Answer:

Step-by-step explanation:
There are a total of 7 + 9 + 2 = 18 balls in the vase, therefore, when not replacing the first ball, there would be 18 · 17 = 306 ways to pull 2 balls. There are 2 ways to choose the first black ball and then 1 way to choose the second black ball so there are 2 · 1 = 2 ways to choose 2 black balls. Therefore, the probability is 2 / 306 =
.
The unit rate is the amount of book copy made in a second
The table that represents the unit rate is table (b)
<h3>How to determine the table?</h3>
The interpretation of the diagram for making copies is:
Rate = 4 copies per second
This means that:
The table that represents this diagram must have a slope or rate of 4
From the list of options, the table (b) has a slope of 4.
This is calculated as:
Slope = Copies/Time
So, we have:
Slope = 40/10 = 4
Hence, the table that represents the unit rate is table (b)
