What are the minimum, first quartile, median, third quartile, and maximum of the data set?
2 answers:
Answer:
Minimum = 4
First quartile = 6.5
Median = 13.5
Third quartile = 19
Maximum = 20
Step-by-step explanation:
1. Order the data set from the smallest to the largest number:
4 4 9 9 18 18 20 20
2. Find the minimum:
The minimum of the data set is the smallest number
Minimum = 4
3. Find the maximum:
The maximum of the data set is the largest number
Maximum = 20
4. Find the median:
As the data set has an even number of data, the median is the average between 9 and 18, that are the two data in the middle:
Median =
Median = 13.5
5. Find the first quartile:
The median divide the data set between two groups:
4 4 9 9 Median=13.5 18 18 20 20
The first quartile is the average of the two data in the middle of the first group:
4 4 9 9
First quartile =
First quartile = 6.5
6. Find the third quartile:
The third quartile is the average of the two data in the middel of the second group:
18 18 20 20
Third quartile =
Third quartile = 19

The unit rate you're trying to find is pages per day(or p/d), so the equation needs to have both a unit for pages and for days.
The equation we have is:
If they read 5,249 <em>pages</em>, then we can include the unit for pages in the equation.
Since we also know that <em>d</em> is the number of days it took, you can replace <em>d</em> with days.
The equation becomes:
Now that we have one variable, we can solve for <em>p/d</em>:
Thus it took them 181 days to read it all.
If Johnny read 5,249 pages over 181 days and the unit rate is pages per day(p/d), then the equation for finding <em>p/d</em> is:
Johnny read 29 pages per day.
