Q:

I need help. Attached are pictures of the questions. Very lost. Answers ASAP please. "The table shows latitudes and average temperatures for several cities. Use your calculator to find an equation for a line of best fit. Round your values to the nearest hundredth. Solve this equation to find the temperature in Panama City, Panama (rounded to the nearest whole number), then identify and interpret the correlation coefficient.City Latitude Average Temperature (°F)Calgary, Alberta 51.0°N 24Munich, Germany 48.1°N 26Marseille, France 43.2°N 29St. Louis, Missouri 38.4°N 34Seoul, South Korea37.3°N 36Tokyo, Japan 35.4°N 38New Delhi, India 28.4°N 43Honululu, Hawaii 21.2°N 52Bangkok, Thailand 14.2°N 58Panama City 8.6°N ?The equation is y = .The temperature in Panama City, Panama should be around ____ degrees Fahrenheit.The correlation coefficient r is close to -1 OR close to -0.5 , which indicates a strong correlation OR a weak correlation.

Accepted Solution

A:
Answer: One possible equation is: y = -0.86x + 67.3, that would make the temperature in Panama City 59.9 degrees.

To find a line of best fit, you can select 2 points. Then, find the equation between them.

I choose the points (48.1, 26) and (28.4, 43). The slope between them is -0.86 and the y-intercept would be 67.3. Put those two parts together and you have the equation.

You can also use an online calculator to find the best possible line.
