The third choice is very useful. It's valid because two things that are both equal to 'y' are equal to each other, and it can be easily solved to find 'x'.
Answer:
add both of those up and see what you get
Step-by-step explanation:
Part A:
- Each dollar spent DOES appear to always have the same number of points.
This is correct because it has a set rate of 10 points per dollar.
- Predicted number of points spent for $9:
$9 * 10 = $90
Part B:
- It DOES appear to take the same amount of time to serve each customer.
This is correct because it has a set rate of 4 minutes per customer.
- Predicted number of customers served in 36 minutes: 36/4= 9 customers.
Hope this helps!
Mode, is very easy to understand.
You have a list of numbers; 1,2,3,4,5,5,4,5
You have the question, "What is the Mode for this list of numbers?"
First off, what is Mode?
Mode is the value (number) that appears most often in a set of data. That being said, go back to the list given above.
1,2,3,4,5,5,4,5
The numbers that appear most often is 4 and 5.
4 appears 2 times
5 appears 3 times
But, remember, Mode is the value that appears most OFTEN;
Thus, the Mode for this example is 5.
