The speed of sound through air is linearly related to the temperature of the air. If sound travels at 320 m/ sec at 0°C and at 326 m/sec at 20°C, construct a linear model relating the speed of sound (s) and the air temperature (t). Interpret the slope of this model. Construct a linear model relating the speed of sound (s) and the air temperature (t). s= 0.3t + 320

5c please answer the C

The table lists fossil fuel production as a percentage of total energy production for selected years. A linear regression (A) Draw a scatter plot of the data and a graph of the model on the same axes. model for this data is O A. O B. y = - 0.22x + 97.2 where x represents years after 1960 and y represents the corresponding percentage of oil imports. 100- 100- Fossil Fuel Production Year Production (%) 0- 1960 96 60 60 1970 95 Years after 1960 Years after 1960 1980 94 1990 93 2000 86 100- 100- 0- 60 60 Years after 1960 Years after 1960 (B) Interpret the slope of the model. The rate of change of the percentage of oil imports with respect to time is -0.22% per year. (C) Use the model to predict fossil fuel production in 2010. In 2010 fossil fuel production as a percentage of total production will be about %. (Round to one decimal place as needed.)
