The answer is 1.27777778 (:
The answer is 6/21 is not in its simplest form as you can still divide them both by 3
She expects to receive about $5.00 because the total cost of the items is $12.13 so if you subtract how much money she brought and how much money she spent, ($17-$12.13) it would equal $4.87 which would round up to $5.00
Answer:
Step-by-step explanation:
Given that transitor has a 2% defective rate, need to calculate the probability that the 10th transistor produced is the first with a defect.
The probability function is p(x=k) = (1-p)^(n-1) * p
p = (1-defective rate)^(n-1) * defective rate; n=10
p = (1-0.02)^9 * 0.02 = 0.98^9 * 0.02 = 0.01666
Area = 10(pi)(16) = 160pi cubic feet
160pi = 502.56
502.56/8 = 63 minutes
