Answer:

k=-3

x=63

Step-by-step explanation:

The equation for direct variation is

y = kx where k is the constant of variation

We know x and y we can solve for k

-87 = k*29

Divide each side by 29

-87/29 = k

-3 =k

y= -3x

Now we know y = -189, we can find x

-189 = -3x

Divide by -3

-189/-3 = -3x/-3

63 =x

There are 9 candidates total, 5 male and 4 female, who run for 4 committee positions. Suppose that each person is equally likely

gavmur [86]

Use the hypergeometric distribution.
M=number of Men=5
F=number of women=4
m=number of men elected=2
f=number ow women elected=2.

Assuming equal chance to get elected, then
P(2M,2F)=C(M,m)*C(F,f)/C(M+F,m+f)
=C(5,2)*C(4,2)/C(9,4)
=10*6/126
=10/21
