Step-by-step explanation:
Use arc length:
s = rθ
where r is the radius and θ is the angle in radians.
a) First, convert the angle to radians (1 degree = 60 minutes).
77 ⁵⁰/₆₀° × (π radian / 180°) = 1.358 radians
s = rθ
s = (9.67 in) (1.358 rad)
s = 13.1 in
b) s = rθ
4 in = (9.67 in) θ
θ = 0.414 radians
θ = 23.7°
θ = 23° 42'
There are two real roots (5 and -5) and 4 imaginary roots
When you plot the numbers on a graph or draw a histogram using them, you find the distribution shapes are
Lake A: ∩
Lake B: ∪
Lake C: ∩
Lake D: ∩
Apparently the weights of fish in Lake B have a U-shaped distribution.
