5. If the covariance between the variables x and y is 18 and the variance
klasskru [66]

Answer:

The coefficient of  correlation=0.5

Step-by-step explanation:

We are given that

Covariance between the variable  x and y=18

Variance of x=16

Variance of y=81

We have to find the coefficient of correlation

We know that

Coefficient of correlation

r=\frac{covariance(x,y)}{\sqrt{variance(x)}\times \sqrt{variance(y)}}

Using the formula

r=\frac{18}{\sqrt{16}\times \sqrt{81}}

r=\frac{18}{4\times 9}

r=0.5

Hence, the coefficient of  correlation=0.5

20 POINTS and it has to be correct. This depends on if I pass or fail
valentina_108 [34]

Answer:

(x+8)^{2}+(y-14)^{2}=19

Step-by-step explanation:

The equation of a circle is: (x-x_1)^{2}+(y-y_1)^{2}=r^2 , where x_1 is the x coordinate of the center, y_1 is the y coordinate of the center, and r is the radius.

In this case, x_1 = -8, y_1 = 14, and r = 4.3589. Plugging these into the equation, we get:

(x+8)^{2}+(y-14)^{2}=4.3589^2

If you want, you can round 4.3589^2 to 19.

Then, the answer would be: (x+8)^{2}+(y-14)^{2}=19 .

Hope this helps!

Py+7=6y+q is what in fraction form if anyone can help me<br> I need help bad
algol13
<span>py+7=6y+q does not involve division.  What type of fraction form are you thinking of?

</span><span>py+7=6y+q could be rearranged:  py-6y = q - 7, or y(p-6) = q - 7
                    q - 7
Then y = ------------  This is y in terms of p and q.  But again, I don't know  
                    p - 6     whether this is what you were looking for.  
                                 Please be more specific.</span>
