You could model a strait road by using a segment addition postulate. For instance, if you are between point A and B you could calculate how much future you need to go by subtracting the length of the road by the distance you have traveled. Also, segment addition postulate can be used with City Water Lines or Sewer Lines. They can be used to calculate how much pipe is damaged and needs to be replaced.

yulyashka [42]

Answer:

Range = 2460 dollars, Variance = 516414.6 $dollars^2$ , Standard deviation = 718.6199 dollars . There are two outliers and they are likely to have much of an effect on the measures of variation.

Step-by-step explanation:

The smallest value in the sample data is min = 50 dollars and the largest value is max = 2500 dollars, therefore, the range is Range = max - min = 2500 - 40 = 2460 dollars. On the other hand, the formula to compute the sample variance is $S^2 = \frac{1}{n-1}\sum_{i=1}^{n} (x_{i}-\bar{x})^2$ where $\bar{x}$ is the sample mean, n is the sample size and the $x_{i}$ are the sample values. In this case the sample variance is $s^2$ = 516414.6 $dollars^2$ , the sample standard deviation is defined as the squared root of the sample variance, so, the sample standard deviation is s = 718.6199 dollars. There are two outliers because 1750 dollars and 2500 dollars are very different compared to the other values, these two numbers are very large and they are likely to have much of an effect on the measures of variation because these measures are sensible to outliers, they are no robust measures.
