Answer:The mode is 21.

The mode of a set of numbers is the number that appears most frequently. In this case, the number 21 appears twice, which is more frequent than any other number in the set, making 21 the mode.

Explanation

The mode of a set of numbers is the number that appears most frequently. In this case, the number 21 appears twice, which is more frequent than any other number in the set, making 21 the mode.

9. What is the median of 45,12,21,23,65,74,71,85?

The median is 45,71.

Answer:The median is 23,65.

The median is 21,74.

The median is 12,85.

To find the median, arrange the numbers in ascending order: 12, 21, 23, 45, 65, 71, 74, 85. Since there are 8 numbers, the median will be the average of the middle two numbers, which are 23 and 65.

11. What is the range of the following set of numbers: 6, 8, 5, 9, 10, 20, 36, 85, 2, 56?

Answer:The range is 83.

The range is 75.

The range is 80.

The range is 90.

To find the range of a set of numbers, subtract the smallest number from the largest number. In this case, the smallest number is 2 and the largest number is 85. 85 - 2 = 83, hence the range is 83.

Explanation

To find the range of a set of numbers, subtract the smallest number from the largest number. In this case, the smallest number is 2 and the largest number is 85. 85 - 2 = 83, hence the range is 83.

12. What is the mode of 14,51,52,85,96,31,96,4,5?

Answer:The mode is 96.

The mode is 51.

The mode is 4.

The mode is 31.

In statistics, the mode is the value that appears most frequently in a data set. In this case, the number 96 appears twice, which is more than any other number in the set, making it the mode.

Explanation

In statistics, the mode is the value that appears most frequently in a data set. In this case, the number 96 appears twice, which is more than any other number in the set, making it the mode.

13. What is the mean of 96, 25, 48, 75, 64, 12, 34, 5?

Answer:The mean is 44.875.

The mean is 37.2.

The mean is 68.25.

The mean is 58.5.

To find the mean of a set of numbers, you add up all the numbers and then divide the sum by the total number of values. In this case, the sum of 96, 25, 48, 75, 64, 12, 34, and 5 is 349. Dividing 349 by 8 (the total number of values) gives us a mean of 44.875.

Explanation

To find the mean of a set of numbers, you add up all the numbers and then divide the sum by the total number of values. In this case, the sum of 96, 25, 48, 75, 64, 12, 34, and 5 is 349. Dividing 349 by 8 (the total number of values) gives us a mean of 44.875.
