A committee of 4 4
is being formed randomly from the employees at a school: 6
6
administrators, 36
36
teachers, and 5
5
staff. What is the probability that all 4
4
members are administrators? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
