Answer:
1 + cosa sina
Step-by-step explanation:
cos³a - sin³a ← is a difference of cubes and factors in general as
a³ - b³ = (a - b)(a² + ab + b²) , then
cos³a - sin³a
= (cosa - sina )(cos²a + cosa sina + sin²a)
= (cosa - sina)(1 + cosa sina) [ sin²a + cos²a = 1 ]
Then
= ← cancel (cosa - sina) on numerator/ denominator
= 1 + cosa sina
Answer: The interquartile range= 12
Step-by-step explanation:
From the given the lower quartile = 42
the middle quartile = 49
The upper quartile = 54
We know that the interquartile range is given by:=-
Interquartile range= upper quartile- lower quartile or
⇒
Hence, the interquartile range of the data displayed in this box-and-whisker plot is 12.
