Prove that

cos 5x/sin17x-sin3x=-sin2x/cos10x" alt="cos 9x-cos 5x/sin17x-sin3x=-sin2x/cos10x" align="absmiddle" class="latex-formula">

Cos9x - cos5x = -2sin2x.sin7x
sin17x - sin3x = 2sin7x.cos10x
so f(x) = $\frac{-2sin2x.sin7x}{2sin7x.cos10x}$ = $\frac{-sin2x}{cos10x}$

The following data show the prices of different types of outfits at a store: $2, $2, $28, $26, $25, $27, $25, $27, $26, $28, $30

arlik [135]

2, 2, 25, 25, 26, 26, 27, 28, 28, 30

Minimum: 2

Maximum: 30

Median: 26

Lower quartile: 25

Upper quartile: 28

The box plot will have its left tail longer than the right tail because a few exceptionally low prices make the distribution skewed to the left.
