The data set gives the heights of the workers at a body shop in centimeters.
{175, 163, 180, 172, 179, 178, 173, 168, 180, 176, 174, 183, 186, 184, 169}
which of the following is the best measure of the central tendency?
a. mean
b. mode
c. range
d. standard deviation
e. interquartile range

I think the correct answer from the choices listed above is option A. The mean is the best measure of the central tendency of the data set. Mean is generally considered the best measure of central tendency and the most frequently used one. Hope this answers the question.

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
