Write x2 + y2 – 18x + 8y + 5 = 0 in standard form. Group terms and move the constant to the other side of the equation. x2 – 18x + y2 + 8y = –5 Determine the values that need to be added to both sides of the equation. (–18 ÷ 2)2 = 81 and (8 ÷ 2)2 = 16 Add the values to both sides of the equation. Write each trinomial as a binomial squared, and simplify the right side. What is the standard form of the equation of a circle given by x2 + y2 – 18x + 8y + 5 = 0? ()² + ()² =

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
