The joint relative frequency who like aerobics but dislike weight lifting is $\frac{12}{40}=0.3=30\mathrm{\%}$ , since there are 12 students who like aerobics but dislike weight lifting and there are 40 students in total.

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.

Determine whether each statement makes sense or does not make sense, and explain your reasoning. I’m using a photocopier to reduce an image over and over by 50%,so the exponential function
$f\left(x\right)={\left(\frac{1}{2}\right)}^{x}$ models the new image size, where x is the number of reductions.
