let's select the mode. The mode is the number that appears most frequently in a set of numbers. In this case, the mode is 21. So, we need to include 21 at least twice in our set.

One possible set of numbers satisfying the mode requirement is: {21, 21}

Next, let's consider the median. The median is the middle number when the set is arranged in ascending or descending order. In this case, the median is 24. Since 21 is already included twice in the set, we need to add two more numbers to our set before 24 to maintain the median.

The set can be: {20, 20, 21, 21, 24}

Now let's move on to the maximum. The maximum is the highest value in the set. The maximum number is given as 35. Therefore, we can add 35 to our set.

The set becomes: {20, 20, 21, 21, 24, 35}

Finally, let's consider the range. The range is the difference between the maximum and minimum values in a set. The range is given as 20, which means the minimum value is 15 in this case. To have a range of 20, we need to add 15 to our set.

The final set of numbers satisfying all the landmarks is: {15, 20, 20, 21, 21, 24, 35}

In this way, you can create a set of 7 numbers with the given landmarks.
