The standard deviation of the distribution of sample means, or the standard error in estimating the mean, is approximately 0.7569 ft, rounded to 4 decimal places.

To find the mean of the distribution of sample means, we use the formula:

Mean of sample means = Mean of the population

In this case, the mean of the population is given as μ = 36.1 ft.

Therefore, the mean of the distribution of sample means is also 36.1 ft.

To find the standard deviation of the distribution of sample means, also known as the standard error, we use the formula:

Standard error = Standard deviation of the population / √(Sample size)

In this case, the standard deviation of the population is given as σ = 6.8 ft, and the sample size is n = 81.

Plugging in these values into the formula, we have:

Standard error = 6.8 / √(81)

Calculating this expression, we find:

Standard error ≈ 0.7569

Therefore, the standard deviation of the distribution of sample means, or the standard error in estimating the mean, is approximately 0.7569 ft, rounded to 4 decimal places.

Answer:

6

Step-by-step explanation:

XY = 3x – 1, YZ = 5, and XZ = 5x – 8,

We know that XY + YZ = XZ, so

3x - 1 + 5 = 5x - 8

3x + 4 = 5x - 8

3x + 12 = 5x

12 = 2x

6 = x

The value of x from the given line segment XZ is 6. Therefore, the correct answer is option A.

Given that, X, Y, and Z are collinear and Y is between X and Z.

Collinear points are those that are on the same straight line or in the same plane. In Euclidean geometry, two or more points on a line that are close to or far from each other are said to be collinear.

So, here \(XZ=XY+YZ\)

\(5x-8=3x-1+5\)

\(5x-8=3x+4\)

\(5x-3x=4+8\)

\(2x=12\)

\(x=6\)

Therefore, the correct answer is option A.

Answer:

The rule to transform \(f(x)\) into \(g(x)\) is:

\(g(x) = 0.8\cdot [f(x-7) - 4]\)

For \(f(x) = x^{2} + 6\cdot x\): \(g(x) = 0.8\cdot x^{2} -6.4\cdot x +2.4\)

Step-by-step explanation:

A vertical translation of a function is described by the following operation:

\(y' = y + k\) (1)

Where:

\(y\) - Original function.

\(y'\) - Translated function.

\(k\) - Vertical translation factor (\(k > 0\) - Upwards)

And a horizontal translation of a function is described by the following operation:

\(y' = f(x-k)\) (2)

Where:

\(x\) - Independent variable.

\(k\) - Horizontal translation factor (\(k > 0\) - Rightwards)

And the dilation of a function is defined by this operation:

\(y' = k\cdot y\) (3)

Where \(k\) is the dilation factor (\(0 < k < 1\) - Contraction)

The rule to transform \(f(x)\) into \(g(x)\) is:

\(g(x) = 0.8\cdot [f(x-7) - 4]\)

If we know that \(f(x) = x^{2} + 6\cdot x\), then \(g(x)\) is:

\(g(x) = 0.8\cdot [(x-7)^{2}+6\cdot (x-7) - 4]\)

\(g(x) = 0.8\cdot [(x^{2}-14\cdot x + 49)+(6\cdot x -42) - 4]\)

\(g(x) = 0.8\cdot (x^{2}-8\cdot x + 3)\)

\(g(x) = 0.8\cdot x^{2} -6.4\cdot x +2.4\)

Answer:

333 cars

Step-by-step explanation:

Assuming among 6 agents, the working efficiency is the same and constant. Fixing number of agents:

    6 agents can sell 333 cars in 3 months.

=> 6 agents can sell 333/3 cars in 3/3 month.

=> 6 agents can sell 111 cars in 1 month.

Fixing number of months:

=> 6/2 agents can sell 111/2 cars in 1 month.

=>  3 agents can sell 111/2 cars in 1 month.

Then considering that 3 agents worked in 6 months:

=> 3 agents can sell 6 x 111/2 cars in 6 x 1 months.

=> 3 agents can sell 333 cars in 6 months.

Real numbers are every  number that exists in the real line, The four types of real numbers are rational, irrational, Natural and Integers.

In mathematics, a real number is a value that can be represented on the number line. The set of real numbers includes both rational numbers (such as integers, fractions, and decimals) and irrational numbers (such as √2 and π). Real numbers also include positive numbers, negative numbers, and zero. The set of real numbers is usually represented by the symbol R, and it has the properties of being closed under the operations of addition, subtraction, multiplication, and division (except for division by zero).

In mathematics, an ideal solution refers to a solution that meets all the desired criteria or requirements without any constraints. It is the "best case" scenario. A real solution, on the other hand, refers to a solution that takes into account all the limitations and constraints of a problem. It is a more practical and realistic solution.

Rational number = 3/4, -6/2, or 0.5.

Irrational number = √2, π, or e.

Natural number = 1,2,3,4....

To find the area of the region bounded by the parabola y = x², the tangent line to this parabola at (1,1), and the x-axis,

we need to use definite integral application.The first step is to find the point of intersection of the tangent line to the curve y = x² at (1,1).The equation of the tangent line can be found by differentiating y = x², which gives us:dy/dx = 2xWe can then substitute x = 1 into the above equation to get the slope of the tangent line at x = 1:dy/dx = 2(1) = 2

Hence, the equation of the tangent line is:

y - 1 = 2(x - 1)

⇒ y = 2x - 1

Now, we can find the point of intersection of this tangent line with the parabola y = x² by setting the two equations equal to each other:

2x - 1 = x²

⇒ x² - 2x + 1 = (x - 1)²

⇒ (x - 1)² = 0⇒ x = 1

Hence, the tangent line intersects the parabola at (1,1).We can now find the area of the region bounded by the parabola, the tangent line, and the x-axis by taking the definite integral of the absolute value of

y = x² - (2x - 1) from x = 0 to x = 1,

since the region is above the x-axis: definite integral of

|y| dx from 0 to 1= ∫₀¹ |x² - (2x - 1)| dx

= ∫₀¹ |x² - 2x + 1| dx

= ∫₀¹ (x - 1)² dx

= [x³/3 - x² + x]

from 0 to 1= (1/3 - 1 + 1) - (0) = 1/3

Therefore, the area of the region is 1/3 square units.

Answer: A good way to get a small standard error is to use a large sample.

Step-by-step explanation:

In order to find the small standard error, there is always need of a complete set which is called the large sample.

If tried to do a small or repeating sample, you will most likely not get an error and you could get a repetition. If you do a population sample, you wont get accurate results at all.

Answer:

Step-by-step explanation:

The standard equation of a given line is expressed as y = mx+c where m is the slope and c is the intercept.

given the function f(x)= 3x − 3, comparing this equation with the standard format, we will have;

mx = 3x

Divide through by x

mx/x = 3x/x

m = 3

Hence the slope of the function f(x)= 3x − 3 is 3.

For a function g(x) passing through the points (0, 2) and (1, 5), to determine the slope, we will use the formula for calculating slope expressed as;

m = Δy/Δx = y₂-y₁/x₂-x₁

From the coordinates, x₁ = 0, y₁ = 2, x₂ = 1, y₂ = 5

m = 5-2/1-0

m = 3/1 = 3

Hence the slope of g(x) passing through the points (0, 2) and (1, 5) is also 3.

This shows that both functions have the same slope.

The product of 56.2 and 9.2057 to the appropriate number of significant digits is 517.00.

The significant digits in a number are the digits that contribute to its precision. When multiplying numbers, the result should be rounded to the same number of significant digits as the factor with the least number of significant digits.

In this case, 56.2 has three significant digits, and 9.2057 has five significant digits. The factor with the least number of significant digits is 56.2. Therefore, the product should be rounded to three significant digits.

Multiplying 56.2 by 9.2057 gives 517.38134. Rounding this result to three significant digits gives us 517.00. The trailing zeros after the decimal point are significant in this case as they indicate the precision of the result. Hence, the correct answer is 517.00.
