Answer:
Mean- 17.8 Median- 16 Mode- 17.8
Step-by-step explanation:
1. Put the numbers in ascending order.
1, 7, 7, 13, 15, 17, 23, 25, 28, 42
2. Look for the median. The median is the number located in the middle of a set of numbers. In this case, the median is going to be between 15 and 17 because they are both in the middle. This means that the median will be 16.
1, 7, 7, 13, 15, 17, 23, 25, 28, 42
3. Find the mode. The mode is the number you see the most in a set of numbers. In this case, there are two 7's so 7 is the mode of this set.
1, 7, 7, 13, 15, 17, 23, 25, 28, 42
4. Find the mean. The mean is the overall average of a set of numbers. To find the average, find the sum of all the numbers in the set and divide it by the number of integers there are. In this case, there are ten integers, so we'll find the sum (178) and divide it by 10 to get a mean of 17.8.
[tex]\frac{1+7+7+13+15+17+23+25+28+42}{10}[/tex] = 17.8
5. Find the range. The range is basically the difference between the lowest and highest values in a set of numbers. The lowest number is 1 and the highest is 42. So, we'll subtract the two to get a range of 41.
1, 7, 7, 13, 15, 17, 23, 25, 28, 42
42 - 1 = 41
