Which statements are true about y Less-than-or-equal-to 8 and its graph? Check all that apply. y = 0 is part of the solution set. y = 8 is part of the solution set. y = 10 is part of the solution set. There is an open circle on the graph at 8. There is a closed circle on the graph at 8. The arrow on the graph points left. The arrow on the graph points righ

Sample response: if the graph passes the horizontaline test, then the function is one to one. functions that are one to one have inverses that a therefore, the inverse is a hinction compare your response to the sample response above. what did you include in your explanation? a reference to the horizontal-line test d a statement that the function is one-to-one the conclusion that the inverse is a function done

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?
