Answer: Ellipse

This cross section is not parallel to the circular base, so we get a stretched out circle of sorts. In other words, we get an ellipse.

The Reunion Tower is one of the most recognizable landmarks in Dallas, Texas due to the giant sphere that sits atop the structur

ValentinkaMS [17]

The volume of a sphere uses the following formula:

$V = \frac{4}{3}\pi r^{3}$

Because the question asks to use 3.14 in place of pi, the formula will now look like this:

$V = (\frac{4}{3})(3.14)r^{3} = 4.18\overline{66} r^{3}$

We are given a diameter of 118 feet. The radius is half of the diameter, so divide the diameter by 2 to find the radius:

$118 \div 2 = 59$
$r = 59$

Plug this value into the formula, and solve with a calculator:

$4.18\overline{66} \times 59^3 = 4.18\overline{66} \times 205379 = 859853.413$

Although our result is one cubic foot off, the answer is <span>A. 859,852ft^3.

(859,852 is the result if the constant in the given formula is 4.18666, but the result with infinitely repeating numbers is 859,853.)</span>

Kitchen salespersons average $10,000 per week in sales. Manager proposes a compensation plan with new selling incentives. Manage

Oxana [17]

Answer:

a) The alternative hypothesis has to reflect the claim that the research want to test. In this case, we want to test if there is enough evidence that the incentives increase the average sales per salesperson.

That is, if the average sales are significantly higher than $10,000 per salesperson.

The null hypothesis will state that the average sales per salesperson is not significantly higher than $10,000, representing the base case.

Then, we can write the hypothesis as:

$H_0: \mu=10,000\\\\H_a: \mu>10,000$

b) A Type I error happens when a true null hypothesis is rejected.

In this case, it would represent concluding that the incentive program is effective in increasing sales when it is not really the case.

The significative difference would be only due to chance and not to a real difference.

c) A Type II error happens when a false null hypothesis failed to be rejected.

In this case, it would represent that the sample statistic gives no enough evidence to support the claim that the incentive program is effective, although it is, in fact, effective. The conclusion will be, erroneously, that the program of incentives is not effective.
