Polymer composite materials have gained popularity because they have high strength to weight ratios and are relatively easy and inexpensive to manufacture. however, their nondegradable nature has prompted development of environmentally friendly composites using natural materials. an article reported that for a sample of 10 specimens with 2% fiber content, the sample mean tensile strength (mpa) was 51.9 and the sample standard deviation was 1.2. suppose the true average strength for 0% fibers (pure cellulose) is known to be 48 mpa. does the data provide compelling evidence for concluding that true average strength for the wsf/cellulose composite exceeds this value? (use α = 0.05.)

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
