The type of sampling is stratified random sampling

Given that,

The population is first divided into subgroups based on one or more important variables. this sampling is nothing but stratified random sampling

What Is Stratified Random Sampling?

A crucial element of the sampling method known as stratified random sampling is the division of a population into smaller subgroups known as strata. Strata are established in stratified random sampling, also known as stratification, based on the shared characteristics or attributes of the participants, such as wealth or level of education. Examining life expectancy and population demographics is just one of the many benefits and uses of stratified random sampling. Other names for stratified random sampling are proportional or quota random sampling..

Hence, this sampling is stratified random sampling

Step-by-step explanation:

The slope of the parametric curve x=-\(2t^3\)+7, y=3t² at the point corresponding to t is -1 divided by t.

To find the slope of the parametric curve x=-\(2t^3\)+7, y=3t², we need to take the derivative of y with respect to x.

To do this, we can use the chain rule:

(dy/dx) = (dy/dt) / (dx/dt)

where (dx/dt) is the derivative of x with respect to t, and (dy/dt) is the derivative of y with respect to t.

Taking the derivatives, we get:

dx/dt = -6t²

dy/dt = 6t

Substituting these values, we get:

(dy/dx) = (dy/dt) / (dx/dt) = (6t) / (-6t²) = -1/t

So, the slope of the curve at the point corresponding to t is -1/t.

The force F = r^2k(r^) is not conservative because its curl is nonzero. The force is central because it depends only on r and acts along the radial direction. Since it is not conservative, there is no potential energy function V(r) associated with this force

To determine whether the force F = r^2k(r^) is conservative and central, let's analyze its properties.

A force is conservative if it satisfies the condition ∇ × F = 0, where ∇ is the gradient operator. In Cartesian coordinates, the force can be written as F = Fx i + Fy j + Fz k, where Fx, Fy, and Fz are the components of the force in the x, y, and z directions, respectively. The curl of F is given by:

∇ × F = (∂Fz/∂y - ∂Fy/∂z)i + (∂Fx/∂z - ∂Fz/∂x)j + (∂Fy/∂x - ∂Fx/∂y)k.

Calculating the components of F = r^2k(r^):

Fx = 0, since there is no force component in the x-direction.

Fy = 0, since there is no force component in the y-direction.

Fz = r^2kr^.

Taking the partial derivatives, we have:

∂Fz/∂x = ∂/∂x (r^2kr^) = 2rkr^2(∂r/∂x) = 2rkr^2(x/r) = 2xkr^3.

∂Fz/∂y = ∂/∂y (r^2kr^) = 2rkr^2(∂r/∂y) = 2rkr^2(y/r) = 2ykr^3.

Substituting these values into the curl equation, we get:

∇ × F = (2ykr^3 - 2xkr^3)k = 2k(r^3y - r^3x).

Since the curl of F is not zero, ∇ × F ≠ 0, we conclude that the force F = r^2k(r^) is not conservative.

Now let's determine if the force is central. A force is central if it depends only on the distance from the origin (r) and acts along the radial direction (r^).

For F = r^2k(r^), the force is indeed central because it depends solely on r (the magnitude of the position vector) and acts along the radial direction r^. Hence, it can be written as F = Fr(r^), where Fr is a function of r.

Since the force is not conservative, it does not possess a potential energy function. In conservative forces, the potential energy function V(r) can be defined, and the force can be expressed as the negative gradient of the potential energy, i.e., F = -∇V. However, since F is not conservative, there is no potential energy function associated with it.

To calculate Mr. Yadav's income tax, we need to know the tax rate that applies to his income level. In India, the tax rate for income between Rs. 5,00,001 to Rs. 10,00,000 is 20%. Assuming that Mr. Yadav's taxable income is Rs. 8,00,000, his income tax liability would be 20% of Rs. 3,00,000 (Rs. 8,00,000 minus Rs. 5,00,000), which is Rs. 60,000. Therefore, Mr. Yadav would have paid Rs. 60,000 in income tax last year.

To solve the system Rx = у, where R is an nxn upper triangular matrix with semi-band width s, we can use the back-substitution method, which involves solving for x in the equation R*x = y.

The back-substitution algorithm starts with the last row of the matrix R and solves for the last variable x_n, using the corresponding entry in y and the entries in the last row of R.

Then, it moves on to the second-to-last row of R and solves for the variable x_{n-1} using the entries in the second-to-last row of R, the known values of x_{n}, and the corresponding entry in y. The algorithm continues in this way, moving up the rows of R, until it solves for x_1 using the entries in the first row of R and the known values of x_2 through x_n.

Since R is an upper triangular matrix with semi-band width s, the non-zero entries are confined to the upper-right triangle of the matrix, up to s rows above the diagonal.

This means that in each row of the back-substitution algorithm, we only need to consider at most s+1 entries in R and the corresponding entries in y. Furthermore, since the matrix R is triangular, the entries below the diagonal are zero, which reduces the number of operations needed to solve for each variable.

Thus, in each row of the back-substitution algorithm, we need to perform at most s+1 multiplications and s additions to solve for a single variable. Since there are n variables to solve for, the total number of operations required by the back-substitution algorithm is approximately 2ns flops.

An analogous result holds for lower-triangular systems, where the entries are confined to the lower-left triangle of the matrix. In this case, we use forward-substitution instead of back-substitution to solve for the variables, starting from the first row of the matrix and moving down. The number of operations required is again approximately 2ns flops.

Using the equation and cross-multiplication method, we know that the perimeter of the triangle IJK is 180.4 units.

A triangle is a polygon with three edges and three vertices.

It belongs to the basic geometric shapes.

A triangle having vertices A, B, and C is known as triangle ABC.

Any three locations in Euclidean geometry that are not collinear result in a distinct triangle and a distinct plane.

The closed, two-dimensional shape known as a triangle has three sides, three angles, and three vertices.

A triangle is part of a polygon.

So, we know that:

We must ascertain the value of x in order to determine the triangle's perimeter, IJK.

Using the ratio of comparable triangles and the triangles above, we have:

HF/KI = FG/IJ

Where,

HF = 35, KI = 77, FG = 27 and IJ = x

By changing the values, we obtain:

35/77 = 27/x

Take the cross product of the aforementioned equation, and we have:

35x = 27*77

x = 27*77/35 = 27 * 11/5 = 59.4

The triangle's perimeter is thus equal to the sum of its sides:

△IJK = 44 + 77 + 59.4 = 180.4

Therefore, using the equation and cross-multiplication method, we know that the perimeter of the triangle IJK is 180.4 units.

The derivative of the operations with the functions are: g(x) + h(x) + j(x) = 6x + 2, h(x) + j(x) - g(x) = 6x + 1, j(x)⋅g(x) = 4x + 1, h(x)/g(x) = 3 and j(h(x)) = 36x³ + 6x.

To find the derivatives of the given operations with the functions f(x) = 5, g(x) = x, h(x) = 3x², and j(x) = 2x + 1, we will apply the rules of differentiation.

Gg(x) + h(x) + j(x):

The derivative of a sum of functions is equal to the sum of their derivatives. Therefore, we find:

d/dx[g(x) + h(x) + j(x)] = d/dx g(x) + d/dx h(x) + d/dx j(x)

d/dx[g(x) + h(x) + j(x)] = 0 + 6x + 2

d/dx[g(x) + h(x) + j(x)] = 6x + 2

So, the derivative of g(x) + h(x) + j(x) is 6x + 2.

h(x) + j(x) - g(x):

Similarly, the derivative of a difference of functions is equal to the difference of their derivatives. We have:

d/dx[h(x) + j(x) - g(x)] = d/dx h(x) + d/dx j(x) - d/dx g(x)

d/dx[h(x) + j(x) - g(x)] = 6x + 2 - 1

So, the derivative of h(x) + j(x) - g(x) is 6x + 1.

j(x) ⋅ g(x):

To differentiate the product of two functions, we use the product rule. Applying the rule, we get:

d/dx [j(x) ⋅ g(x)] = g(x) ⋅ d/dx j(x) + j(x) ⋅ d/dx g(x)

d/dx [j(x) ⋅ g(x)] = x ⋅ 2 + (2x + 1) ⋅ 1

Simplifying, we have:

d/dx [j(x) ⋅ g(x)] = 2x + 2x + 1

d/dx [j(x) ⋅ g(x)] = 4x + 1

Therefore, the derivative of j(x) ⋅ g(x) is 4x + 1.

h(x) / g(x):

To differentiate the division of two functions, we use the quotient rule. The rule states:

d/dx [h(x) / g(x)] = (g(x) ⋅ d/dx h(x) - h(x) ⋅ d/dx g(x))/g(x)²

Applying the rule, we find:

d/dx [h(x) / g(x)] = (x ⋅ 6x - 3x² ⋅ 1)/x²

Simplifying, we get:

d/dx [h(x) / g(x)] = (6x² - 3x²) / x²

d/dx [h(x) / g(x)] = 3

Therefore, the derivative of h(x) / g(x) is 3.

j(h(x)):

To find the derivative of a composite function, we use the chain rule. The chain rule states:

d/dx [f(g(x))] = f'(g(x)) ⋅ g'(x)

Applying the chain rule, we have:

d/dx [j(h(x))] = d/dx [j(u)] (where u = h(x))

d/dx [j(h(x))] = d/du [j(u)] ⋅ du/dx

d/dx [j(h(x))] = (2u + 1) ⋅ (d/dx [h(x)])

d/dx [j(h(x))] = (2(3x²) + 1) ⋅ (6x)

Simplifying, we get:

d/dx [j(h(x))] = (6x² + 1) ⋅ (6x)

d/dx [j(h(x))] = 36x³ + 6x

Therefore, the derivative of j(h(x)) is 36x³ + 6x.

The extent to which an instrument is consistent within itself is called reliability.

Reliability refers to the consistency or stability of the measurements obtained using a specific instrument or test. In other words, it is the degree to which a tool or instrument measures the same way each time it is used under the same conditions. If an instrument is reliable, it produces consistent results across repeated trials or measurements.

Reliability is an important aspect of measurement because it determines the accuracy of the results obtained using the instrument. An unreliable instrument can produce inconsistent or inaccurate results, which can lead to erroneous conclusions or decisions.

Therefore, it is crucial to establish the reliability of an instrument before using it to make important decisions or draw conclusions based on the measurements obtained. There are several methods for measuring reliability, including test-retest reliability, inter-rater reliability, and internal consistency reliability.
