To determine the standard deviation of the number of people who suffer from insomnia, you need to use the following formula:
= sqr of npq

= √10,200 people in the community x 0.6 people who suffer from insomnia x 0.91 = ?
= √10,200 x 0.6 x 0.91 = <span>√55.143 = 7.43 

= 7.43</span>

enot [183]

Answer:

The correct answer is d. planned value

Explanation:

Among project managers, the Earned Value is one of the most demanded requirements of management tools. When we talk about it, we refer to Earned Value Management (EVM), a series of parameters that advise on the operation of the project based on a planning. The Earned Value will inform us of the cost and time deviations of the project.

Over the last four years, a stock has had an arithmetic average return of 8.8 percent. Three of those four years produced return
m_a_m_a [10]

Answer:

Geometric Average return = 7.83%

Explanation:

First we need to find the missing value of data using Arithmetic mean formula

Arithmetic Mean = Sum of value / No of values

8.8% = Sum of Values / 4

Sum of Values = 8.8% x 4

Sum Values = 35.2%

Using Sum of Values we minus the remaining values in order to get the missing value of the data.

35.20% - 16.3% - 10.2%-(14.1%) = 22.80%

In order to get Geometric mean value we use geometric mean formula

G.M = 4 Sqrt(16.3% x 10.2% x -14.1% + 22.80%)

Geometric Mean = 7.83%

So why it is a ration decision to make sure the marginal benefits outweighs the marginal costs? (Be detailed, you can use exampl
Rzqust [24]

Answer:

For the business to make profits

Explanation:

Marginals revenue is the additional income realized from the sale of an extra unit. It is the revenue that a firm will gain by selling one more unit of a product or service.

Marginal cost is the expense incurred in the production of one more unit of a product.  A business compares marginal revenue to marginal cost to decide if it will cease or continue with production and selling activities.

For a business to continue selling and make profits, marginal revenue must be greater than the marginal cost. In other words, the revenue realized by selling one extra unit must exceed the cost of producing that item. Selling one more unit when the marginal cost is more than the marginal revenue will result in a loss.

If the marginal revenue from a computer is $40 and the marginal cost is $50,  selling on extra computer results in a loss of $10. But if the marginal revenue from the same computer is $60, the sale on one more unit will be a gain of $10.

Sauron [17]

The correct answer is A) alignment.

After spending months finalizing a marketing plan, the lead marketing manager presents it to the entire company. It soon becomes clear that the budget given in the plan is far lower than the marketing team had determined it would need. This mistake is likely a result of a lack of alignment.

This means that the marketing manager did not respect the parameters originally indicated. His numbers did not align with the necessities of the plan, which means that he did not take into consideration some important factors that at the end, affected the end result of the budget.
