Use the following information to answer the question. Studies show that since the pandemic started, screen time has increased dramatically. The daily average screen time before the pandemic was mu equal to 100 minutes. A sample of 50 individuals surveyed in the past two weeks produced M equal to 240 minutes and s equal to 110 minutes. Based on the sample, was there a significant increase in the daily average screen time since the pandemic started at the 5% level of significance? How many tails does this test have? one cannot determine two none
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
