Step-by-step explanation:
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

Using the formula



Hence, the coefficient of correlation=0.5
Answer:

Step-by-step explanation:
The equation of a circle is:
, 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:

If you want, you can round 4.3589^2 to 19.
Then, the answer would be:
.

<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>
