CI is desired for the true average stray-load loss u (watts) for a certain type of induction motor when the line current is held at 10 amps for a speed of 1500 rpm. Assum hat stray-load loss is normally distributed with o = 2.1. (Round your answers to two decimal places.) (a) Compute a 95% CI for u when n = 25 and x = 59.7. 58.88 60.52 watts (b) Compute a 95% CI for u when n = 100 and x = 59.7. 59.29 60.11 watts (c) Compute a 99% CI for u when n = 100 and x = 59.7. 59.16 60.24 watts (d) Compute an 82% CI for u when n = 100 and x = 59.7. 59.42 59.98 watts (e) How large must n be if the width of the 99% interval for u is to be 1.0? (Round your answer up to the nearest whole number.) n = 30
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.
