Use the relationship between the angles in the figure to answer the question. which equation can be used to find the value of x? drag and drop the equation into the box. x = 37 + 53x=90−53x=180−37+53x=90−(37+53)x=1 80−(37+53) two lines and a ray intersect to form 5 angles. starting at the upper left, three angles are labeled 37 degrees, x degrees, and 53 degrees. these angles form a straight line.

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?
