A)
x=sales
4/100 x + 400≥460
b)
Solve the inequation:
4/100 x+400≥460
lest common multiple= 100
4x+40000≥46000
4x≥46000-40000
4x≥6000
x≥6000/4
x≥1500
answer: the minimun amount tha se will needs to sell is $1500.

Answer:
99.9973 %
Step-by-step explanation:
This is a binomial probability distribution.
Since the probability of satisfactory welds = 97% = 0.97 and the probability of defective welds = 3% = 0.03.
Since there are 3 welds and we require at least one being defective, our binomial probability is
P(x ≥ 1) = 1 - P(x ≤ 0) = 1 - P(0) = 1 - ³C₀(0.03)³(0.97)⁰ = 1 - 1 × 0.000027 × 1 = 1 - 0.000027 = 0.999973 × 100% = 99.9973%
