The sample standard deviation between two of the given independent sets is 15.3.

A standard deviation can be defined as the amount of variation or difference between a given set of values. If we have a low standard deviation, it means that the values are closer to the mean of the data set. A higher standard deviation just means that the opposite - the values are far off in the range.

Given data items 84, 85, 83, 63, 61, 100, 98,

Number of data items, N = 7,

Let x represent the data item. The Mean of the data points can be calculated using the -

= 84+ 85+ 83+ 63+ 61+ 100+ 98 / 7

= 82

Hence, the sample standard deviation would be -

Any statistical association between two random variables or bivariate data, whether causal or not, is referred to in statistics as correlation or dependency. Although "correlation" can mean any kind of association in the broadest sense, in statistics it typically refers to the strength of a pair of variables' linear relationships.

In mathematical modelling, statistical modelling, and experimental sciences, there are dependent and independent variables. Dependent variables get their name because, during an experiment, their values are examined under the assumption or requirement that they are dependent on the values of other variables due to some law or rule (for example, a mathematical function). In the context of the experiment in question, independent variables are those that are not perceived as dependant on any other factors.

Answer: To find the solution of the system of equations:

y = 3x^2 + 5x + 4

y = 2x + 10

We set the two expressions for y equal to each other:

3x^2 + 5x + 4 = 2x + 10

Subtracting 2x and 10 from both sides:

3x^2 + 5x - 2x + 4 - 10 = 0

3x^2 + 3x - 6 = 0

We can use the quadratic formula to solve for x:

x = (-b ± √(b^2 - 4ac)) / 2a

Where a = 3, b = 3, and c = -6. Plugging these values into the formula:

x = (-3 ± √(3^2 - 4 * 3 * -6)) / 2 * 3

x = (-3 ± √(9 + 72)) / 6

x = (-3 ± √(81)) / 6

x = (-3 ± 9) / 6

x = (-3 + 9) / 6 or (-3 - 9) / 6

x = 6 / 6 or -12 / 6

x = 1 or -2

The given function is a radical expression with a coefficient of -3, a radicand of x-5, and a constant of 1.

A function is a process or set of instructions that takes inputs, performs a specific task, and produces an output. Functions are key components of programming languages, allowing the coder to create complex commands with simple instructions. For example, a function can be used to add two numbers together or to generate a random number. Functions can also be combined to create more complex sequences of instructions.


This function can be graphed on a coordinate plane by plotting the points that satisfy the equation. The graph of the given function will look like a parabola that is shifted up 1 unit and shifted left 5 units. It can also be seen that this function has been vertically stretched by a factor of 3.

To transform this function, we can use the same rules that apply to linear functions. For example, we can shift the graph up 3 units by adding 3 to the constant of 1, making the new equation f(x) = -3√x-5+4. We can also shift the graph down 5 units by subtracting 5 from the radicand, making the new equation f(x) = -3√x-10+1. Additionally, we can shift the graph left 2 units by subtracting 2 from the radicand, making the new equation f(x) = -3√x-7+1. Finally, we can shift the graph right 4 units by adding 4 to the radicand, making the new equation f(x) = -3√x-1+1.

Overall, by applying the same transformation rules that apply to linear functions, it is possible to transform the given radical expression. The transformation will result in a graph that is shifted up or down, left or right, and vertically stretched or compressed.

We have,

To find the integral of the function g(x) = ∫[0, x] (-34t cos(π/4t²)) dt, we can evaluate the integral using the fundamental theorem of calculus.

The antiderivative of -34t cos(π/4t²) with respect to t can be found by applying the chain rule in reverse.

We set u = π/4t² and find du/dt = -π/2t³.

Rearranging, we have dt = -(2/π) x (1/t³) du.

Substituting back into the integral:

g(x) = ∫[0, x] (-34tcos(π/4t²)) dt

= ∫[0, x] (-34tcos(u)) x -(2/π) x (1/t³) x du

= (68/π) x ∫[0, x] (cos(u)/t²) du.

Now, we can evaluate this integral.

The integral of (cos(u)/t²) with respect to u can be found using basic integration rules:

∫ (cos(u)/t²) du = (1/t²) x ∫ cos(u) du

= (1/t²) x sin(u) + C,

where C is the constant of integration.

Substituting back into the expression for g(x):

g(x) = (68/π)  [(1/t²) sin(u)] evaluated from 0 to x

= (68/π)  [(1/x²)  sin(π/4x²) - (1/0²)  sin(π/4 x 0²)]

= (68/π)  [(1/x²)  sin(π/4x²) - 0]

= (68/π) (1/x²) sin(π/4x²).

By applying the definite integral concept, it can be concluded that ∫₀¹²⁰ r(t) dt represents the number of gallons of oil that leaked from the tank in the first two hours.

Integral is a form of continuous addition that is the inverse of the derivative (anti-derivative)

Definite integral is an integral form in which the integration variables have limits (upper and lower limits) written at the top and bottom of the integral notation.

If y = f(x) is continuous on the interval a ≤ x ≤ b, where a is the lower limit and b is the upper limit, then:

∫ₐᵇ f(x) dx = F(x) |ₐᵇ

The equation of the line is given by:

y = mx + c

The slope m can be found using the formula:

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

where (x1, y1) and (x2, y2) are the two points. Substituting the values, we get:

m = (-2 - 4) / (-3 - 2) = -6/ -5 = 6/5

1. The slope of the secant line in terms of x and h is m(sec) =18x - 6 + 9h.

2. The m(sec) for h= 0.5, 0.1, and 0.01 at x = 1 is 16.5, 12.9 and 12.09 respectively.

3. The equation for the secant line at x = 1 with h = 0.01 is y = 12.09x - 0.09.

The function is g(x) = 9x^2 - 6x + 9

m(sec) = [tex]\frac{g(x+h)-g(h)}{h}[/tex]

m(sec) = [tex]\frac{(9(x+h)^2 - 6(x+h)+9)-(9x^2 - 6x+9))}{h}[/tex]

Simplifying

m(sec) = [tex]\frac{((9x^2+18xh+9h^2) - (6x+6h)+9)-9x^2 + 6x-9)}{h}[/tex]

m(sec) = [tex]\frac{(9x^2+18xh+9h^2 - 6x+6h+9-9x^2 + 6x-9)}{h}[/tex]

m(sec) = [tex]\frac{(18xh+9h^2 +6h)}{h}[/tex]

Taking h common

m(sec) =18x - 6 + 9h

At x = 1

m(sec) =18 - 6 + 9h

m(sec) = 12 + 9h

At h = 0.5

m(0.5) = 12 + 4.5 = 16.5

At h = 0.1

m(0.1) = 12 + .9 = 12.9

At h = 0.01

m(0.01) = 12 + .09 = 12.09

as h = 0 , m(sec) = 12

point-slope form

y - 12 = 12.09(x - 1)

y - 12 = 12.09x - 12.09

Add 12 on both side, we get

y = 12.09x - 0.09

On [0, 2], A(x) can be represented by the linear equation A(x) = (1/2)x.

This means that for every x in the interval [0, 2], the value of A(x) is equal to one-half times x. For example, when x = 1, A(x) = (1/2)x = (1/2) * 1 = 1/2.

On [0, 2], A(x) can be represented by the linear equation A(x) = (1/2)x.

On (2,4], A(x) can be represented by the linear equation A(x) = ((-1/2)x + 2). This means that for every x in the interval (2,4], the value of A(x) is equal to one-half times x minus 2. For example, when x = 3, A(x) = ((-1/2)x + 2) = (-1/2) * 3 + 2 = 2 - 1.5 = 0.5.
