Sara's cat-walking service charges a flat rate of $15 per month, plus $2 per mile that each cat is walked. Nicole charges a flat rate of $10 per month plus
$4 per mile that each cat is walked. Write and solve an equation to find the
number of miles m for which Sara anc-Nicole would charge the same amount.

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
