The U.S. Census tracks the percentage of persons 25 years or older who are college graduates. That data forseveral years is given in Table 4[14]. Determine whether the trend appears linear. If so, and assuming the trendcontinues. in what year will the percentage exceed 35%?
The population of a town was recorded every twenty years from 1900 to 2000. The results are shown in the line graph. Assuming that the trend in the population growth continues, which of the following is most likely to be the population of the town in the year 2020?
Monthly sales have been found to follow a linear trend of y = 10 + 8x, where y is the number of items sold and x is the number of the month. Monthly deviations from the trend have been calculated and follow an additive model. In month 12, the seasonal variation is estimated to be -6. What is the forecasted number of items to be sold in month 12?
Part A: What do the x-intercepts and maximum value of the graph represent? What are the intervals where the function is increasing and decreasing, and what do they represent about the sale and profit?Part B: What is an approximate average rate of change of the graph from x = 2 to x = 5, and what does this rate represent?
Earthquakes: The scatterplot below was produced to investigate whether, for the period of observation, the data are consistent with the rate at which earthquakes occur in California remaining constant. 1) Explain why the graph suggests that the average rate at which earthquakes occurred in California was not constant over the period. 2) How did the average rate change over time?
