What type of transformation takes the graph of f(x)=|x|f(x)=|x| to the graph of g(x)=2.5|x|g(x)=2.5|x|? vertical shift down of 2.5 vertical stretch by a factor of 2.5 vertical compression by a factor of 2.5 vertical shift up of 2.5

Find the center and the radius of the circle with the equation: x^2-2x+y^2+4y+1=0?

Construct the graph that models the given situation

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?
