linear programming models

Name the type of model suggested by the graph. => Linear model or Exponential model or Cubic model or Quadratic model..

The scatter plot shows the change in gravity (rounded to the nearest tenth) as the altitude changes. State whether it is reasonable for the graph to be represented by a linear model. Which method can be used to find the change in gravity at an altitude of 300 km? => no, lin..

From 1990, the production of wheat was increasing by 3 thousand tons every year. In the year 1995, the total production of wheat was 30 thousand tons. Find the slope of the linear model for the situation. => 5 or 4 or 3 or 2..

The table shows the number of passengers who traveled from New York to Seattle between 1960-1965. Is it reasonable to represent the data by a linear model? Which method can be used to estimate the number of passengers who traveled in the year 1968? => yes, linear inter..

From 1990, the production of wheat increased by 4 thousand tons every year. In the year 1995, the total production of wheat was 47 thousand tons. Write a linear model for the production of wheat p over the years t . => p = -4 t - 27 or p = -4 t + 27 or p = 4 t + 27 or p = 4 t - ..

Write a linear model that represents the total number of legs of x bears and y Vultures, if the total legs of bears and Vultures is 240. => 4 x + 2 y = 240 or 2 x + 4 y = 240 or x + 2 y = 240 or None of the above..

The productivity of an oil plant increases by 5 barrels every month in a particular year. The total number of barrels produced by the plant by the 7 th month is 35 barrels. Write a linear model for the number of barrels b produced over the months p . => b = -7 p or b = 7 p or b ..

From 1990 to 2000, the number of schools in California increased at the rate of 20 schools per year. In 2000, there were 1200 schools in the city. Write a linear equation that models the number of schools y and estimate the number of schools in the year 2005. Let x = 0 represent..

From 1980 to 2000, the price of crude oil increased by $4 per barrel per decade(10 years.) In the year 2000, the price of crude oil was $60. Write a linear model for the price per gallon of crude oil, p over the number of decades t . => p = 52 t - 4 or p = 4 t - 52 or p = 4 t + ..
