These two maps show the same area at two different scales. Colombus is not on Map A. Scale on Map A, 1 cm = 40 mi. Map B does no

t have a scale written on it. Riverside and Gladville are 6.8 cm apart on Map A. Riverside and Gladville are 3.4 cm apart on Map B. Gladville and Columbus are 1.8 cm apart on Map B. Determine the straight line distance, in miles, from Gladville to Columbus. ​

Leslie's mistake lies in using a dilation, which either scales an object down or up. This transformation cannot be applied because congruent segments must maintain equal length; only rigid transformations like translations, reflections, and rotations are permissible. Thus, dilation is not considered a rigid transformation.

A distance AB is observed repeatedly using the same equipment and procedures, and the results, in meters, are listed below:69.40
Zina [12379]

Answer:

The most likely length of the line is 69.4012 meters.

The calculated standard deviation amounts to 0.0032 meters.

Step-by-step explanation:

In the problem, the following values are provided:

69.401, 69.400, 69.402, 69.396, 69.406, 69.401, 69.396, 69.401, 69.405, 69.404      

Formula:

\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n}}  

where x_i represent data points, \bar{x} is the average, and n indicates the count of observations.  

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle\frac{694.012}{10} = 69.4012

The most likely length of the line is 69.4012 meters.

Sum of squares of differences = 0.0001016

\sigma = \sqrt{\dfrac{0.0001016}{10}} = 0.0032

The calculated standard deviation amounts to 0.0032 meters.
