Answer:

5. D

7. B

9. A

Explanation:

5.

The probability of an event happening is a number from 0 to 1 with the following meaning:

probability of event equals:

0 - event will definitely not happen

1 - event will definitely happen

0.5 - event is as likely to happen as it is likely to not happen

From 0 - 0.5 - event is more likely to not happen.

From 0.5 - 1 - event is more likely to happen.

Here, all numbers are 0, 1 or a number in between 0 and 1, so all are possible probabilities.

Answer: D

7.

3y × 1/y + 6y² + y + 4 =

= 3 + 6y² + y + 4

= 6y² + y + 7

The constant term is 7.

Answer: B

9.

The ratio is 7:4.

One part is x.

The other part is x + 20.

Since x + 20 > x, then x + 20 corresponds to 7 in the ratio, and x corresponds to 4 in the ratio.

(x + 20)/x = 7/4

Answer: A.
