The relative frequency of picking a green marble is .
The relative frequency of picking a blue marble is .
The relative frequency of picking a red marble is .
The relative frequency of picking a brown marble is .
The relative frequency of picking a black marble is .
All of the outcomes be considered equally likely.

thus, the first answer choice, y = sec x, is the correct one

explanation:

remove parenthesis:

=

apply rule

=

multiply fractions:

=

=

divide:

=

mordancy.

option a is correct.

only one solution to the system of equations

step-by-step explanation:

if the graph of the equations do not intersects(i.,e if they are parallel) then, there are no solutions that are true for both the equations.

if the graph of the equations intersects, then there is one solution and that is true for both the equations.

since, in the given figure:

the two lines intersect each other

⇒there is only one solution which satisfy both the lines of an equations.

therefore, there is only one solution to the system of equation

you need to know that the corresponding sides and angles are the same.
