1. You are interested in buying a new Jeep Cherokee. The following data are based on information taken from Consumer Guide (Vol. 608, no. 6). Let x be the list price (in thousands of dollars) for a random selection of Jeep Cherokee vehicles of different models and options. Let y be the dealer invoice (in thousands of dollars) for the given vehicle. 15.3 16.4 19.5 21.9 18.8 23.4 Y 14.9 15.8 17.0 18.1 17.1 19.8 Use your calculator. Find the linear regression equation (a is rounded to tenth place and b is rounded to ten-thousandth place). Find the correlation coefficient rounded to ten- thousandth place. Find the coefficient of determination rounded to tenth percent.
Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
