Answer:

122.0627kg

Step-by-step explanation:

The standard deviation is the square root of the variance.

That means:

\sigma =  \sqrt{variance}

From the question, the standard deviation of the weights of the 10 random subjects is 11.0482kg

We substitute to get:

11.0482 =  \sqrt{variance}

We square both sides to get:

11.0482^{2} = variance

122.0627 = variance

Therefore the variance is 122.0627kg

What is the angle measure of an arc bounding sector with an area of 5pie square miles?
Snowcat [4.5K]

if the diameter is 20, the its radius must be half that or 10.

\textit{area of a sector of a circle}\\\\ A=\cfrac{\theta \pi r^2}{360}~~ \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ A=5\pi \\ r=10 \end{cases}\implies \begin{array}{llll} 5\pi =\cfrac{\theta \pi (10)^2}{360}\implies 5\pi =\cfrac{5\pi \theta }{18} \\\\\\ \cfrac{5\pi }{5\pi }=\cfrac{\theta }{18}\implies 1=\cfrac{\theta }{18}\implies 18=\theta \end{array}
