Pulse rates of women are normally distributed with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per minute. Answer the following questions. (x- H). What are the values of the mean and standard deviation after converting all pulse rates of women to z scores using z= The original pulse rates are measure with units of "beats per minute". What are the units of the corresponding z scores? Choose the correct choice below. O A. The z scores are measured with units of "beats per minute." O B. The z scores are measured with units of "beats." Oc. The z scores are measured with units of "minutes per beat." O D. The z scores are numbers without units of measurement.
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.
