Answer:
(-4,-11)
Step-by-step explanation:
Given an equation of a circle
To find the centre and radius of the circle.
We group x terms to gether and y terms to gether first.
Now completion of squares method is used for both x and y.
Thus we find that the centre = (-4,-11) and radius
= 10

Determine the probability of selecting a woman
The given data can be represented to show women distribution as:
-------------------------------------- Women ------------------- Total
Assistant Professors ----------- 108 ----------------------253
Associate Professors ---------97 -------------------------301
Full Professors -----------------78---------------------------350
First, we calculate the number of women
Next, we calculate the total number of professors
Probability of selecting women is then calculated as:
