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

e-lub [12.9K]

Answer:

The line's most probable length is 69.4012 meters.

The standard deviation is 0.0032 meters.

Step-by-step explanation:

We are given the following in the question:

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 $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

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

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

The line's most probable length is 69.4012 meters.

Sum of squares of differences = 0.0001016

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

The standard deviation is 0.0032 meters.

Hey is this correct?????

uranmaximum [27]

Answer:

y=2x-5

y=1/2x-2

2x-5=1/2x-2

3/2x-5=-2

3/2x=3

x=2

y=2(2)-5

y=4-5

y=-1

So, the answer is (2, -1)

Yep, you're correct.

Let me know if this helps!
