Answer quick will give branliest myrna wants to know about how many pairs of jeans middle school students own. she did not have time to ask all 257 middle school students, so she surveyed a random sample of 25 students. the results below display the number of pairs of jeans each surveyed student owns. 3, 4, 2, 1, 3, 1, 2, 4, 2, 3, 1, 2, 4, 2, 3, 2, 2, 6, 1, 1, 2, 4, 1, 1, 2 the mean of her data is 2.36 pairs of jeans. from the given data and the calculated mean, which inference could myrna make? 1. all middle school students own jeans. 2. the average middle school student owns around two pairs of jeans. 3. most seventh-grade students prefer cargo pants to jeans. 4. an average middle school student owns three or more jeans.

To be honest I don't know but for me personally I would pick the last one.

2. The average middle school student owns around two pairs of jeans.

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
