Find the best approximation of this function, using least squares.tw = w(h, a, 9) =!3!!!

We use multiple linear regression in some spreadsheets. We can use google sheets for this.

Meat Consumption The U.S. per capita consumption (in pounds) of beef, pork, and chicken for 2000 and 2012 is given in the following table. Assume that the changes in consump- tion are approximately linear. Source: U.S. Department of Agriculture. 2000 2012 Beef 64.5 54.5 Pork 47.8 42.6 Chicken 54.2 56.6 (a) Determine three linear functions, b(t), p(t), and c(t), which approximate the pounds of beef, pork, and chicken, respectively, consumed for time t, where t is the number of years since 2000. (b) Describe the rates at which the consumption of each type of meat is changing. (c) In what year did the consumption of chicken surpass the consumption of beef? (d) If these trends were to continue, approximate the con- sumption of each type of meat in 2015.
Marine scientists use a linear model for the speed c of sound in the oceans as a function of the salinity S at a fixed depth and temperature.† In the following table, one scientist recorded data for c and S at a depth of 500 meters and a temperature of 15 degrees Celsius. Here c is measured in meters per second and S in parts per thousand. Salinity S Sound speed c 35.0 1515.36 35.6 1516.08 36.2 1516.80 36.8 1517.62 37.4 1518.24 (a) Looking over the table, the scientist realizes that one of the entries for sound speed is in error. Which entry is it?S = What is the correct speed?c = m/sec(b) Explain in practical terms the meaning of the slope of the linear model for c in terms of S at the given depth and temperature. The slope means that, at the given depth and temperature, for an increase in salinity of part per thousand the speed of sound increases by meters per second. (c) Calculate c(38.2).c(38.2) = m/secExplain in practical terms what it means. This means…
