Mr. Last's science team is performing an experiment by dropping a water balloon from the roof of a building, 120 feet above the ground. The function used to determine the height of the water balloon as it falls is, h(t) = -16t^2 + c, where (t) stands for time in seconds.
What is the domain and range of the function during this experiment.

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?
