2.76 g
Step-by-step explanation:
The formula to find the standard deviation:-
The given data values : 560 g, 562 g, 556 g, 558 g, 560 g, 556 g, 559 g, 561 g, 565 g, 563 g.
Then,![\overline{x}=\dfrac{\sum_{i=1}^{10} x_i}{n}\\\\\Rightarrow\ \overline{x}=\dfrac{560+562+556+558+560+556+559+561+565+563}{10}\\\\\Rightarrow\ \overline{x}=\dfrac{5600}{10}=560](/tpl/images/0223/8229/a88e1.png)
Now,![\sum_{i=1}^{10}(x_i-\overline{x})^2=0^2+2^2+(-4)^2+(-2)^2+0^2+(-4)^2+(-1)^2+1^2+5^2+3^2\\\\\Rightarrow\ \sum_{i=1}^{10}(x_i-\overline{x})^2=76](/tpl/images/0223/8229/a70b1.png)
Then,![\sigma=\sqrt{\dfrac{76}{10}}=\sqrt{7.6}=2.76](/tpl/images/0223/8229/beeeb.png)
Hence, the standard deviation of his measurements = 2.76 g

Step-by-step explanation:
Data provided in the question
The radius of a wheel = 30 feet
Number of cars attached = 30 cars
Based on the above information
The computation is shown below:
The center angle is
The arc length is
= 1 feet
And, the area of a sector between two cars is
=![94.28\ ft^2](/tpl/images/0689/6637/25d72.png)
We simply do the above calculations so that each item could be find out
