Acts of kindness On March 19‚ 1994‚ I experienced firsthand how one random act of kindness could touch my heart‚ ease my fears and leave me with a renewed faith in mankind. I was living in Billings‚ Montana and was moving back home to Kennewick‚ Washington with my six month old daughter. It was a 670 mile journey. I drove a little blue Ford Festiva and had it packed to the point where I didn’t think anything else could fit in it. It was a beautiful sunny morning when we left on our journey

is the chi-square distribution because the sum of the squares of independent normal random variables with mean zero and standard deviation one has a chi-square distribution. This section collects some basic properties of chi-square random variables‚ all of which are well known; see Hogg and Tanis [6]. A random variable X has a chi-square distribution with n degrees of freedom if it is a gamma random variable with parameters m = n/2 and = 2‚ i.e X ~ (n/2‚2). Therefore‚ its probability density

This model would be sold to retailers for $375. The variable cost of this unit is $225. The demand for the new Model LX4 is estimated to be 300 units per year. Sixty percent of these unit sales of the new model

able to determine whether a cost is fixed or variable is vital to the understanding of overhead loading and cost behavior. A fixed cost is unchanged with a change to the cost driver. (Horngren‚ Sutton‚ and Stratton p.46) Which means that a fixed cost does not rise with the change is production of your product. A good example of a fixed cost is rent. No matter how many widgets you make (within a relevant range) your rent will not increase. A variable cost‚ on the other hand‚ does change with the

example‚ the proportion of individuals in a random sample who support one of two political candidates fits this description. In this case‚ the statistic is the count X of voters who support the candidate divided by the total number of individuals in the group n. This provides an estimate of the parameter p‚ the proportion of individuals who support the candidate in the entire population. The binomial distribution describes the behavior of a count variable X if the following conditions apply: the number

distribution of a discrete random variable that has a large number of applications. Suppose a washing machine in a Laundromat breaks down an average of three times a month. We may want to find the probability of exactly two breakdowns during the next month. This is an example of a Poisson probability distribution problem. Each breakdown is called an occurrence in Poisson probability distribution terminology. The Poisson probability distribution is applied to experiments with random and independent occurrences

Variable costing and absorption costing are the two most commonly used methods of inventory costing for manufacturing companies. The inventory method of variable costing takes place when total direct and indirect variable manufacturing costs are included within inventoriable costs. Fixed manufacturing costs however‚ are considered costs of the period under variable costing. The next method of inventory costing‚ absorption costing‚ includes all variable manufacturing costs as well as fixed manufacturing
