1. Suppose, as is roughly true, the amount of money U. S. smokers spend on cigarettes each year is distributed normally with a mean (µ) of $1,250 and a standard deviation (σ) of $220.
(a) (5 pts.) What is the probability that a single randomly selected smoker in the U. S, spends more than $1,350

Scenario: susan wants to make 2 square flags to sell at a crafts fair. the fabric she wants to buy is 3 meters wide. she doesn't want any fabric left over. what's the least amount of fabric she should buy? question: which equation will susan solve her problem? note: let x represent the length of 1 side of the flag. options: 1) 2x^2 = 4x 2) 8 +2x = 2(4x) 3) 2 * 2 = 4 * 2 4) 4x^2 -2x = 0
