Answer:
16.2 miles
Step-by-step explanation:
just add 6.4 and 9.8 you will get 16.2 miles
since the polygon has 8 chambers the angle of one chamber = 360/8 = 45°
so the angle WOP = 45°
now drawing a imaginary line which seperates the triangleWOP into half
so the angle of imaginary line is 45/2 = 22.5
sin(theta) = opp/hyp
since WP (opp) is unknown. take as x
sin(22.5) = x/44
0.383×4 = x
x = 1.532 (app) = 1.5 cm
perimeter = 1.5 × 8
= 12 cm
area of triangle WOP = 2×1/2 ×bh = bh
= 4×1.5
= 6 cm²
so the area of regular polygon = 8× area of a triangle
= 48 cm²
The number g is 7
24-10 = 14
14/2=6
Let X be a random variable representing the score of of student.
P(X ≥ 50) = 1 - P(X < 50) = 1 - P(z < (50 - 42)/8) = 1 - P(z < 1) = 1 - 0.84134 = 0.15866
