The arc length of AB is 8 m (app.)
Explanation:
Given that the radius of the circle is 8 m.
The central angle is 60°
We need to determine the arc length of AB
The arc length of AB can be determined using the formula,
Substituting central angle = 60° and circumference = 2πr in the above formula, we get,
Simplifying the terms, we get,
Dividing, we get,
Hence, the arc length is approximately equal to 8.
Therefore, the arc length of AB is 8 m
The <em>correct answer</em> is:
P(x) = 13x² – 10x + 350; 1,102 fish
Explanation:
I plotted this data in a graphing calculator. The screenshot is attached. You can see the curve of the parabola in the graph. I then ran the quadratic regression; again, the screenshot is attached. It lists the values of a, b and c for the equation y = ax²+bx+c.
P(
successes in 
trials) = ⁿ
×![[P(Success)^{r}]](https://tex.z-dn.net/?f=%20%5BP%28Success%29%5E%7Br%7D%5D%20)
×![[P(failure)]^{n-r}](https://tex.z-dn.net/?f=%20%5BP%28failure%29%5D%5E%7Bn-r%7D%20)
We have
Substitute these values into the formula, we have
P( 2 success in 8 trials) = ⁸C₂ × (0.15)² × (0.85)⁶
P( 2 success in 8 trials) = 0.2376.... ≈ 0.24 = 24%
