Answer:

R² =206/π ==>R² = 206/3.1459==> R² =65.5 ==> R=√65.5 ≈8 ft

The area of a circle = πR², where π=3.1459... & R = Radius

The area of our circle  ≈ 206 ft² = πR², Solve for R²:

R² =206/π ==>R² = 206/3.1459==> R² =65.5 ==> R=√65.5 ≈8 ft

In a circle of radius 60 inches, a central angle of 35° will intersect the circle forming an arc of length

\bf \textit{arc's length}\\\\
s=\cfrac{\theta \pi r}{180}~~
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad degrees\\
------\\
r=60\\
\theta =35
\end{cases}\implies s=\cfrac{(35)(\pi )(60)}{180}\implies s=\cfrac{35\pi }{3}

What is the difference between population parameters and estimates in a sample?
Anna35 [415]

Answer:

Using that sample, you calculate the corresponding sample characteristic, which is used to summarize information about the unknown population characteristic. The population characteristic of interest is called a parameter and the corresponding sample characteristic is the sample statistic or parameter estimate.

Step-by-step explanation:

If you collect a sample and calculate the mean and standard deviation, these are sample statistics.

20 Points - A mathematical model estimates sales (in thousands of dollars) as a function of time t (in years) as S(t) = 5t/t+1,
adelina 88 [10]
The first choice is the correct answer. Note that for S(t) = 5t/(t+1):At t = 0, S = 0At t = 1, S = 5(1/2)At t = 2, S = 5(2/3)And as t increases, S approaches 5. (The pattern 1/2, 2/3, 3/4...gets closer and closer to 1).
