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%
The Jenkins family and the Moore family each used their sprinklers last summer. The water output rate for the Jenkins family's sprinkler was per hour. The water output rate for the Moore family's sprinkler was per hour. The families used their sprinklers for a combined total of hours, resulting in a total water output of . How long was each sprinkler used?
How long was each sprinkler used is 30 hours.
How long was each sprinkler usedLet 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
x=30 hours
Therefore the Jenkins used the sprinklers for 30 hours while Green's used it for 25.
The complete question is:
The Jenkins family and the Moore family each used their sprinklers last summer. The water output rate for the Jenkins family's sprinkler was 40l per hour. The water output rate for the Moore family's sprinkler was per 15l hour. The families used their sprinklers for a combined total of 55 hours, resulting in a total water output 1575 of .

Which of the following pairs of angles is not necessarily congruent
Answer:
E. [tex]\angle 3[/tex] and [tex]\angle 5[/tex].
Explanation:
According to the figure, we have the following conclusions:
1) [tex]\angle 1[/tex] and [tex]\angle 2[/tex] are vertical opposite angles. ([tex]m \angle 1 = m \angle 2[/tex])
2) [tex]\angle 2[/tex] and [tex]\angle 3[/tex] are internal alternate angles. ([tex]m \angle 2 = m\angle 3[/tex])
3) [tex]\angle 2[/tex] and [tex]\angle 4[/tex] are corresponding angles. ([tex]m\angle 2 = m\angle 4[/tex])
4) [tex]\angle 3[/tex] and [tex]\angle 4[/tex] are vertical opposite angles. ([tex]m \angle 3 = m \angle 4[/tex])
But, [tex]\angle 3[/tex] and [tex]\angle 5[/tex], since [tex]m \angle 3 + m\angle 6 + m\angle 5 = 180^{\circ}[/tex], where [tex]\angle 3[/tex] is an acute angle and [tex]\angle 6[/tex] is a right angle, and [tex]m \angle 4 + m \angle 5 = 90^{\circ}[/tex]. Then,
[tex]m\angle 5 = 90^{\circ} -m\angle 4[/tex].
[tex]m\angle 5 = 90^{\circ}-m\angle 3[/tex]
Hence, the right answer is E.
Read the description of 1844 Manchester England and write a short advertisement for a real estate company that might encourage people to move or work there.
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?
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.

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