The midpoint of a sègment is (6,-4) and one endpoint is (13,-2). Find the coordinates of the other endpoint.

gizmo_the_mogwai [7]

let other one be (x,y)

We know midpoint formula

$\boxed{\sf (x,y)=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)}$

$\\ \sf\longmapsto (6,-4)=\left(\dfrac{13+x}{2},\dfrac{-2+y}{2}\right)$

$\\ \sf\longmapsto \dfrac{13+x}{2}=6$

$\\ \sf\longmapsto 13+x=12$

$\\ \sf\longmapsto x=12-13$

$\\ \sf\longmapsto x=-1$

And

$\\ \sf\longmapsto \dfrac{-2+y}{2}=-4$

$\\ \sf\longmapsto -2+y=-8$

$\\ \sf\longmapsto y=-8+2$

$\\ \sf\longmapsto y=-6$

The Wall Street Journal Corporate Perceptions Study surveys readers and asks how each rats the quality of management and the rep

ololo11 [35]

Answer:

Step-by-step explanation:

$\text{The data given for the quality measurement and other criteria can be seen below:}$

Quality management Excellent Good Fair Total

Excellent 40 25 5 70

Good 35 35 10 80

Fair 25 10 15 50

Total 100 70 30 200

The null and alternative hypothesis:

$\mathbf{H_o: \text{the quality management and reputation are independent} }$

$\mathbf{H_a: \text{the quality management and reputation are not independent} }$

The expected value is calculated by using the formula:

$E=\dfrac{row \ total \times column \ total }{table \ total}$

After using the formula to calculate the table above; we have:

The expected values of the data to be:

Quality management Excellent Good Fair Total

Excellent 35 24.5 10.5 70

Good 40 28 1.2 80

Fair 25 17.5 7.5 50

Total 100 70 30 200

Degree of freedom = ( row - 1 ) × ( column -1 )

$= (3 - 1 ) \times (3 -1)$

$= 2\times 2$

$=4$

$\text{The p-value at level of significance of 0.05 and degree of freedom of 4 = }\mathbf{0.0019}$

Decision rule: To reject the $\mathbf{H_o}$ if the p-value is less than the ∝

Conclusion: We reject the $\mathbf{H_o}$ and conclude that quality management and reputation are not independent.

(B) $\text{The P-value here implies that in case that there is no dependence between the two ratings, }$ $\text{the probability that they will seem to show at least this kind of strong dependence is 0.0019.}$

$\text{Thus, the probability that they will seem to show at least this kind of strong independence is =}$ $\mathbf{0.0019}$
