Answer:
2³ · 7
Step-by-step explanation:
Find the area of the triangle, the rectangle and the semi circle.
Area of the triangle = (bh)/2 = (12*5)/2 = 30
Area of The rectangle = L*W = 40 * 12 = 480
Area of the semi circle = (πr²)/2 = (3.14*6²)/2 = 56.52
Now add them all together = 30 + 480 + 56.52 = 566.52 ft²
Hope this helps :)

Answer:
0.071%
Step-by-step explanation:
The probability of success is constant, and each dolphin is independent, so this is an example of a binomial distribution.
P = nCr p^r q^(n-r)
where P is the probability of r number of successes out of n number of trials, p is the probability of success, and q is probability of failure (1-p).
Given: n = 8, r = 4, p = 0.94, q = 0.06:
P = ₈C₄ (0.94)⁴ (0.06)⁸⁻⁴
P = 70 (0.94)⁴ (0.06)⁴
P ≈ 0.071%
