We are given with the expression arctan(-sqrt(3)) and asked to evaluate it. In this case, we can use a calculator or the rule of common triangles to answer this question. the value of <span>arctan(-sqrt(3)) is -60. Since negative tan is found in 2nd and 4th quadrant, the angles are 180-60 or 120 degrees and 360-60 or 300 degrees.</span>
Answer:
The margin of error for the 94% confidence interval is 0.6154.
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population mean is:

The margin of error of this interval is:

The critical value of <em>z</em> for 94% confidence level is, <em>z</em> = 1.88.
Compute the margin of error for the 94% confidence interval as follows:


Thus, the margin of error for the 94% confidence interval is 0.6154.
Answer:
Width
units
Length
units
Step-by-step explanation:
The rectangle has an area of 
The width of the rectangle is equal to the greatest common monomial factor of
and
Find this monomial factor:

Hence, the width of the rectangle is
units.
The area of the rectangle can be rewritten as

The area of the rectangle is the product of its width by its length, then the length of the rectangle is
units.
