Determine the volume of the three-dimensional<br> figure.

Finger [1]

Answer:

288 cubic inch

Step-by-step explanation:

Top and bottom bases are trapezoid of same dimensions and height is 4 in.

Therefore,

$volume \\ = area \: of \: trapezoid \times height \\ = \{\frac{1}{2} (16 + 8) \times 6 \} \times 4 \\ = 24 \times 6 \times 2 \\ = 48 \times 6 \\ = 288 \: {in}^{3} \\$

densk [106]

Answer: 24

Step-by-step explanation:

From the question, we are informed that Micah is buying items for a party and that there are 6 cups in a package and 8 plates in a package.

We are further told that he wants to have the same amount of each item. The least number of packages of cups he needs to buy would be calculated by finding the least common multiple of 6 and 8.

Multiples of 6 = 6, 12 18, 24, 30

Multiples of 8 = 8, 16, 24, 32, 40

The answer is 24 cups

A sales and marketing management magazine conducted a survey on salespeople cheating on their

Alenkinab [10]

Answer:

The 95% confidence interval estimate of the population proportion of managers who have caught salespeople cheating on an expense report is (0.5116, 0.6484).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

In the survey on 200 managers, 58% of the managers have caught salespeople cheating on an expense report.

This means that $n = 200, \pi = 0.58$

95% confidence level

So $\alpha = 0.05$ , z is the value of Z that has a pvalue of $1 - \frac{0.05}{2} = 0.975$ , so $Z = 1.96$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.58 - 1.96\sqrt{\frac{0.58*0.42}{200}} = 0.5116$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.58 + 1.96\sqrt{\frac{0.58*0.42}{200}} = 0.6484$

The 95% confidence interval estimate of the population proportion of managers who have caught salespeople cheating on an expense report is (0.5116, 0.6484).
