CHOOSE ONE system of equations, A, B, or C to use for the following questions:

A) Linear Equation: y = -x + 1
Parabolic Equation: y = x2 + x - 2

B) Linear Equation: y = 2x + 1
Parabolic Equation: y = x2 - 5x + 7

C) Linear Equation: y = -2x + 2
Parabolic Equation: y = -x2 + 2x + 7

Show all work to solve your system of equations algebraically.

I chose B

Task 1: Part 2

Graph your system of equations and show the solution graphically to verify your solution.

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?
