If a ship sailed due south from iceland to antarctica, it would sail through an angle of rotation of about 140 degrees around earth's center. find this measure in radians. then, using 3960 miles for earth's radius, find how far the ship would travel

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²

Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
