Answer:

X(4, 6) Y(2, 3) Z(6, 7)

Step-by-step explanation:

If you want to translate something right on a number line, then you are essentially adding to it. Thus you would just add 2 to each of the x values of the coordinates. The same applies with translating something up, all that really means is that you are adding to each of the y values so all you have to do is add 3 to each of the y values and you get your answer.

Answer:

X:(4,6), Y:(2,3), Z:(6,7)

Step-by-step explanation:

2 units right implies a change on the x-axis, meaning you add 2 units to the x of the coordinate pair (x, y). 3 units up implies a change in Y, you apply the same rule and add 3 to the Y of the pair.

2 units right (add 2 to x pair coordinate)

X: (2,3) --> (4,3)

Y: (0,0) --> (2,0)

Z:(4,4) --> (6,4)

and 3 units up (add 3 to y pair coordinate)

X: (4,3) --> (4,6)

Y: (2,0) --> (2,3)

Z: (6,4) --> (6,7)

Historical scientists deal with falsification by rigorously analyzing evidence, using peer review and scholarly discourse, and revising hypotheses based on new discoveries and interpretations.



Historical scientists deal with falsification by employing rigorous methodologies and critical analysis of evidence. They strive to gather as much relevant data as possible to test hypotheses and theories. This is done through meticulous research, including the examination of primary sources, archaeological artifacts, historical records, and other forms of evidence. Historical scientists also engage in peer review and scholarly discourse to subject their findings to scrutiny and criticism.

The mechanism used by historical scientists to falsify hypotheses involves a combination of evidence-based reasoning and the application of established principles of historical analysis. They aim to construct coherent and logical explanations that are supported by the available evidence. If a hypothesis fails to withstand scrutiny or is contradicted by new evidence, it is considered falsified or in need of revision. Historical scientists constantly reassess and refine their hypotheses based on new discoveries, reinterpretation of existing evidence, and advancements in research techniques. This iterative process helps to refine our understanding of the past and ensures that historical knowledge remains dynamic and subject to revision.

Therefore, Historical scientists deal with falsification by rigorously analyzing evidence, using peer review and scholarly discourse, and revising hypotheses based on new discoveries and interpretations.

There is insufficient evidence of a significant difference in the proportion of males and females that have at least one tattoo.

Therefore, the correct answer is A.

To construct a confidence interval for the difference in proportions, we can use the following formula:

CI = (p1 - p2) ± Z ×√[(p1×(1 - p1) / n1) + (p2 × (1 - p2) / n2)]

Where:

p1 and p2 are the sample proportions for males and females, respectively.

n1 and n2 are the sample sizes for males and females, respectively.

Z is the critical value corresponding to the desired confidence level.

From the given information, we have:

p1 = 190/1233

n1 = 1233

p2 = 128/1033

n2 = 1033

Confidence level = 99% (which corresponds to a critical value of Z)

Calculating the confidence interval:

CI = (190/1233 - 128/1033) ± Z× √[(190/1233× (1 - 190/1233) / 1233) + (128/1033 ×(1 - 128/1033) / 1033)]

Now, let's find the critical value Z for a 99% confidence level. Since the sample sizes are large, we can use the standard normal distribution. The critical value for a 99% confidence level is approximately 2.576.

CI = (0.154 - 0.124) ± 2.576× √[(0.154× (1 - 0.154) / 1233) + (0.124 × (1 - 0.124) / 1033)]

CI = 0.030 ± 2.576×√[0.000118 + 0.000124]

CI = 0.030 ± 2.576×√(0.000242)

CI = 0.030 ± 2.576×0.015556

CI = 0.030 ± 0.040085

CI ≈ (-0.010, 0.070)

The lower bound of the 99% confidence interval is approximately -0.010, and the upper bound is approximately 0.070.

Interpreting the interval, we can say:

A. There is 99% confidence that the difference of the proportions is in the interval. Conclude that there is insufficient evidence of a significant difference in the proportion of males and females that have at least one tattoo.

Therefore, the correct answer is A.

Answer:

The rule is: y = -10x+85

Step-by-step explanation:

The rule is given by:

\(y = mx+b\)

Here m is the gradient and b is the y-intercept.

We have to take two pairs of input-output to find the rule

Let the two pairs be:

(x1,y1) = (1,75)

(x2,y2) = (2,65)

Slope is found using the formula:

\(m = \frac{y_2-y_1}{x_2-x_1}\)

Putting the values

\(m = \frac{65-75}{2-1}\\m = -10\)

Putting the value of slope

\(y = -10x+b\)

Putting a pair of input-output in the equation (1,75)

\(75 = -10(1) +b\\75 = -10+b\\b = 75+10\\b = 85\)

Putting the value of b

\(y = -10x+85\)

Hence,

The rule is: y = -10x+85

To convert Decimal into Fraction form:

Do the following Steps:

Step 1: Make a fraction with the decimal number as the numerator and a 1 as the denominator.

Step 2: Remove the decimal places by multiplication.

Step 3: Reduce the fraction.

Step 4: Simplify the remaining fraction to a mixed number fraction if possible.

Given,

The smallest flowering plant is the flowering aquatic duckweed found in Australia.

And it is 0.0236 inch long and 0.0129 inch wide.

\(\huge\text{$m\angle O=\boxed{11^{\circ}}$}\)

Since we know that all angles in a triangle add up to \(180^{\circ}\), we can solve for \(x\) and substitute it back into \((x-5)^{\circ}\) to find \(m\angle O\).

\(\begin{aligned}m\angle N+m\angle O+m\angle P&=180\\(5x-8)+(x-5)+(6x+1)&=180\end{aligned}\)

Remove the parentheses and combine like terms.

\(\begin{aligned}5x-8+x-5+6x+1&=180\\(5x+x+6x)+(-8-5+1)&=180\\12x-12&=180\end{aligned}\)

Add \(12\) to both sides of the equation.

\(\begin{aligned}12x-12&=180\\12x&=192\end{aligned}\)

Divide both sides of the equation by \(12\).

\(\begin{aligned}x=16\end{aligned}\)

Now that we have the value of \(x\), we can substitute it back into \((x-5)^{\circ}\) to find \(m\angle O\).

The determinant of the matrix a with 8's on the diagonal, 1's above the diagonal, and 0's below the diagonal is det(a) = 8ⁿ, where n is the dimension of the matrix.

To find the determinant of the n×n matrix a with 8's on the diagonal, 1's above the diagonal, and 0's below the diagonal, we can use the property that the determinant of a triangular matrix is equal to the product of its diagonal elements.

Since the matrix a is an upper triangular matrix, its determinant is the product of its diagonal elements.

The diagonal elements of matrix a are all 8's. Therefore, the determinant of matrix a can be computed as follows:

det(a) = 8 * 8 * 8 * ... * 8 (n times)

      = 8ⁿ

Hence, the determinant of the matrix a is 8 raised to the power of n (det(a) = 8ⁿ).

This means that the determinant of matrix a is simply 8 raised to the power of the dimension of the matrix (n).

The specific values of the elements above and below the diagonal (1's and 0's, respectively) do not affect the determinant, as they do not contribute to the product when computing the determinant of an upper triangular matrix.

In summary, the determinant of matrix a is det(a) = 8ⁿ, where n represents the dimension of the matrix.

a. It is true that the sample standard deviation s is 2.

b. The one-sided lower 90% confidence bound for μ is ≈ 2.38

c. We can not claim that > 3 with 90% confidence.

The sample standard deviation s is given by the formula

\(s =sqrt [Σ(xi - x)^2 / (n - 1)]\)

The sample mean is:

x = (2 + 4 + 6) / 3 = 4

The deviations from the mean are:

2 - 4 = -2

4 - 4 = 0

6 - 4 = 2

The sum of squared deviations is:

\((-2)^2 + 0^2 + 2^2 = 8\)

Therefore, the sample standard deviation is:

s = sqrt[8 / (3 - 1)]

= sqrt(4) = 2

To calculate the one-sided lower 90% confidence bound for the population mean μ

x - (tα,n-1) * s / sqrt(n)

For a one-sided lower confidence bound with α = 0.1 and n = 3, we have:

t0.1,2 ≈ 1.886

Therefore, the one-sided lower 90% confidence bound for μ is:

x - (t0.1,2) * s / sqrt(n) = 4 - 1.886 * 2 / sqrt(3)

≈ 2.38

To test the hypothesis that μ > 3 with 90% confidence

Compare the claimed value of μ to the one-sided lower 90% confidence bound from part (b). If the claimed value is greater than the confidence bound, we reject the claim with 90% confidence.

In this case, the one-sided lower 90% confidence bound of 2.38 is less than μ is 3.

Therefore, we can reject the claim that μ > 3 with 90% confidence.
