Nora tracked variations in temperature for five days to show how much above or below average the actual temperature was.

Question

A 5-column table with 1 row titled Degrees Above/Below Average (Fahrenheit). Column 1 is labeled Monday with entry 2.2. Column 2 is labeled Tuesday with entry negative one-half. Column 3 is labeled Wednesday with entry negative 1 and one-half. Column 4 is labeled Thursday with entry negative 0.9. Column 5 is labeled Friday with entry 1. A number line going from negative 3 to positive 3.

Graph the data on the number line.

On which day was the temperature the farthest below average?

Answer 1

To graph the data on the number line:

1. First, we convert the temperatures for Tuesday and Wednesday into decimal form for easier plotting:

   • Tuesday: -1/2 = -0.5
   • Wednesday: -1.5 (same as written)
   • Thursday: -0.9 (same as written)

2. Now we have the following list of values:

   • Monday: 2.2
   • Tuesday: -0.5
   • Wednesday: -1.5
   • Thursday: -0.9
   • Friday: 1

3. Next, we can plot these temperatures on the number line ranging from -3 to +3:

   • Monday (2.2): Place a point slightly less than 2.5, between 2 and 3.
   • Tuesday (-0.5): Place a point between -1 and 0.
   • Wednesday (-1.5): Place a point halfway between -1 and -2.
   • Thursday (-0.9): Place a point slightly less than -0.5, between -1 and 0.
   • Friday (1): Place a point slightly less than 1.5, between 1 and 2.

4. Once plotted on the number line, you can see the relative positions of the points.

To answer the second part of the question:

• On which day was the temperature the farthest below average?
  • Looking at the values:
    • Tuesday: -0.5
    • Wednesday: -1.5
    • Thursday: -0.9

The temperature was the farthest below average on Wednesday, with a temperature of -1.5 degrees.
