Are 8y=3x+40 and y=8/2x-1 perpendicular

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180

Urgent? will give brainliest to the first correct answer what is the area of the figure?

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?
