Answer:

3/4 or 9/12

Step-by-step explanation:

Since there are 12 movies in total. The possible chance of picking a drama movie is a 1 out of 4 chance (3/12 = 1/4), the possible of picking a movie without a drama is a 3 out of 4 chance (9/12 = 3/4)

12/12 - 3/12 = 9/12 = 3/4

Solve the inequality. Graph the solution on a number line. 7 ≥ t/-2

Elodia [21]

$t\geq -14$

The graph is shown in the figure attached.

Step-by-step explanation:

We need to solve the inequality $7\geq \frac{t}{-2}$ and graph the solution.

Solving the inequality: $7\geq \frac{t}{-2}$

Switch sides and reverse the inequality:

$\frac{t}{-2}\leq 7$

Multiplying both sides by -2 and reverse the inequality

$-2\frac{t}{-2}\geq 7*-2$

$t\geq -14$

The graph is shown in the figure attached.
