There is an average of 22.455 employees at 22 office furniture dealers in a major metropolitan area, with a standard deviation o
valina [46]

Answer:

The 99 percent confidence interval for the true mean number of full-time employees at office furniture dealers is (12.288, 32.622).

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.99}{2} = 0.005

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.005 = 0.995, so z = 2.575

Now, find M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 2.575*\frac{18.52}{\sqrt{22}} = 10.167

The lower end of the interval is the mean subtracted by M. So it is 22.455 - 10.167 = 12.288

The upper end of the interval is the mean added to M. So it is 22.455 + 10.167 = 32.622

The 99 percent confidence interval for the true mean number of full-time employees at office furniture dealers is (12.288, 32.622).

How to solve -(y+-6)=-1
katrin [286]

- (y - 6) = - 1

Distribute the negative

- y + 6 = 1

Subtract 6

from both sides of the equation

Simplify

Subtract the numbers

- y = - 7

Divide both sides of the equation by the same term

- y = - 7

- y = - 7

-1      -1

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

=

A ship travels 62 km on a bearing of 12 degrees, and then travels on a bearing of 102 degrees for 111 km. Find the distance from
Zigmanuir [339]
A bearing is an angle measured from the North.

The diagram should be something like that given above. (Note that the angles may not be measured accurately).

The diagram is drawn as follows:
1. The ship travels on a bearing of 12 degrees from the North line first so measure 12 degrees from the North line.
2. Then from that point, after it travels 62 km, the ship goes on a bearing of 102 degrees so draw another imaginary north line, and measure 102 degrees from it.

The diagram now takes shape of a triangle. Use the cosine rule to find the missing side (marked x km). Here is how I do the cosine rule:

First find the missing angle at the top of the triangle: 180 - 102 = 78 degrees. (Angles on a straight line add up to 180 degrees)

So, remember this formula:

Suppose the missing side is: c^2.

c^2 = a^2 + b^2 - (2ab cosC)

If you look at the diagram above, the angle C and the sides a, b, and c have been marked.

Use the formula given above and find the side c (that's the question you have been asked).

c^2 = 62^2 + 111^2 - (2(62)(111) cos 78)

c^2 = ANS (a very long number - better if you don't round off a number in the middle of an equation)

c = square root of ANS (following the rules of Algebra)

c = 115.34 km or simply 115 km

So the distance between the starting point to the end of the trip is 115 km.
