Answer:
9 sqrt 3 in^2
Step-by-step explanation:
Assuming this is a equilateral triangle
find height
sin 60 = height/6
6 sqrt (3)/2 = height
3 sqrt 3 = height
area = 1/2 base * height
= 1/2 * 6 * 3 sqrt 3
= 9 sqrt 3 in^2
Answer:
E(x) = 1.43 (Approx)
Step-by-step explanation:
Given:
Total number of camera = 7
Defective camera = 5
Sample selected = 2
Computation:
when x = 0
P(x=0) = 2/7 × 1/6 = 2/42
P(x=1) = [2/7 × 5/6] + [5/7 × 2/6] = 20/42
P(x=2) = 5/7 × 4/6 = 20/42
So,
E(x) = [0×2/42] + [1×20/42] + [2×20/42]
E(x) = 1.43 (Approx)
