Answer:
Mean, E(x) = 0.17
Variance, V(x) = 0.12
Step-by-step explanation:
90% contains no defective bulbs, P(X=0) = 0.9
5% contain one defective bulbs, P(X=1) = 0.05
3% contain two defective bulbs, P(X=2) = 0.03
2% contain three defective bulbs, P(X=3) = 0.02
The mean for the number of defective bulbs:
Variance for the defective bulbs:
V(x) = 0.29 - 0.17
V(x) = 0.12
It should be $4 sorry if it is wrongbut i pretty sure that is he answer
86 × π = 86π
or
86 × 3.14 = 270.04
you can use both of them depends on what form the question is asking that ur answer be in
Answer:
k(3) = 18
Step-by-step explanation:
k(n) = 2n²
k(3) = 2 * (3)²
k(3) = 2 * 9
k(3) = 18
