Check the picture below
solve for "x"
since we know the two smallest sides for EFGH are 9 and 18, 9 is the smallest of all, and 18 is the next small
thus, for the the quadrilateral ABCD, the smallest is "x" and the next small is given, is 12, since that's smaller than 16 or 24
The distance is increasing at a rate that is the speed of the plane multiplied by the cosine of the angle between its flight path and the direct line to the radar station. That cosine is 4/√(3²+4²) = 4/5, so the distance is increasing at
440 mi/h × 4/5 = 352 mi/h
Area = base x height
28 x 42 = 1176
The answer to the question
Answer:
Interquartile Range
The interquartile range of an observation variable is the difference of its upper and lower quartiles. It is a measure of how far apart the middle portion of data spreads in value.
Interquartile Range = U pper Quartile − Lower Quartile
Problem
Find the interquartile range of eruption duration in the data set faithful.
Solution
We apply the IQR function to compute the interquartile range of eruptions.
> duration = faithful$eruptions # the eruption durations
> IQR(duration) # apply the IQR function
[1] 2.2915
Answer
The interquartile range of eruption duration is 2.2915 minutes.
