The phone rings and the President is calling you. He says "I hear you are studying correlation. Can you tell me how much of the variability in my popularity ratings is explained by the unemployment rate?" He kindly supplies you with the following data from five different statesPopularity Unemployment Ratings Rate 70 10 75 1285 884 648 14What percent of the variance in his popularity ratings is accounted for by the state unemployment rate?

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
