Apolitical scientist wants to establish a link between the approval rating for a certain state governor's office and the state's unemployment rate. below is data listing both the approval rating and the unemployment rate over 30 years. use excel to calculate the correlation coefficient r between the two data sets. round your answer to two decimal places.

col1 unemployment: 3.9 3.1 4 4.7 5.4 5.9 8 6.1 7.6 5.5 7.2 5.5 4.2 5.5 5.1 7.9 7.6 5.6 7.2 5.7 4 7.2 5.5 4.3 5.8 5 8.3 4.9 4.9 5.5
col2 approval rating: 38 32 64 59 73 40 57 45 35 60 54 37 53 54 45 32 51 51 36 58 55 39 54 54 46 31 52 52 38 32

Part a what is the area of triangle i? show your calculation. part b triangles i and ii are congruent (of the same size and shape). what is the total area of triangles i and ii? show your calculation. part c what is the area of rectangle i? show your calculation. part d what is the area of rectangle ii? show your calculation. part e rectangles i and iii have the same size and shape. what is the total area of rectangles i and iii? show your calculation. part f what is the total area of all the rectangles? show your calculation. part g what areas do you need to know to find the surface area of the prism? part h what is the surface area of the prism? show your calculation. part i read this statement: “if you multiply the area of one rectangle in the figure by 3, you’ll get the total area of the rectangles.” is this statement true or false? why? part j read this statement: “if you multiply the area of one triangle in the figure by 2, you’ll get the total area of the triangles.” is this statement true or false? why?

The transitive property of equality states that: o if a = b, then bra o if a = b, then ac = bc o if a = b and b= c, then a = if a = b and c= c, then a + b = b + c

Which of the following is the correct equation for this function? a. y= (x+4)(x+2) b. y=x^2+ 3x – 2 c. y+ 2 = – 2(x+3)^2 d. y+ 2 = 2(x+3)^2
