Amachine packages bags of almonds. the weights of the bags are normally distributed with a mean of 14 ounces and a standard deviation of 1.2 ounces. enter the z-score of a bag of almonds that weighs 12.2 ounces.

Z = (x - μ)/σ

Fill in the given information and do the arithmetic.
z = (12.2 -14)/1.2 = -1.8/1.2

z = -1.5

Z= x - mean/SD so 12.2-14/1.2= -1.5

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
