Answer:

hypergeometric

Step-by-step explanation:

For each winning ticket, there are only two possible outcomes. Either it is held by a men, or it is not.

There is a set number of X, and as the number of winning tickets decrease, the probability of a winning ticket being held by a men can decrease or increase. This is a characteristic of the hypergeometric distribution.

Which point can be found using the vertical line x = –9 and the horizontal line y = 8?
Fudgin [204]
ANSWER

The point is
(-9,8).

EXPLANATION
When two nonparallel lines are drawn on the same plane, they will intersect at a unique point. This point represents the solution to the two systems of equations represented by the lines.

The vertical line
x = - 9

and the horizontal line
y = 8

will intersect at
(-9,8).

This is the unique solution to the two equations.

See graph.
