Over the first five years of owning her car, gina drove about 12,200 miles the first year, 16,211 miles the second year, 12,050 the third year, 11,350 the fourth year, and 13,325 the fifth year. a. find the mean, median, and mode of this data. b. explain which measure of central tendency will best predict how many miles gina will drive in the sixth year. mean = 13,027; median = 12,200; no mode; the mean is the best choice because it is representative of the entire data set. mean = 13,027; median = 12,200; no mode; the median is the best choice because it is not skewed by the high outlier. mean = 13,027; median = 12,200; mode = 4,861; the median is the best choice because it is not skewed by the high outlier. mean = 12,200; median = 13,027; no mode; the mean is the best choice because it is representative of the entire data set. i think its d. but im not sure

I think it is a or b for answer

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
