Answer:

(-2,-1)

Step-by-step explanation:

If you look at the graph, you can see that the lines will extend upwards indefinitely, but the lines will stop going downwards at y = -1

When y = -1, x = -2

Therefore, the values of x for the given values of y when y<0 is (-2,-1)

It is estimated that only 68% of drivers wear their safety belt. How many people should a police officer expect pull over until

e-lub [12.9K]

Answer:

D. 4

Step-by-step explanation:

Percent of drivers who wear seat belts = 68

Percent of drivers who do not wear seat belts = 100 - 68 = 32

Now, we know that for every 100 pull overs, 32 drivers will not be wearing belt.

32 drivers without seat-belt = 100 pullovers

1 driver without seat-belt = 100/32 pullovers

1 driver without seat-belt = 3.125 pullovers (4 pullovers)

So, a police officer should expect 4 pullovers until she finds a driver not wearing a seat-belt.

first:

$\left(\frac{1}{4}+1\frac{1}{2}\right)\cdot \frac{1}{2} =\left(\frac{1}{4}+\frac{3}{2}\right)\cdot \frac{1}{2} =\frac{\left(\frac{1}{4}+\frac{3}{2}\right)\cdot \:1}{2} =\frac{\left(\frac{1}{4}+\frac{6}{4}\right)\cdot \:1}{2} =\frac{\frac{7}{4}\cdot \:1}{2} =\frac{\frac{7}{4}}{2} =\frac{7}{4\cdot \:2} =\frac{7}{8}$
