The medical records of infants delivered at the Kaiser Memorial Hospital show that the infants’ lengths at birth (in inches) are normally distributed with a mean of 21 and a standard deviation of 2.6. Find the probability that an infant selected at random from among those delivered at the hospital measures is more than 23inches.

Cherie measures and records the lengths and sizes of the same style of a sandal found at a shoe store. which equation can be used to determine the approximate shoe size, s, for a foot length of x inches? s = x – 2 s = 2x – 10 s = x + 6 s = 2x + 4

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e.g. 98.7654). x f(x) 0 1 2 3

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14
