Answer:

(0, 7.5)

Step-by-step explanation:

Compare the equation to the standard-form equation of a circle:

(x -h)^2 +(y -k)^2 = r^2 . . . . . . . center at (h, k); radius r

You will notice that ...

h = 0

k = 7.5

The center is (h, k) = (0, 7.5).

Answer:

Step-by-step explanation:

Given

There are 10 men and 5 women in a conference room

total People=15

(a)Probability that the committee consists of 2 men and 2 women

we have to select from 10 men and 5 women

$P=\frac{^5C_2\times ^{10}C_2}{^{15}C_4}$

(b)Bob and Jane end up on the same committee

as bob and Jane are necessary to include so there are 4 women and 9 men left to select remaining 2 person

$P=\frac{^{13}C_2}{^{15}C_4}$

(c)Bob is in the committee but Jane is not

9 men and 4 women left to choose other 3 person

$P=\frac{^{13}C_3}{^{15C_4}}$
