2 pts You are trying to collect some data about the cost of off-campus rent for Texas State students living in San Marcos. The registrar gives you a list of emails for all students at the university: you assign a number to each email and use a random number generator to select a sample of 100 students to contact. The average rent for this sample is $750. Shortly after you have finished collecting your data, the registrar contacts you again with some useful information: a study about rent cost for all students was recently completed. The average cost for all students at the university is actually $650 with a standard deviation of $50. Assuming you followed all of the steps correctly for random sampling, what is the cause of the difference you see between your sample mean ($650) and the actual population mean ($750)?​

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

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2

Ive seen this before! the answer is b
