Answer:

f(-4) = 9

Step-by-step explanation:

To find which expression to use, see which one x = -4 fits in. That is <em>x² - 5</em>, since -4 < 3.

Then, plug in the number: (-4)² - 5

Square: 16 - 5

Subtract: 9

f(-4) = 9

Answer:

P(\text{Male}|\text{Divorced})\approx0.092

Step-by-step explanation:

\displaystyle P(\text{Male}|\text{Divorced})=\frac{P(\text{Male and Divorced})}{P(\text{Male})}=\frac{\frac{9.6}{214.7}}{\frac{104.5}{214.7}}\approx0.092

We can even break this down further by simply only looking at the total amount of males, and finding the proportion of males that are divorced, which is \frac{9.6}{104.5}\approx0.092, the same value.

Note that P(Male | Divorced) means the probability of choosing a male, given (|) that person is divorced.
