For online courses, like those in ecore, there is a positive correlation between the amount of time spent in the course and the course grade. the following table presents, for a sample of students in an ecore class, the average number of minutes spent in the course each week (x) and the overall course grade (y). minutes 345.6 360.1 19.8 135.9 217.3 71.1 grade 83.6 95 31.5 73.7 87.1 6.3 compute the least-squares regression line, rounding b0 and b1 to two decimal places. use the least-squares regression line to predict the course grade of a student in the course who spent an average of 103 minutes in the course each week. round your answer to one decimal place. write only a number as your answer.

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?
