Biologists estimate that a randomly selected baby elk has a 46% chance of surviving to
adulthood. Assume this estimate is correct. Suppose researchers choose 8 baby elk at
random to monitor. Let x = the number that survive to adulthood.
Determine whether the scenario above describes a binomial setting. Justify your answer.
Use the binomial probability formula to find P (X = 4). Interpret this value.

Answers

Answer 1

Answer:

p (X= 4) = 0.266

Explanation:

Probability of randomly selected baby elk to survive adulthood = 46%

As per binomial setting

p (X= k)  = [tex]\frac{n!}{k! * (n-k)!} p^k(1-p)^{n-k}[/tex]

Substituting the given values, we get -

p (X= 4)  = [tex]\frac{8!}{4! * (8-4)!} 0.46^4(1-0.46)^{8-4}[/tex]

p (X= 4)   =   [tex]\frac{8*7*6*5 *0.44775 * 0.0850306}{4*3*2*1}[/tex]

p (X= 4) = 0.266

What does the sales force estimation method rely on for forecasting future sales?

Answers

Answer:

Bottom-up method

Explanation:

The bottom-up method is a good way to promote sales forecast, especially if it is desirable to make a monthly forecast. Through this method, the trader can predict how many units he will sell in the month. This is done by calculating the average price of each unit, which will be multiplied by the number of units of the product, thus giving an estimated number of monthly sales.

Which of the following goods belong in a competitive market, and which belong in an imperfect market?

electricity providers
gasoline bought at gas stations at a busy interstate exit
a fresh produce stand at a farmers’ market
a furniture store in an isolated small town
all the fast-food restaurants in your town
university education

Answers

Ik the brainliest is cap but here are the answers

The goods have been categorized into the competitive and imperfect market as follows:

Competitive Market

- gasoline bought at gas stations at a busy interstate exit  

- a fresh produce stand at a farmers' market

Imperfect Market

- electricity providers

- a furniture store in an isolated small town

- all the fast-food restaurants in your town

- university education

A competitive market is characterized as a market where a number of producers come together in a competition to serve the consumer's needs and demands.In such a market, homogeneous or identical products are available, and therefore, the prices are determined by the market forces.Since 'gasoline...stations' exemplify the presence of similar products and 'a fresh produce...market' demonstrate plenty of producers, they would be classified under 'competitive market.'

An imperfect market is described as a market having a number of sellers yet they sell distinct goods and the consumers do not possess proper knowledge about them. Since the electricity providers are controlled monopolies, 'a furniture store...isolated' is not known to people, the university education and fast-food outlets offer distinct goods, they all would be characterized under imperfect market.

why might Washington have chosen to look the other way on segregation and to appease white Southerners?

Answers

Answer: So that African Americans could develop in peace.

Explanation:

Booker T. Washington was one of the most famous and powerful African Americans of his time. He founded the Tuskegee Institute which was a higher institution to educate African Americans and tried to educate and sponsor as many black-owned businesses as he could.

In a very iconic speech called the ''Atlanta Compromise'', he told a mainly white audience that African Americans would not oppose segregation or equality if they were given education and due process in legal issues.

It would seem that he believed that so long as Black people advocated for equality and integration, the whites would always be against their development and would treat them unfairly. If they accepted their situation however, he reasoned that the whites may be more inclined to allow black people access to education and fair trials.
