There are 21 students who like weight lifting and there are 40 student in total so the marginal relative frequency is $\frac{21}{40}=52.5\mathrm{\%}$

The population of California was 29.76 million in 1990 and 33.87 million in 2000. Assume that the population grows exponentially.

(a) Find a function that models the population t years after 1990.

(b) Find the time required for the population to double.

(c) Use the function from part (a) to predict the population of California in the year 2010. Look up California’s actual population in 2010, and compare.

In addition to quadratic and exponential models, another common type of model is called a power model. Power models are models in the form $\hat{y}=a\cdot {x}^{p}.$ Here are data on the eight planets of our solar system. Distance from the sun is measured in astronomical units (AU), the average distance Earth is from the sun.
