Final answer:
The mean is 12.6, the median is 12, and there is no mode in the set of numbers 12, 9, 17, 15, and 10.
Step-by-step explanation:
In order to find the mean, median, and mode of 12, 9, 17, 15, and 10, we need to first understand what each of these terms represent.
The mean is the average of a set of numbers, calculated by adding up all the numbers and then dividing by the total number of numbers.
The median is the middle value in a set of numbers when they are arranged in numerical order.
The mode is the number that appears most frequently in the set of numbers.
To find the mean, add up all the numbers: 12 + 9 + 17 + 15 + 10 = 63.
Then, divide the sum by the total number of numbers, which is 5 in this case. So, the mean is 63 / 5 = 12.6.
To find the median, arrange the numbers in numerical order: 9, 10, 12, 15, 17.
There are 5 numbers, so the median is the middle number, which is 12.
To find the mode, observe which number appears most frequently.
In this case, no number appears more than once, so there is no mode.
