Answer:
Step-by-step explanation:
In combinatorics, the rule of product states that if there are ways of doing one thing and
ways of doing another thing, then there are
ways of performing both actions.
In this case, if there are 7 ways of getting from town A to town B, and 8 ways of getting from town B to town C, then there are ways of getting from town A to town C via town B.

Answer:
(B) Time (min) 2 , 3 , 7 , 9
Temperature (°C) 60.6 , 64.3 , 79.1 , 86.5
Step-by-step explanation:
The rate of change is found by using the formula for slope:
For option A, this gives us
m =(64.4-61.0)/(3-2) = 3.4/1 = 3.4
This is not more than relationship A.
For option B, we have
(64.3-60.6)/(3-2) = 3.7/1 = 3.7
This is more than relationship A.
For option C, we have
(65.3-61.8)/(3-2) = 3.5/1 = 3.5
This is not more than relationship A.
For option D, we have
(64.6-61.0)/(3-2) = 3.6/1 = 3.6
This is not more than relationship A.
