The equivalent ratios are 3 to 5, 24 to 40, and 6 to 10.

Ratios are equivalent when they can be simplified down to the same ratio, for example 2 to 4 simplifies to 1 to 2 (by dividing by 2), and so does 3 to 6 (by dividing by 3), so these are equivalent. We can find answers by first simplifying the original ratio 12 to 20, which we can do by finding common factors and dividing by them:

12 to 20

÷ 2

6 to 10 (here we have found one answer)

÷ 2

3 to 5 (and here is another answer)

We then get 24 to 40 by multiplying the original ratio by 2, so:

12 to 20

× 2

24 to 40

I hope this helps! Let me know if you have any questions :)

Given sec(theta)= 5... find cot(90-theta)
Mumz [18]
\sec(\theta)=\frac{1}{\cos(\theta)}
\\
\\\cos(\theta)=\frac{1}{\sec(\theta)}=\frac{1}{5}
\\
\\ \sin^2\theta+\cos^2\theta=1
\\
\\\sin\theta= \sqrt{1-\cos^2\theta}= \sqrt{1-( \frac{1}{5})^2 }  = \sqrt{1- \frac{1}{25} } = \sqrt{ \frac{25}{25} -\frac{1}{25} }=\frac { \sqrt{24}}{5} 
\\
\\ \cot(90^o-\theta)=\tan{\theta}= \frac{\sin\theta}{\cos\theta} = \frac{\frac { \sqrt{24}}{5} }{ \frac{1}{5} } = \sqrt{24} = \sqrt{4\times6}=2 \sqrt{6}

An investigative bureau uses a laboratory method to match the lead in a bullet found at a crime scene with unexpended lead cartr
Basile [38]

Answer / Step-by-step explanation:

In this exercise, we know that the agency collected 1,829 bullets which according to the agency, all came from different source.

The number of pair of bullet is :

         (1,829) = 1, 829 ! / 2! ( 1,829 - 2 ) = 1, 829 x 1,828 x 1827 ! / 2 x 1 x 1,827

          (   2   )

                   = 6, 108,413,724 / 3654

                   = 1671,706.

Also, we know that the agency found 658 matches. According to this, the chance of false positive ( that is, the agencies find a match but the bullets are from two different source ) is

   P (False positive ) = 658 / 671,706

                                   = 0.000979.

The probability is small to an extent, therefore, we should have confidence in the agency forensic report and evidence
