Answer: see image

<u>Step-by-step explanation:</u>

Draw line x = 3. Count how many units each point is away from line x = 3. Plot the new point the same number of units away from line x = 3 but in the opposite direction.

Point G is 4 units to the left of x = 3. The new point G' is 4 units to the right of x = 3.

Point F is 7 units to the left of x = 3. The new point G' is 7 units to the right of x = 3.

Point E is 7 units to the left of x = 3. The new point G' is 7 units to the right of x = 3.

Point H is 4 units to the left of x = 3. The new point G' is 4 units to the right of x = 3.

An article gave the following summary information for fracture strengths (MPa) of n = 196 ceramic bars fired in a particular kil

Oliga [24]

Answer:

54.80 MPa to 55.92 MPa

Step-by-step explanation:

Sample mean fracture strength (x) = 55.36 MPa

Sample standard deviation (s) = 3.99 MPa

Sample size (n) = 196.

The upper and lower bounds for a 95% confidence interval are given by:

$U=x+1.960*\frac{s}{\sqrt{n}} \\L=x-1.960*\frac{s}{\sqrt{n}}$

The upper and lower bounds of the confidence interval are;

$U=55.36+1.960*\frac{3.99}{\sqrt{196}}\\U= 55.92\\L=55.36-1.960*\frac{3.99}{\sqrt{196}}\\L= 54.80\\$

The 95% confidence interval for true average fracture strength is 54.80 MPa to 55.92 MPa

Please help me am I. troubles

Zanzabum

Answer:

$\frac{ {x}^{2} }{y(x - y)} + \frac{ {y}^{2} }{ - x(x - y)}$

$\frac{ {x}^{2} }{y(x - y)} - \frac{ {y}^{2} }{x(x - y)}$

$\frac{ {x}^{2} \times x - {y}^{2} \times y}{xy(x -y)}$

$\frac{(x - y)( {x}^{2} + xy + {y}^{2}) }{xy(x - y)}$

$\frac{ {x}^{2} + xy + {y}^{2} }{xy}$

PLEASE HELP! - The scatterplot below shows the number of weeks that students have been in keyboarding class and the number of mi

Setler [38]

Solution: Which statement about the scatter plot is true?

The correct answer is option A. As the number of weeks in class increases, the number of keyboarding mistakes decreases.

Explanation: From the scatter plot, we clearly see there exists a negative linear relationship between the number of weeks in class and the number of mistakes. And we know that if there exists a negative linear relationship between the two variables, then the values of two variables move in opposite direction. If the values of one variable goes up, the values of other variable go down. From the given scatter plot, we clearly see the number of mistakes goes down as the number of weeks in class increases. Therefore, the option A is correct
