Answers

Answer 1

Answer:

0.0058 or 0.58%

Explanation:

We can use a normal approximation to the binomial distribution to find the probability that less than 80% of the sample would report eating healthily the previous day.

First, we need to calculate the mean and standard deviation of the binomial distribution.

The mean is given by:

mean = (sample size) x (proportion of success) = 675 x 0.78 = 522.5

The standard deviation is given by:

standard deviation = sqrt((sample size) x (proportion of success) x (proportion of failure)) = sqrt(675 x 0.78 x 0.22) = 7.7

Then we can use the standard normal distribution (z-score) to find the probability of getting a sample proportion less than 0.8:

z = (80% - 78%) / (standard deviation / sqrt(675)) = (0.02 - 0.78) / (7.7/sqrt(675)) = -2.6

Using a standard normal table, we can find that the probability of getting a z-score less than -2.6 is about 0.0058 or 0.58%.

So the approximate probability of getting a sample proportion less than 80% is 0.0058 or 0.58%

A plane crashes on the border of the USA and Canada where do you bury the survivors?

Answers

Survivors are not to be buried.

Who are survivors?

The survivors of accidents are those that escape death or being killed during the course of the events. They could be totally unhurt or injured in a non-fatal way and get back to their healthy self with time.

Unlike survivors, dead bodies are considered a nuisance to the environment. Hence, they are quickly buried before they start decomposing and become a source of diseases to the populace.

In other words, survivors are not usually buried in any sane society. Only those that are dead are buried.

So, if a plane crashes on the border of the USA and Canada, burying the survivors does not come up at all. That would be a total aberration.

Answers

Answer:

Advertising is any paid form of communication from an identified sponsor or source that draws attention to ideas, goods, services or the sponsor itself. Most advertising is directed toward groups rather than individuals, and advertising is usually delivered through media such as television, radio, newspapers and, increasingly, the Internet. Ads are often measured in impressions (the number of times a consumer is exposed to an advertisement).

Advertising is a very old form of promotion with roots that go back even to ancient times. In recent decades, the practices of advertising have changed enormously as new technology and media have allowed consumers to bypass traditional advertising venues. From the invention of the remote control, which allows people to ignore advertising on TV without leaving the couch, to recording devices that let people watch TV programs but skip the ads, conventional advertising is on the wane. Across the board, television viewership has fragmented, and ratings have fallen.

Print media are also in decline, with fewer people subscribing to newspapers and other print media and more people favoring digital sources for news and entertainment. Newspaper advertising revenue has declined steadily since 2000.[1] Advertising revenue in television is also soft, and it is split across a growing number of broadcast and cable networks. Clearly companies need to move beyond traditional advertising channels to reach consumers. Digital media outlets have happily stepped in to fill this gap. Despite this changing landscape, for many companies advertising remains at the forefront of how they deliver the proper message to customers and prospective customers.

The Purpose of Advertising

Advertising has three primary objectives: to inform, to persuade, and to remind.

Informative Advertising creates awareness of brands, products, services, and ideas. It announces new products and programs and can educate people about the attributes and benefits of new or established products.

Persuasive Advertising tries to convince customers that a company’s services or products are the best, and it works to alter perceptions and enhance the image of a company or product. Its goal is to influence consumers to take action and switch brands, try a new product, or remain loyal to a current brand.

Reminder Advertising reminds people about the need for a product or service, or the features and benefits it will provide when they purchase promptly.

What issues may arise if nominal gross domestic product was used instead of real gross domestic product?

Answers

Answer: See explanation

Explanation:

Real gross domestic product is simply refered to the economic output of a particular country which has been adjusted for price changes as inflation was taken into consideration.

Nominal gross domestic product is the measurement of the gross domestic product of a particular country which makes use of current prices, and isn't inflation adjusted.

The issue that may arise when nominal gross domestic product was used instead of real gross domestic product is that the nominal GDP leads to the inflation of the growth figure in the economy. This is because the nominal GDP doesn't take inflation into effect.

This leads to the misleading of the GDP since there'll be an overstatement of the GDP even though it was actually a rise in the inflation rate for the particular economy.

How long was each sprinkler used

Let x represent  how long each sprinkler was used

Hence:

40(x)+15(55-x)=1575

40x+825-15x=1575

Collect like terms

40x+-15x=1575-825

25x=750

Divide both side by 25x

x=750/25
