At the candle factory, 10 out of 100 produced candles in the sample are defective. Find a point estimate of the probability that a fault free candle is produced.

p=0.9

Step-by-step explanation:

Total Sample of Candles =100

Number of defective Candles = 10

Therefore, the number of fault-free candles =100-10=90

A point estimate of the probability that a fault-free candle is produced is:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

answer is b
