The table lists physical characteristics for five caves in the Karst Belt.

CaveDepth (meters)Volume (million m^3)Floor area (km^2)Mapped passage length (km)
Azur1804024.055
Boreal72012058.088
Cinder79018051.0120
Dusk91020047.5260
Ember128060073.0160

For each of the following statements, select Yes if it must be true based on the table provided; otherwise select No.

1) The cave with the largest mapped passage length also has the smallest floor area.

The largest mapped passage belongs to Dusk. The floor area of Dusk = 47.5 Km^2 which is greater than 24.0 ( the smallest floor area belonging to Azur).

Hence, No.

2) Cinder has the median value across all four listed physical characteristics (depth, volume, floor area, mapped passage length)

Lets arrange the values in ascending order for each category.

Depth median = Cinder (790).

Volume median = Cinder (180).

Floor area median = Cinder (51.0).

Mapped passage Length median = Cinder (120).

Hence, Yes.


3) The range of depths among the five caves is greater than 1000 meters.

Range of depths = 1280 - 180 = 1100 , which is GREATER than 1000 metres. Hence, Yes.

1. The cave with the largest mapped passage length is Dusk with the value 260 km, but has the floor area of 47.5 km^2 which isnt the smallest (24.0). Therefore No.
2. Depth = 790, Volume = 180, Floor area = 51, mapped passage length = 120, all median in respective characteristic. Therefore Yes.
3. Min value = 180, max value = 1280, range = 1100. Therefore yes.

1) The cave with the largest mapped passage length also has the smallest floor area. -->No ( Not least but second least value i.e 47.5)
2) Cinder has the median value across all four listed physical characteristics (depth, volume, floor area, mapped passage length) ---> yes ( 790,180,51, 120)
3) The range of depths among the five caves is greater than 1000 meters. ---> 1280-180 -->1100>1000 --> yes

1. The cave with the largest mapped passage length also has the smallest floor area.

Sort the Largest mapped passage length, and we see that Dusk has 260 km, but the smallest floor area is 24.0 km^2 of Azur. Hence, No.

2 Cinder has the median value across all four listed physical characteristics (depth, volume, floor area, mapped passage length).

By sorting each column and noting the middle value for depth, volume, floor area, and mapped passage length, the median value which is 3rd position in 5 listing in each case belongs to Cinder. Hence, yes.

3. The range of depths among the five caves is greater than 1000 meters.

By looking at depth column, we see that max is 1280 and min is 180, and range is noting but difference of max and min, so 1280 − 180 = 1100 mtrs, which is greater than 1000 mtrs. Hence, Yes.

Hope it helps
