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.

Question

Only need last part

The least-squares regression equation is y = 833.6x + 11,122 where y is the median income and x is the percentage of 25 years and older with at least a bachelor's
degree in the region. The scatter diagram indicates a linear relation between the two variables with a correlation coefficient of 0.7897. Complete parts (a) through (d).
(a) Predict the median income of a region in which 30% of adults 25 years and older have at least a bachelor's degree.
$ 36130 (Round to the nearest dollar as needed.)
(b) In a particular region, 27.6 percent of adults 25 years and older have at least a bachelor's degree. The median income in this region is $30,884. Is this income higher than
This is lower
than expected because the expected income is $ 34129
(Round to the nearest dollar as needed.)
(c) Interpret the slope. Select the correct choice below and fill in the answer box to complete your choice.
