A company that has 150 employees chooses a committee of 13 to represent employee retirement issues. When the committee is formed, none of the 56 minority employees are selected.
(a) Use technology to find the number of ways 13 employees can be chosen from 150.
(b) Use technology to find the number of ways 13 employees can be chosen from 94 nonminorities.
(c) What is the probability that the committee contains no minorities when the committee is chosen randomly (without bias)?
(d) Does your answer to (c) indicate that the committee selection is biased? Explain your reasoning.

let me know

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
