In a orchestra , 10% the musicians play brass instruments. 15% play woodwin and, %5 play percussion .The other 28 musicians olay stringed insturments.

how many musicians are in the orchestra altogther? ​

Answers

Ok so basically 100% is the total amount of like percentage. It stand for 1 . But since you have 3 different percentages, you would use 100% instead.
Firstly, add up the percentages:
10%+15%+28% ( don’t worry about the percentage sign)
= 53% that would be the percentage of the musicians+Woodwind+percussion

28 other play stringed instruments, what you do is u want to change 53%to a normal number , so 53% is out of 100 , so 53/100x100= 53 , and 53+28= 81.

—There are 81 musicians altogether .

guys please help me it's Find the area of the polygon

Answers

For the first figure, draw a vertical line from the upper right corner to the base. Then you can see that the figure is a combination of two shapes: A rectangle that is 8 high and 6 wide, and a right triangle that has altitude of 8 and base of 4.

Area of rectangle = 8*6 = 48
Area of triangle = (1/2)*8*4 = 16
Total area = 48+16 = 64 square units
:::::
The second figure is a parallelogram with equal sides. Note that if you cut off the triangular area and attach it to the top of the figure, you get a rectangle, so the area is 15 times 16 = 24 units.

The diameter of a circle is 55 inches.

​

​Find the length of its radius.

​

Answer:​
inches
​

Answers

The radius would be 8.75

Answer:

27.5 inches

Step-by-step explanation:

The circle's "radius" refers to the distance from the center towards the circumference. Once the diameter of a circle is given, it is easy to get the radius. In order to get the length of the circle's radius, all you have to do is to divide the diameter (55 inches) into two.

55 inches ÷ 2 = 27.5 inches

Therefore, the circle's distance from the center towards the circumference is 27.5 inches. This is the radius.

Animal researchers studying cows and horses conducted a two-sample t-test for a difference in means to investigate whether grazing cows eat more grass, on average, than grazing horses. All conditions for inference were met, and the test produced a test statistic of t=1.064 and a P-values of 0.0487 Which of the following is a correct interpretation of the P-value?
A. The probability that cows eat more grass than horses, on average, is 0.0487.
B. The probability that cows eat the same amount of grass as horses, on average, is 0.0487
C. Assuming that the mean amount of grass eaten by cows is greater than the mean amount of grass eaten by horses, the probability of observing a test statistic of at most 1.664 is 0.0487.
D. Assuming that the mean amount of grass eaten by cows is equal to the mean amount of grass eaten by horses, the probability of observing a test statistic of at most 1.664 is 0.0487.
E. Assuming that the mean amount of grass eaten by cows is equal to the mean amount of grass eaten by horses, the probability of observing a test statistic of at least 1.664 is 0.0487.

Answers

Answer:

E. Assuming that the mean amount of grass eaten by cows is equal to the mean amount of grass eaten by horses, the probability of observing a test statistic of at least 1.664 is 0.0487

Step-by-step explanation:

Given that :

Test statistic, t = 1.064

P-value = 0.0487

Hypothesis : To test if grazing cows eat more grass than grazing horses

The null hypothesis will be :

H0 : μ1=μ2 (that is there is no difference on the mean number of grass eaten by cows and horses).

Alternative hypothesis ; H1 : μ1 > μ2

The null is assumed true unless tested otherwise, the P-value is used as a probability metric for the rejection or acceptance of the null.

Therefore, if the null is True in this scenario, then, the probability of observing a test statistic of at least 1.664 is 0.0487

If the null is true in this scenario, then the probability of observing a test statistic of at least 1.664 is 0.0487.

What are null hypotheses and alternative hypotheses?

In null hypotheses, there is no relationship between the two phenomenons under the assumption or it is not associated with the group. And in alternative hypotheses, there is a relationship between the two chosen unknowns.

Test statistics, t = 1.064

P-value = 0.0487

The null hypothesis will be

H₀: μ₁ = μ₂ (There is no difference in the mean number of grass eaten by cows and horses)

An alternative hypothesis will be

Hₐ: μ₁ > μ₂

The null is assumed true unless tested otherwise, the P-value is used as a probability metric for the rejection or acceptance of the null.

Therefore, if the null is true in this scenario, then the probability of observing a test statistic of at least 1.664 is 0.0487.

¿De qué manera influye la ética en el hombre a partir de su función crítica? Explique.

Answers

Answer:

La ética es una rama de la filosofía que se ocupa de la reflexión crítica sobre las acciones de los hombres. En un sentido general, la ética busca establecer los criterios para juzgar si una acción puede calificarse de correcta o incorrecta, y para evaluar los motivos y consecuencias de dicha acción. Las cuestiones éticas también juegan un papel importante en la política, los negocios y la medicina, y en campos de la ciencia y el estudio como la historia, la biología y la sociología, la ética de la profesión es ocasionalmente un tema de discusión.

Así, la ética implica una evaluación de las acciones de las personas, calificándolas como correctas o incorrectas a los ojos de la sociedad. De esta manera, influye en la forma en que las personas realizan o dejan de realizar una determinada acción, ya que estas consideran sus consecuencias positivas o negativas al momento de realizarla.

HELPPPPPPPPP PLZZZZZ Fact Pattern:Peter Protester is a fairly well-known rabble-rouser. His demonstrations have made news across the southwest, and he's been on TV several times. Now, he has had it with the current state of politics. He gathers his group of followers, and they head to downtown Phoenix to make their grievances known. Peter's followers are generally law-abiding, but there are a few in there who have been arrested after turning peaceful protest into vandalism.After about two hours of chanting and marching, Peter yells, "Alright, we've done the peaceful thing long enough. Now let's take some real action! Let's start breaking some windows now!"Phoenix Police immediately arrest him.Meantime, Rachel Reporter is in the KPHO-TV newsroom and gets a call from a police source. The source tells Rachel to take a look at the police report from Peter's arrest. Rachel heads down to the Phoenix Police Records Department and gets a copy of the police report. In it, the arresting officer writes, "This is the same Peter Protester who was convicted of domestic terrorism in 2010."Rachel believes she has a real scoop on her hands and calls for a live truck to meet her at the scene of the protest. Rachel's live report includes the news of today's arrest. She also quotes the police report, saying Peter was convicted of domestic terrorism in 2010." Rachel did not check with police or try to get ahold of Peter in jail or speak to his lawyer to verify the conviction.As it turns out, the police report was inaccurate. Peter was never convicted of domestic terrorism.What charge would prosecutors likely file against Peter and will the case succeed? why?If Peter sues Rachel, what lawsuit would he likely file and would he succeed? why? Is actual malice required here and is it present? why? Does the fair report privilege apply here to protect Rachel from liability? why?
