Answer:
a) 0.5514
b) 0.0058
Step-by-step explanation:
Data provided in the question:
Probability that the the selected person is righthanded, P(R) = 0.82
Therefore,
Probability that the the selected person is not righthanded, P(R') = 1 - 0.82
= 0.18
Now,
a. They are all right-handed
P (They are all right-handed) = P(R) × P(R) × P(R)
= 0.82 × 0.82 × 0.82
= 0.5514
b) None of them is right-handed
P (None of them is right-handed) = P(R') × P(R') × P(R')
= 0.18 × 0.18 × 0.18
= 0.0058

Answer:
An apothem is a line drawn from the centerpoint of the polygon to one side of the polygon. There is a formula for area in terms of apothem:
A = (1/2)*(Perimeter)*(Apothem)
The perimeter of the regular polygon is just the length of one side multiplied with the number of sides. Since a polygon with 9 sides,
P = 9(15) = 135in
A = 1/2 ×135 × 12
A = 810 square inches ans
D- (-2,3) :)
