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.

Answer:
The y intercept of the line is (0, -14).
Step-by-step explanation:
we are given the equation
y + 11 = -2(x + 1.5)
The y-intercept of the line is the point where x = 0,
Substituting x = 0 into the expression:
y + 11 = -2(0 + 1.5)
y + 11 = -0 – 3
y + 11 = -3
y = 11 – 11 = -3 – 11
y = -14
Thus, The y intercept of the line is (0, -14).
