can some tell me all the answers i am having really bad trouble doing this
#1 is: b. 56 has 1. 57has 3.. 58 has 2. 59 has 1. 62 has 1. and 64 has 1
#2 is b to
#3 is d
also #4 is c
To find the mean, median, mode, and range of a data set, you can follow these steps:
1. Mean: Add up all the numbers in the data set and then divide the sum by the total number of numbers in the set. This will give you the mean (or average) value.
In this case, the data set is: 15, 16, 21, 23, 25, 25, 25, 39.
Add all the numbers together: 15 + 16 + 21 + 23 + 25 + 25 + 25 + 39 = 189.
There are 8 numbers in the data set, so divide the sum by 8: 189 ÷ 8 = 23.625. Therefore, the mean is 23.625.
2. Median: Arrange the numbers in the data set in ascending order from smallest to largest. Then find the middle value of the set.
In this case, the data set is already in ascending order: 15, 16, 21, 23, 25, 25, 25, 39.
Since there are 8 numbers in the data set, the middle value will be the average of the two middle numbers. In this case, the two middle numbers are 21 and 23. So, the median is (21 + 23) ÷ 2 = 22.
3. Mode: The mode refers to the number(s) that occur(s) most frequently in the data set.
In this case, the number 25 occurs most frequently, appearing three times, while all the other numbers appear only once. Therefore, the mode is 25.
4. Range: The range is the difference between the largest and smallest values in the data set.
In this case, the smallest value is 15 and the largest value is 39. So, the range is 39 - 15 = 24.
Therefore, for the data set 15, 16, 21, 23, 25, 25, 25, 39, the mean is 23.625, the median is 22, the mode is 25, and the range is 24.
