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)
4(x+7)=8x-20
4x+28=8x-20
28=4x-20
48=4x
x=12
The square root of 167 would be 12.922847. If you need it rounded to the nearest tenth it would be 12.9
If you need t rounded to the nearest hundredth, it would be 12.92.
Hope this helps :)
