\dfrac{\sin\theta\cdot\cot\theta}{\tan\theta\cdot\cos\theta}=\dfrac{\sin\theta}{\cos\theta}\cdot\dfrac{1}{\tan\theta}\cdot\cot\theta=\tan\theta\cdot\dfrac{1}{\tan\theta}\cdot\cot\theta=\boxed{\cot\theta}

8.

\dfrac{\cot\theta}{\cos\theta}\cdot\dfrac{\sin\theta\cdot\cos^2\theta}{1-\cos^2\theta}=\dfrac{\cot\theta}{\cos\theta}\cdot\dfrac{\sin\theta\cdot\cos^2\theta}{\sin^2\theta}=\cot\theta\cdot\dfrac{\cos\theta}{\sin\theta}=\cot\theta\cdot\cot\theta=\\\\\\=\boxed{\cot^2\theta}

stellarik [79]

Answer:

The value is  \r p  =  2.9\%

Step-by-step explanation:

From the question we are told that

   The  number of singers is  N  =  1542

   The  sample  size is  n  =  650

    The  number the number of singers who are professional is k =  19

The  proportion of professional singers is mathematically represented as

       p  =  \frac{k}{n}

=>      p  =  \frac{19}{650}

=>    p  =  0.029

The  percentage estimate of singers who are professional is

      \r p  =  100 * 0.029

       \r p  =  2.9\%
