A study was conducted to determine the effect of weather on varieties of corn grown for grazing by cattle in Alberta,Canada.To conduct the study,five varieties of corn were considered (one grazing,one short-stature,and three conventional)with harvesting of crops conducted on four occasions (two dates in September,one in December,and one in January).The experimental treatments were assigned at random to plots of land at each of two different locations in Alberta in order to control for natural variations in location.The crude protein concentration of the harvested corn was determined. In this experiment the factor(s),number of treatments,and the response are

Forman and Brasso Furniture Company had net income of $34,000 and net sales of $248,800. Compute the relationship of net income to net sales. Express your answer as a percentage. (Round answer to two decimal places.)

The population of a region for 2000 is 282.2 (in millions) . The predicted population (in millions) for the region in the year 2020 is 355.5. Calculate the constants C (to one decimal place) and k (to four decimal places) to obtain the experimental growth model $y=C{e}^{kt}$ for the population. (Let $t=0$ correspond to the year 2000.) What does the model predict the population will be in 2030? Round your answer to one decimal place.

A) 399.0 million
B) 282.2 million
C) 103.8 million
D) 392.2 million
