Solve the problem.The paired data below consist of the costs of advertising (in thousands of dollars) and the number of products sold (in thousands). (i) Use a graphing calculator to fit a linear sequence regression function an = an + b to the data, where n is the cost of advertising (in thousands of dollars) and an is number of products sold (in thousands). (ii) Use this function to estimate the number of products sold if the cost of advertising is $14,000.
A. (i) an = 3.02n + 55.8;
(ii) 101.56 thousand products
B. (i) an = 5.79n + 94.3;
(ii) 39,115.8 products
C. (i) an = 2.79n + 55.8;
(ii) 94.86 thousand products
D. (i) an = 2.73n + 34.8;
(ii) 91.86 thousand products

Use a calculator with a 
key or a 
key to solve the problem.Research suggests that the probability of a certain fuse malfunctioning increases exponentially as the concentration of an impurity in the fuse increases. The probability is modeled by the function y = 4(257,911)x, where x is the impurity concentration, and y, given as a percent, is the probability of the fuse malfunctioning. Find the probability of the fuse malfunctioning for an impurity concentration of 0.12. Round to the nearest percent.
