Step-by-step explanation:

The polynomial representing the area of the is 49n² - 25

The formula for area of a square is expressed as;

Area = a²

Where a is the side length

From the image shown, we can see that the side length takes the value (7n - 5)

Substitute the value into the formula

Area = a²

Area = (7n - 5)²

Area = (7n - 5) ( 7n + 5); this is so because of the difference of two squares

Expand the bracket

Area = 49n² + 35n - 35n - 25

collect like terms

Area = 49n² - 25

Thus, the polynomial representing the area of the cube is 49n² - 25

The 95% confidence interval for the proportion of adults who think critical thinking should be taught in schools, is based on an online poll of 810 respondents, with a margin of error of 4.1%.

The margin of error represents the maximum amount of deviation from the sample statistic that we can tolerate while still maintaining a certain level of confidence in our estimate. In this case, the margin of error is 4.1%, which means that we allow for a potential error of plus or minus 4.1% around the observed proportion of 53%.

To calculate the confidence interval, we subtract the margin of error from the observed proportion to obtain the lower bound, and add the margin of error to the observed proportion to obtain the upper bound. Therefore, the 95% confidence interval is approximately 53% - 4.1% to 53% + 4.1%, which results in a range of approximately 48.9% to 57.1%. In a meaningful sentence, we can say that based on the poll data, we are 95% confident that the proportion of adults who believe that critical thinking should be taught in schools lies between 48.9% and 57.1%.

As for whether we would agree with an article claiming that a 'majority' of people think critical thinking should be taught in school, it depends on the definition of 'majority.' If 'majority' is defined as more than 50%, then the claim would be supported by the confidence interval, as it includes the threshold for a majority. However, if 'majority' is defined as a significantly larger proportion, such as two-thirds or more, then the claim would not be supported by the confidence interval, as the upper bound of the interval is below that threshold.

Answer:

A

Step-by-step explanation:

Answer: the answer is B: (3,9)

Step-by-step explanation:

Answer:

James deliver newspaper in 1 hour=130

Marks deliver newspaper in 1 hour= 210/3=70

so lf they work together to deliver 1000 newspaper they take 130+70=200. 1000/200=5.

so they take 5 hours to deliver 1000 newspaper.

It would take 5 hours for James and Mark to deliver 1000 newspapers.

Equation is an expression used to show the relationship between two or more variables and numbers.

James delivers 130 papers in one hour (130/1) and Mark delivers 210 papers in three hours(70 papers in 1 hours), hence:

For 1000 newspapers:

(130 + 70)t = 1000

t = 5 hours

It would take 5 hours for James and Mark to deliver 1000 newspapers.

Step-by-step explanation:

2 ≤ 2x+4 <10

Subtract 4 from all sides.

2-4 ≤ 2x+4-4 <10-4

-2 ≤ 2x <6

Divide 2 from all sides.

-2/2 ≤ 2x/2 <6/2

The point on the ellipse that is farthest from the origin will be the point that is closest to one of the foci.

To find the points on the ellipse that are nearest to and farthest from the origin, we need to consider the equation of the paraboloid and the equation of the ellipse.

The equation of a paraboloid is given by:

\(z = ax^2 + by^2 + c\)

where a, b, and c are constants.

The equation of an ellipse is given by:

\((\frac{x}{a})^2 + (\frac{y}{b})^2 = 1\)

where a and b are the semi-major and semi-minor axes of the ellipse, respectively.

If the plane intersects the paraboloid in an ellipse, then the equations of the paraboloid and the ellipse must be equal at the points of intersection. Therefore, we can set the equation of the paraboloid equal to the equation of the ellipse and solve for the x and y values.

\(z = ax^2 + by^2 + c\)

\((\frac{x}{a})^2 + (\frac{y}{b})^2 = 1\)

Substituting the equation of the paraboloid into the equation of the ellipse, we get:

\((\frac{x}{a})^2 + (\frac{y}{b})^2+c = 1\)

We can then solve this equation for the values of x and y that correspond to the points on the ellipse that are nearest to and farthest from the origin.

The point farthest away from the origin occurs at the point on the ellipse that is farthest from the center, which is called the "foci" of the ellipse. The distance from the center of the ellipse to the foci is called the "eccentricity" of the ellipse. The eccentricity is denoted by the letter "e" and is calculated using the following formula:

\(e = \frac{\sqrt{(a^2 - b^2)}}{a}\)

where a and b are the semi-major and semi-minor axes of the ellipse, respectively.

Therefore, to find the point on the ellipse that is farthest from the origin, we need to calculate the eccentricity of the ellipse and then use this value to determine the location of the foci. The point on the ellipse that is farthest from the origin will be the point that is closest to one of the foci.

Step-by-step explanation:

The simulation will say that Jeffrey collected three different toys if the numbers in a group of three are either 0 or 1, a number more than 1 and less than 6, and a number 6 or more.

The groups {3, 7, 1}, {5, 1, 7}, {9, 2, 0}, {3, 0, 6} and {4, 6, 0} all simulate collection of all three toys from three boxes of cereal. Of the 15 simulated sets of three boxes, that is a probability of 5/15, or 1/3.

_____

Additional comment

The simulated toy numbers can be grouped in different ways. For example, we could take a vertical column of numbers as representing the purchase of 3 boxes of cereal. Doing that, we find 3 different toys only for the simulated values {4, 0, 6}, the last digits in the 4th column. The probability from considering the simulation that way is 1/15.

From this group of 45 numbers, one could calculate P(car) = 10/45, P(bus) = 19/45, and P(airplane) = 16/45. These vary a little from the theoretical values. Overall, with these values, the probability of 3 different toys from 3 boxes is about 0.200, only slightly different from the theoretical probability of 0.192.

For a result to be considered significant, the chances of its occurring as a result of random error are often less than 5 percent.

A coincidental discrepancy between the observed and true values of anything is known as a random error (e.g., a researcher misreading a weighing scale records an incorrect measurement).

It's not always a mistake when there is random error; rather, it happens when measurements are made. Even when you measure the same item repeatedly, there will always be some variation in your results because to changes in the environment, the instrument, or your own perceptions.

Your measurements are equally likely to be greater or lower than the genuine values due to random error, which has unexpected effects.

The probability that you will be satisfied with 3 or more of the purchased products is 0.916

Given that,

The chance of being pleased with an internet purchase is 0.555. if you purchase 8 items online

Solution -

let  X denote the no of success of

Purchased product online

X ~ B(n,p)

n = 8

P= 0. 555

a = 1 - 0 .555 = 0.445

P ( X = x) = \(nc_{x} b^{x} a^{n-x}\)

P ( X = x)= \(8c_{x} (0.555^{x} )(0.445)^{8-x\)

P ( X>=3)= \(\lim_{3 \to 8} 8c_{x} (0.555^{x} )(0.445)^{8-x\)

P ( X>=3)) = 0.91614

Answer:

The constant of proportionality is 3/4

Step-by-step explanation:

Here, we want to write the constant of proportionality in the given graph .

To find the constant of proportionality, we need to find the slope of the line.

We can get the slope by using two of the points on the line.

Mathematically, slope of a line m is;

m = (y2-y1)/(x2-x1)

Let (x1,y1) = (120,90) and (x2,y2) = (400,300)

slope will be ( 300-90)/(400-120) = 210/280 = 3/4
