The mean unemployment rate in January of each year from 1995 to 2004 is x = 5.06, with a standard deviation of sx = 1.2. The mean unemployment rate in June of each year for the same time frame is = 5.09, with a standard deviation of sy = 0.9. The correlation coefficient is r = 0.89.
Part A: Find the equation of the least-squares regression line for predicting June's unemployment rate from January's unemployment rate. Show your work. (3 points)
Part B: Use the regression line to predict the unemployment rate if January's rate is 4.3. Show your work. (3 points)
Part C: Find and interpret r-squared. (4 points)

the answer is stop cheating on things stoopid

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
