Answer:
It can be written 60 different three digit numbers.
Step-by-step explanation:
For, calculate how many different three digit numbers can be written, we can use the rule of multiplication as:
5 * 4 * 3 = 60
1st digit 2nd digit 3rd digit
Taking into account that there is no repeating digits, we have 5 options for the first digits, this options are the number 5, 6, 7, 8 or 9. Then, we have 4 options for the second digit and then we have 3 options for the third digit.
So, there are 60 different three digit numbers that we can create with the set 5, 6, 7, 8, 9 without any repeating digits.

The number of Customers that visited the store during the eight hour if the median number of customers didn't change is; C: 20
We are given the data representing the first seven hours as; 12, 15, 18, 20, 23, 23, 28. Here; n=7
Thus;
Median = (n + 1)/2 = (7 + 1)/2
Median = 4th term
Thus, the median is 20.
When one data is added, n = 8. Thus;
Median will be the average of the 4th and 5th term. Since the median does not change, it means that the median number of customers per hour is still 20.
