Arduino is one of the largest selling items in Adafruit, which deals in circuit boards. The circuit board sells for $150 per unit and costs $100 to purchase. Based on the previous sales data, the average monthly demand is 1,000 boards with a standard deviation of 200 boards and it appears to follow a normal distribution. Adafruit uses 10% annual interest rate to estimate inventory holding costs and the fixed cost per replenishment is $200. Assume that the replenishment lead time is a month, unfulfilled demands are backordered, and backorder cost is $10/unit/year. Compute the optimal replenishment quantity and reorder point.

Ahorizontal force of 400.0 n is required to pull a 1760 n truck across the floor at a constant speed. find the coefficient of sliding friction.

Which statements identify what astronomers currently know and think will happen with our universe? check all that apply. the big bang produced dark energy, which accounts for some of the energy needed to expand the universe. the vastness of space may contain a type of matter known as "dark matter." the universe is currently shrinking at a rapid rate. the universe is currently expanding at an accelerating rate. the big bang theory explains all the energy and matter discovered by scientists.
