A certain group of test subjects had pulse rates with a mean of 72.9 beats per minute and a standard deviation of 12.1 beats per minute. Use the range rule of thumb to identify the limits separating values that are significantly low or significantly high. Is a pulse rate of 67.1 beats per minute significantly low or significantly high? Significantly low values are 48.7 beats per minute or lower. (Type an integer or a decimal. Do not round.) Significantly high values are beats per minute or higher. (Type an integer or a decimal. Do not round.)
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.
