Mark bought a CD for $500 that earns 3.9% APR and is compounded
quarterly. The CD matures in 3 years. How much will this CD be worth at
maturity?

Solve for x by completing the square. 2x^2-4x+7=0

Polynomial that can be factored as (3x-4)(3x+4)

Assume that the weights of quarters are normally distributed with a mean of 5.67 g and a standard deviation 0.070 g. a vending machine will only accept coins weighing between 5.48 g and 5.82 g. what percentage of legal quarters will be rejected? round your answer to two decimal places.
