Using the following set of data, calculate the lower quartile, the upper quartile, and the interquartile range.20, 22, 25, 28, 2
madreJ [45]

Answer:

The lower quartile is 23.5

The upper quartile is 32.5

The interquartile range is 9

Step-by-step explanation:

The given data set is 20, 22, 25, 28, 29, 30, 32, 33, 34.

The data set is already sorted in ascending order.

The middle number of this data set is called the median.

Therefore the median is 29.

The median divides the data set into two halves.

The lower half is

20, 22, 25, 28

The median of the lower half is the lower quartile.

Q_1 =  \frac{22 + 25}{2}  =  \frac{47}{2}  = 23.5

The upper half is 30, 32, 33, 34

The median of the upper half is the upper quartile.

Q_3= \frac{33 + 32}{2}  = 32.5

The interquartile range is given by

IQR=Q_3-Q_1 \\ IQR=32.5 - 23.5 = 9

A tree casts a 20 foot long shadow. Frank is 6 feet tall and while standing next to the tree he casts a shadow that is 4 foot lo
galben [10]
20 feet Any height. When the Sun is low, in the morning or evening close to the horizon, even a short object will cast a long shadow. When the Sun is directly overhead (at noon between the Tropic of Capricorn and the Tropic of Cancer) objects cast no shadow. If you tell us your location and the time you are measuring then there would be a possibility of calculating an answer. At noon on one of the equinoxes in Montpelier VT (or anywhere at the latitude of 45 degrees <span>north or 45 degrees south) a 50 foot tall tree will cast a 50 foot shadow.

an office building is 5 times as tall as a house. if the difference in their height is 100, how tall is the building
nalin [4]

Answer: 20

20 since you have to divide 100 by 5 which equals 20 since you have to use the inverse operation of multiplication which is division.

Hope this helps!
