Low risk suggested by the Greek proverb ——A bird in hand is worth two in the bush As the saying goes “A bird in the hand is worth two in the bush”‚ which is popularly applied to variety of daily life‚ because it warns us about the effects of greed‚ we can conclude from it that risk control can be an important element of investment.

Days-to-Repair When determining the number of days needed to repair a copier‚ it is best to assume that the number of days is random. It is best to generate this random‚ which is illustrated on the excel spreadsheet as r2. R2 will be numbers between 0 and 1. To determine this value a random number will be generated in excel. The number of days needed to repair the copier will be determined based on the cumulative outline below: 0.00 > r2 < 0.20‚ then it will take 1 day; 0.20 >

MBA 570 Homework Questions Chapter 1 and 2 Chapter 1 (1-20) Mysti Farris (See problem 1-19) is considering raising the selling price of each cue to $50 instead of $40. If this is done while the costs remain the same‚ what would the new breakeven point be? What would the total revenue be at this breakeven point? (Given in problem 1-19: fc of 2400 and vc of 25) (1-21) Mysi Farris (see problem 1-19) believes that there is a high probability that 120 pool cues can be sold if the selling price

appropriate to be used. Mean (Arithmetic) The mean (or average) is the most popular and well known measure of central tendency. It can be used with both discrete and continuous data‚ although its use is most often with continuous data (see our Types of Variable guide for data types). The mean is equal to the sum of all the values in the data set divided by the number of values in the data set. So‚ if we have n values in a data set and they have values x1‚ x2‚ ...‚ xn‚ the sample mean‚ usually denoted by (pronounced
