In an natural observational study investigators observe subjects and measure variables of interest without assigning treatments to the subjects

In an experimental study (inferential stat), data are used to make generalizations about a population based on a sample.

Hence the 1st question is an experimental.

Veseljchak [2.6K]

Answer:

First an investigating team should be formed to investigate the case, they should find evidence against the culprit. They should investigate whether he has stole funds only or he has some private or secret information. The case should be examined closely and decision should be taken that whether to involve police in the case or just handle it by their own. In severe cases it is important to involve police. Depending upon the case, maybe just firing the employee is enough and no legal action would be taken.

Answer:

1) The angle would be 150 degrees

a) coordinates would be ( -\frac{\sqrt{3}}{2}, \frac{1}{2} )

b) Trigonometric ratios:

sin:  \frac{1}{2}

cos: -\frac{\sqrt{3}}{2}

tan: -\frac{\sqrt{3}}{3}

csc: 2,  

sec: -\frac{2\sqrt{3}}{3}

cot: \sqrt{3}

Explanation:

\frac{17\pi }{6} simplifys to \frac{5\pi }{6} which has a reference angle of \frac{\pi }{6}. We can take the coordinates of \frac{\pi }{6} and make the x value negative to find the correct coordiantes. Then, using those coordinates, plug the into the trigonomic equations.

For example, sin in opposite/hypotenuse. So sin = 1/2 divided by 1. Then you can find the rest of the equations that way.

cos= adjacent/hypotenuse

tan= sin/cos

csc= hypotenuse/opposite

sec= hypotenuse/adjacent

cot= cos/sin
