En una caja que contiene 4 corbatas negras 5 azules y 6 verdes. Se extraen al mismo tiempo dos corbatas al azar. ¿Cuál es la probabilidad de que ambas sean negras? cuel de estas son ? 15/3, 15/4, 16/210, 10/12

If the graphs of the linear equations in a system are parallel, what does that mean about the possible solution(s) of the system? a. there are infinitely many solutions. b. there is no solution. c. there is exactly one solution. d. the lines in a system cannot be parallel.

To prove that def ~ gfh by the sss similarity theorem using the information provided in the diagram, it would be enough additional information to know that

What will the graph look like for a system of equations that has no solution? a. the lines will be perpendicular. b. the lines will cross at one point. c. both equations will form the same line. d. the lines will be parallel.
