Answer:
5. OPTION B.
6. OPTION J
Step-by-step explanation:
By definition:
- The Domain is the the set of all the input values. This is the set of all the x-coordinates (remember that the x-coordinate is the first number in each pair).
- The Range is the set of all output values, which is the set of all the y-coordinates ( Remember that the y-coordinate is the second number in each pair).
5. Observe the graph and write the coordinates of each point. These are:
Then, the relation shown in the graph is:
6. Based on the definition shown before, you can determine that the range of the relation shown in the graph is:
Answer:
160:340
Step-by-step explanation:
The hours between 2:00pm and 4:00pm is 2 hours. If originally 350 freshman and 200 sophomores are at the carnival, and 20 freshman leave every hour, we can determine how many freshman left in 2 hours:
and if 35 sophomores arrive every half our, we know that for every two hours there is 4 half hours, therefore:
The amount of freshman at 4:00pm:
and the amount of sophomores:
the ratio is 160:340
