"A number" means the unknown.
This is our problem: 3 + 6 / N
Answer:
1/6 and 16.67
Step-by-step explanation:
Add all the marbles, you get 12.
There's 2 out of 12 yellow marbles so you get 2/12
2/12 simplified to 1/6
So 1/6 is the probability as a fraction
Now to get the percentage just divide 100 by 6.
100/6 equals 16.67
Since it's 1/6 we multiply that by one
16.67 times 1 equals 16.67
Using the median concept, it is found that the interquartile range of Sara's daily miles is of 21 miles.
<h3>What are the median and the quartiles of a data-set?</h3>
- The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.
- The first quartile is the median of the first half of the data-set.
- The third quartile is the median of the second half of the data-set.
- The interquartile range is the difference of the quartiles.
The ordered data-set is given as follows:
65, 72, 86, 88, 91, 93, 97
There are 7 elements, hence the median is the 4th element, of 88. Then:
- The first half is 65, 72, 86.
- The second half is 91, 93, 97.
Since the quartiles are the medians of each half, the have that:
- The first quartile is of 72 miles.
- The third quartile is of 93 miles.
- The interquartile range is of 93 - 72 = 21 miles.
