What numbers are in the range of S(n)?

The ratio of the given expression is equal to 1:16.

Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. The foundation for understanding the numerous concepts in mathematics and science is provided by the two key notions of ratio and proportion.

We apply the concepts of ratio and proportion every day, for example, while dealing with money in business or when preparing any meal, etc. Sometimes, pupils struggle to understand the relationship between ratio and proportion.

We have x=1 and y=2, and we have to find the ratio of x4:y4,

The correct way to report the length of the rectangle in centimeters would be (b)"15.6 cm".

A rectangle in Euclidean plane geometry is a quadrilateral with four right angles. It can alternatively be described as a parallelogram with a right angle or an equiangular quadrilateral, where equiangular denotes that all of its angles are equal (360°/4 = 90°).

The general practice is to report measurements to the appropriate number of significant digits. In this case, "15.6 cm" accurately reflects the measurement to the nearest tenth of a centimeter and uses the proper unit symbol (cm). "15.600 cm" and "15.60 cm" include more significant digits than are necessary and "16 cM" uses an incorrect unit symbol.

Given matrices A and Q, the matrix R can be calculated as: R = Q^T * A.

The QR factorization is the factorization of a matrix A into an orthogonal matrix Q and an upper triangular matrix R. Given matrices A and Q, the matrix R can be calculated as:

R = Q^T * A

Where Q^T is the transpose of Q.

Note that this calculation assumes that Q is an orthogonal matrix, meaning that its transpose is equal to its inverse. If Q is not orthogonal, it will not have an inverse and the QR factorization cannot be calculated in this manner.

Therefore, Given matrices A and Q, the matrix R can be calculated as: R = Q^T * A.

If q² – 4pr > 0, the roots of the quadratic equation px² + qx + r = 0 will be: "negative, if p, q, and r are positive". Therefore, Suman answered correctly.

In Mathematics, a quadratic function can be defined as a mathematical expression which defines and represent the relationship that exists between two (2) or more variable on a graph, with a maximum exponent of two.

Generally speaking, the standard form of a quadratic function is given by ax² + bx + c = 0.

Assuming the roots of the quadratic function are a and b. Therefore, the sum of the roots of the quadratic function would be equal to -q/p;

a + b = -q/p

ab = r/p

This ultimately implies that, the nature of the roots would depend on the value of p, q and r, which make Zain's answer to be wrong.

Additionally, if p, q, and r are positive, a + b would be negative, and one or both roots must be negative, which make Vipul's to be wrong.

The value of the correlation coefficient would not change.

The following would be the correlation change if the stopping distances were recorded in meters, rather than feet.

Hence, option (A) is the correct choice.

Correlation is a statistical number derived based on historical data (profitability), and, contrary to popular belief, it is not constant and can change over time.

Correlation is a statistical term that reflects how much two or more variables vary in relation to one another.

The correlation coefficient is evaluated on a scale ranging from + 1 to - 1. The degree of correlation between two variables is denoted by + 1 or -1. When one variable rises as the other rises, the correlation is positive; when one falls as the other rises, the correlation is negative.

The slope-intercept equation of the line that includes the points (1, 1) and (2, 8) is y = 7x - 6.

In Mathematics, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

Next, we would determine the linear equation representing the line which passes through the points (1, 1) and (2, 8) by using the point-slope form as follows:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 1 = (8 - 1)/(2 - 1)(x - 1)

Answer:

15 prints

Step-by-step explanation:

Let's call the number of small prints sold as "x".

The number of medium prints sold is then (52 - x) prints.

We know that the total revenue from all the prints sold is $2,975, so we can set up the following equation:

$2975 = (x * $50) + ((52 - x) * $75)

Expanding and solving for x:

$2975 = $50x + $3900 - $75x

$2975 = $3900 - $25x

$-925 = -$25x

x = 37

Step-by-step explanation:

Normally distributed residuals is not an assumption of the general linear model and hence option b is correct

Linear regression models relate to some assumptions about the distribution of error terms. If they are violated violently, the model is not suitable for drawing conclusions. Therefore, it is important to consider the suitability of the model for information before further analysis can be performed based on this model.

The fit of the model is related to the remaining behavior complying with the basic assumptions for error values in the model. When a regression model is constructed from a series of data, it should be shown that the model responds to the standard statistical assumptions of the linear model because of conducting inference. Residual analysis is an effective tool to investigate hypotheses. This method is used to test the following statistical assumptions for a simple linear regression model:

-Regression function is linear in parameters,

-Error conditions have constant variance,

-Error conditions are normally distributed,

-Error conditions are independent.

Normally distributed residuals is not an assumption of the general linear model and hence option b is correct

The rate of change of f'(x) at (1, 13) is 25.

We have,

To find the rate of change of the derivative f'(x) at point (1, 13), we first need to find the derivative of the function f(x).

Given: f(x) = 14x² - x³

To find f'(x), we differentiate f(x) with respect to x:

f'(x) = d/dx (14x² - x³)

= 28x - 3x²

Now, to find the rate of change of f'(x) at x = 1,

we substitute x = 1 into the derivative expression f'(x):

f'(1) = 28(1) - 3(1)²

The normal probability distribution is a continuous probability distribution that is symmetrical and bell-shaped. It is described by its mean and standard deviation, and its graph can be used to represent the distribution of a continuous random variable. The total area under the curve of the normal distribution is equal to 1, which represents the probability of observing any value within the range of the distribution.

The mean, median, and mode of a normal distribution are equal and located at the center of the distribution. This is why the normal distribution is often referred to as the "bell-shaped" distribution. The shape of the curve is a smooth, symmetrical shape that slopes gently and then becomes more steep as it approaches the tails of the distribution.

Finally, it's true that a random variable that follows a normal distribution assumes a value within plus or minus three standard deviations of its mean 99.72% of the time. This is a property of the normal distribution known as the empirical rule or the 68-95-99.7 rule.

In summary, the statement "the graph of the curve is the shape of a rectangle" is not a characteristic of the normal probability distribution, while the other statements are.
