Step-by-step explanation:

The point (-1,-1) is a part  of the line "y = -3x -4", because it satisfies the equation of line.

In order to determine if the point (-1,-1) is part of the line y = -3x - 4, we substitute the values of "x" and "y" into the equation and check if the equation holds true.

The point is (-1,-1), We Substitute x = -1 and y = -1 into the equation,

We get,

-1 = -3 × (-1) - 4,

On Simplifying,

We get,

-1 = 3 - 4

-1 = -1

Since both sides of the equation are equal, we can conclude that the point (-1,-1) is part of the line y = -3x - 4.

The mean of T is -10 and the standard deviation of T is √425 when X1 and X2 are independent.

To find the mean of T, we can use the properties of expected values. Since T = 11X1 - 2X2, the mean of T can be calculated as follows: E(T) = E(11X1) - E(2X2) = 11E(X1) - 2E(X2) = 11(10) - 2(20) = -10. To find the standard deviation of T, we need to consider the variances and covariance of X1 and X2. Since X1 and X2 are independent, the covariance between them is zero. Therefore, Var(T) = Var(11X1) + Var(-2X2) = 11^2Var(X1) + (-2)^2Var(X2) = 121(2^2) + 4(3^2) = 484 + 36 = 520. Thus, the standard deviation of T is √520, which simplifies to approximately √425. When X1 and X2 have a correlation of -0.76, the mean and standard deviation of T remain the same as in the case of independent variables. To calculate the probability P(T > 30) when X1 and X2 are independent, normally distributed variables, we need to convert T into a standard normal distribution. We can do this by subtracting the mean of T from 30 and dividing by the standard deviation of T. This gives us (30 - (-10))/√425, which simplifies to approximately 6.16.  We can then look up the corresponding probability from the standard normal distribution table or use statistical software to find P(T > 30). The probability will be the area under the standard normal curve to the right of 6.16.

The decimal expression for 4/33 is 0.121

The method for converting a fraction into a decimal expression can be done by dividing 4 by 33

First step would be dividing the 4 into 33 parts

As we know that 4 cannot be divided into 33 parts , hence we have to take an extra zero while dividing them, and while putting an extra zero in front of 4 we have to put a decimal sign.

4/33 = 4÷33

4÷33 = 0.121

now we have to put an extra zero in front of 4 in order to make it divisible by 33

Hence after calculation, we will get the answer nearest to 3 decimal places as 0.121

Option D is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

0.8133 is the probability  that a randomly chosen test taker will score between 560 and 640.

Probability is the possibility that something will happen, to put it simply. We can talk about the chance or likelihood of various outcomes when we don't know how an event will turn out. Events that follow a probability distribution are the subject of statistics.

Probability is a branch of mathematics that deals with numerical representations of how likely it is for an event to occur or for a proposition to be true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates that the event is impossible and 1 indicates certainty.

P(540< x 640)

=  P ( \(\frac{560 - 560}{90}\) < \(\frac{x - mu}{sigma}\) < \(\frac{640-560}{90}\) )

By resolving this, we will obtain a probability ranging from zero to triple zero. Therefore, the likelihood will be zero. Less than zero 89 minutes our chance of being zero is zero.

Answer:

Upper Quartile is 16 according to the diagram.

a)  The critical point is (-1/2, 7/16).

b)  The discriminant is negative, the critical points (0, -1) and (1, 1) do not have extrema.

c)   all the critical points (nπ, 0) are saddle points.

a) To find the critical points, we need to find the points where the partial derivatives of f(x, y) with respect to x and y are equal to zero.

Partial derivative with respect to x:

∂f/∂x = 3x^2 + 1 - 4y

Partial derivative with respect to y:

∂f/∂y = -4x - 2

Setting these partial derivatives equal to zero and solving the resulting system of equations, we can find the critical points:

3x^2 + 1 - 4y = 0 ...(1)

-4x - 2 = 0 ...(2)

From equation (2), we have -4x - 2 = 0, which gives x = -1/2. Substituting this value of x into equation (1), we get:

3(-1/2)^2 + 1 - 4y = 0

3/4 + 1 - 4y = 0

7/4 - 4y = 0

-4y = -7/4

y = 7/16

Therefore, the critical point is (-1/2, 7/16).

To determine the nature of this critical point, we can calculate the second partial derivatives:

∂²f/∂x² = 6x

∂²f/∂y² = 0

∂²f/∂x∂y = -4

The discriminant for this point is D = (∂²f/∂x²)(∂²f/∂y²) - (∂²f/∂x∂y)² = (6x)(0) - (-4)² = 16.

Since the discriminant is positive and ∂²f/∂x² = 6x, the critical point (-1/2, 7/16) is a relative minimum.

(b) To find the critical points for f(x, y) = x(y + 1) - x²y, we need to find where the partial derivatives with respect to x and y are equal to zero.

Partial derivative with respect to x:

∂f/∂x = y + 1 - 2xy

Partial derivative with respect to y:

∂f/∂y = x - x²

Setting these partial derivatives equal to zero, we get:

y + 1 - 2xy = 0 ...(1)

x - x² = 0 ...(2)

From equation (2), we have x - x² = 0, which gives x(x - 1) = 0. This implies that x = 0 or x = 1.

Case 1: x = 0

Substituting x = 0 into equation (1), we have:

y + 1 = 0

y = -1

Therefore, one critical point is (0, -1).

Case 2: x = 1

Substituting x = 1 into equation (1), we have:

y + 1 - 2y = 0

-y + 1 = 0

y = 1

Therefore, another critical point is (1, 1).

To determine the nature of these critical points, we calculate the second partial derivatives:

∂²f/∂x² = -2

∂²f/∂y² = 0

∂²f/∂x∂y = -2

The discriminant for both critical points is D = (∂²f/∂x²)(∂²f/∂y²) - (∂²f/∂x∂y)² = (-2)(0) - (-2)² = -4.

Since the discriminant is negative, the critical points (0, -1) and (1, 1) do not have extrema.

(c) To find the critical points for f(x, y) = cos(x) cosh(y), we need to find where the partial derivatives with respect to x and y are equal to zero.

Partial derivative with respect to x:

∂f/∂x = -sin(x) cosh(y)

Partial derivative with respect to y:

∂f/∂y = cos(x) sinh(y)

Setting these partial derivatives equal to zero, we get:

-sin(x) cosh(y) = 0 ...(1)

cos(x) sinh(y) = 0 ...(2)

Equation (1) implies that sin(x) = 0, which occurs when x = nπ for n being an integer.

Equation (2) implies that sinh(y) = 0, which occurs when y = 0.

Therefore, the critical points are of the form (nπ, 0), where n is an integer.

To determine the nature of these critical points, we can calculate the second partial derivatives:

∂²f/∂x² = -cos(x) cosh(y)

∂²f/∂y² = cos(x) cosh(y)

∂²f/∂x∂y = -sin(x) sinh(y)

The discriminant for these critical points is D = (∂²f/∂x²)(∂²f/∂y²) - (∂²f/∂x∂y)² = (-cos(x) cosh(y))(cos(x) cosh(y)) - (-sin(x) sinh(y))² = cos²(x) cosh²(y) - sin²(x) sinh²(y).

Since cos²(x) and cosh²(y) are always positive, and sin²(x) and sinh²(y) are always non-negative, the discriminant D will always be non-negative.

Therefore, all the critical points (nπ, 0) are saddle points.

The overall shape of a distribution is described by its symmetry or skewness. If the distribution is symmetrical, it means that the data are evenly distributed around the mean, and the graph will be bell-shaped.

If the distribution is skewed to the left, it means that there are more extreme values on the left side of the graph, and the tail will be longer on the left side. If the distribution is skewed to the right, it means that there are more extreme values on the right side of the graph, and the tail will be longer on the right side. If the distribution is uniform, it means that all values are equally likely, and the graph will be flat.
