a.
Use the regression feature of a graphing utility to find a model of the
a.
Answer to Problem 99E
Explanation of Solution
Given information:
The table shows the average high temperatures (in degrees Fahrenheit) in Boston, Massachusetts (B), and Fairbanks, Alaska (F), for selected months in
Use the regression feature of a graphing utility to find a model of the form,
For each city. Let t represent the month, with
Calculation:
Using regression feature of graphing utility for Boston,Massachsettes, the model
The values of,
Now for Fairbanks and ,Alaska, the model
The values of ,
Hence
b.
Use the regression feature of a graphing utility to find a model of the
b.
Answer to Problem 99E
Explanation of Solution
Given information:
The table shows the average high temperatures (in degrees Fahrenheit) in Boston, Massachusetts (B), and Fairbanks, Alaska (F), for selected months in
Use the models from part
Calculation:
According to the model from part
Hence, the temperature of both the cities are,
c.
Use a graphing utility to graph both models in the same viewing window. Compare the temperatures for the two cities.
c.
Answer to Problem 99E
Explanation of Solution
Given information:
The table shows the average high temperatures (in degrees Fahrenheit) in Boston, Massachusetts (B), and Fairbanks, Alaska (F), for selected months in
Use a graphing utility to graph both models in the same viewing window. Compare the temperatures for the two cities.
Calculation:
Use a graphing utility to graph both models in the same viewing window is,
From the graph the maximum temperature of both the cities is same but minimum temperature has huge difference, the fluctuation in temperature of Boston city is less through out the year is less as conpared to Fairbanks.
Hence, in April,May,June both cities almost have same temperature.
