Answer: The correct option is (A) 121.25 feet.
Step-by-step explanation: Given that a parking lot is 272.5 feet long and 151.25 feet wide.
We are to find how much longer is the lot than it is wide.
Let, 'l' and 'w' be the length and width of the parking lot.
Then, l = 272.5 feet and w = 151.25 feet.
We have,
Therefore, the length is 121.25 feet longer than the width.
Thus, (A) is the correct option.

Given:
The data values are
11, 12, 10, 7, 9, 18
To find:
The median, lowest value, greatest value, lower quartile, upper quartile, interquartile range.
Solution:
We have,
11, 12, 10, 7, 9, 18
Arrange the data values in ascending order.
7, 9, 10, 11, 12, 18
Divide the data in two equal parts.
(7, 9, 10), (11, 12, 18)
Divide each parenthesis in 2 equal parts.
(7), 9, (10), (11), 12, (18)
Now,
Median =
=
=
Lowest value = 7
Greatest value = 18
Lower quartile = 9
Upper quartile = 12
Interquartile range (IQR) = Upper quartile - Lower quartile
= 12 - 9
= 3
Therefore, median is 10.5, lowest value is 7, greatest value is 18, lower quartile 9, upper quartile 12 and interquartile range is 3.
