I In a large survey, 1st graders were asked what their favorite color is. The probability that a first grader chose blue is 24%. If 8 students are randomly selected, what is the probability that exactly 2 students say blue

Answers

Answer 1

The probability that exactly 2 students say blue is their favourite colour is 0.3108.

What is Binomial DIstribution?

The binomial distribution with parameters n and p in probability theory and statistics is the discrete probability distribution of the number of successes in a series of n independent experiments, each asking a yes-or-no question and having its own Boolean-valued outcome: success (with probability p) or failure (with probability q = 1-p). A single trial or experiment that results in success or failure is known as a Bernoulli experiment, and a series of results is known as a Bernoulli process.The Binomial Distribution Formula is given as, [tex]P(X=k)= ^{n} C_{k}(p)^{k} (1-p)^{n-k}[/tex]

Here, the probability that the first grader chose blue is 24%.

[tex]\implies p=0.24[/tex]

The number of students randomly selected is 8.

[tex]\implies n=8[/tex]

So, the probability that exactly 2 students say blue is,

[tex]P(X=2)= ^{8} C_{2}(0.24)^{2} (1-0.24)^{8-2}\\\implies P(X=2)=28 \times 0.0576 \times (0.76)^{6} \\\implies P(X=2)=0.3108[/tex]

Thus, the probability that exactly 2 students say blue is 0.3108.

The length of the side of a cube having a density of 12. 6 g/ml and a mass of 7. 65 g is ________ cm

Answers

The  length of the side of a cube having a density of 12. 6 g/ml and a mass of 7. 65 g is 0.8467 cm.

What is Density?

The density of a substance reveals how dense it is in a certain space.The definition of density is the mass of a substance per unit volume.The formula for density is given as, [tex]D=\frac{m}{V}[/tex], where D is the density, m is the mass, and V is the volume.

In the question, it is given that the density is 12. 6 g/ml and mass is 7. 65 g.

[tex]\implies D=12.6[/tex] g/ml and [tex]m=7.65g[/tex]

So, the volume can be found by the formula,

[tex]V=\frac{m}{D}\\\implies V=\frac{7.65}{12.6}[/tex]

[tex]\implies V=0.6071[/tex] ml

We also know that the volume of the cube can be given as, [tex]V=(a)^{3}[/tex], where a is the length of the side of the cube.

So, [tex]a=\sqrt[3]{0.6071}[/tex]

[tex]\implies a=0.8467[/tex] cm

Thus, the length of the side of the cube is 0.8467 cm.

How to find the density of an object?

We are given;

Mass of first wood = 30 grams

Volume of first wood = 40 cubic centimeters(cm³).

The formula for the density of an object is;

Density = mass/volume

Thus

Density = 30/40

Density = 0.75 g/cm³

Now, the second piece of wood has the same density (g/cm³) and a volume of 240 cm³.

Thus;

Mass of second wood/240 = 0.75

Mass of second wood = 240 * 0.75

How does Wiesel feel about the power of memory? Highlight and label any rhetorical devices Wiesel uses to stress his point.

Passage: “Home, Despair, and Memory” By Elie Wiesel

Answers

Elie Wiesel is a Holocaust survivor, human rights advocate and writer, he wrote several books, one of the most famous one is Night, where he talks about his experience during the Holocaust and the impact it had on him and the power of memory in it.

In Night, Wiesel express his belief that the power of memory is essential to preserving the past and passing on the lessons of history. He uses various rhetorical devices to stress his point, including imagery, metaphor, and repetition.

For example, Wiesel repeatedly emphasizes the importance of bearing witness to the Holocaust, saying that "To forget would be not only dangerous but offensive; to forget the dead would be akin to killing them a second time" He uses imagery to describe the horrors he witnessed, such as describing the smell of burning flesh and ashes, this serve as a reminder of what happen.

He also uses metaphor to describe the impact of the Holocaust on his life, comparing it to a "golden chain" that links him to the past, and to the victims of the Holocaust.

identify various limiting factors (abiotic and biotic) in an ecosystem

Answers

Answer:

Explanation:

In ecology, biotic and abiotic factors make up an ecosystem. Biotic factors are the living parts of the ecosystem, such as plants, animals, and bacteria. Abiotic factors are the nonliving parts of the environment, such as air, minerals, temperature, and sunlight. Organisms require both biotic and abiotic factors to survive. Also, a deficit or abundance of either component can limit other factors and influence an organism's survival. The nitrogen, phosphorus, water, and carbon cycles have both biotic and abiotic components.

Answer:

Biotic factors are living things within an ecosystem; such as plants, animals, and bacteria, while abiotic are non-living components; such as water, soil and atmosphere. The way these components interact is critical in an ecosystem. Thus, organisms tend to compete for their limited availability in the ecosystem. Different limiting factors affect the ecosystem. They are (1) keystone species, (2) predators, (3) energy, (4) available space, and (5) food supply. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource.

Answers

The point estimate and the margin of error for this interval are 0.0265 and 0.1035 respectively.

What is Confidence Interval?

A confidence interval shows the likelihood that a parameter will be between two values that are close to its mean.The level of certainty or uncertainty in a sampling process is measured by confidence intervals.Additionally, they are employed in regression analysis and hypothesis testing.To determine statistical significance, statisticians frequently combine confidence intervals with p-values.They are often built using confidence intervals of 95% or 99%.

Here, the confidence interval for a difference in proportions is −0.077 to 0.13

We know that, the Lower Bound = Point Estimate - Margin of Error

Also, here, the Lower Bound = -0.077

And, Upper Bound = Point Estimate + Margin of Error

Here, the Upper Bound = 0.13

The Point Estimate can be determined as,

Point Estimate = (Upper Bound + Lower Bound) / 2

[tex]\implies[/tex] Point Estimate [tex]=\frac{0.13+(-0.077)}{2}[/tex]

[tex]\implies[/tex] Point Estimate [tex]=0.0265[/tex]

Now, Margin of Error = (Upper Bound - Lower Bound) / 2

[tex]\implies[/tex] Margin of Error [tex]=\frac{0.13-(-0.077)}{2}[/tex]

How many degrees was the figure rotated about the origin?


°

Answers

It means that the coordinates of the point were translated using the formula (x, y) since the point rotated at an angle of 180°. (-x, -y). As a result, the necessary rule that characterises the rotation about the origin is as follows: (-x, -y). Example of a 180 degree rotation when rotating a figure about its origin.

What is rotation ?

The circular movement of an object about a primary axis is referred to as rotation or spin. A revolving object in two dimensions only has one conceivable central axis and can revolve either clockwise or anticlockwise. There are countless conceivable central axes and rotating orientations for a three-dimensional object.

Here are the guidelines for rotation: rotation in the direction of 90°: (x,y) becomes (y,-x) rotation of (x,y) at 90 degrees anticlockwise results in (-y,x) Rotating (x, y) 180 degrees both clockwise and anticlockwise results in (-x,-y)

Thus, the necessary rule that characterises the rotation about the origin is as follows: (-x, -y).

An object moves 15. 0 m north and then 11. 0 m south. Find both the distance it has traveled and the magnitude of its displacement

Answers

Answer: The object ends up 4.0m north from the starting point, and the magnitude of the displacement is 4.0 m (northwards). ✅

Explanation:

The distance an object travels is the total distance it has moved in all directions. This can be found by adding up the distance it has moved in each direction.

In this case, the object moved 15.0 m north and then 11.0 m south. To find the total distance traveled, we add 15.0 m + 11.0 m = 26.0 m. So the distance traveled is 26.0 meters.

The magnitude of the displacement of an object is the distance and direction between the initial and final position. In this case, the object moved 15.0 m north and then 11.0 m south. So, the object ends up 4.0m north from the starting point, and the magnitude of the displacement is 4.0 m (northwards).
