If u tell me what operation<span> is in between both the x's, then i can solve it for you</span>
Answer:
0.4546
Step-by-step explanation:
nCr = n!/(n-r)!r!
Number of ways of selecting the four defective voltage regulators from 12 = 12C4 = 12!/(12-4)!4! = 12!/8!4! = (12 *11*10*9)/(4*3*2*1)
12C4 = 495 ways
Number of ways of selecting 2 defectives from line 1 = 6C2 * 6C2
6C2 = 6!/(6-2)!2! = 6!/4!2! = (6*5)/(2*1) = 15
6C2 * 6C2 = 15*15 = 225 ways
Probability = Number of possible outcomes/ Number of total outcomes
Probability that exactly 2 of the defective regulators came from line 1 = 225/40.95 = 0.4546
Answer:
15lb
Step-by-step explanation:
1lb=453.59
Percentages and fractions so if you had to write 45 as a percentage it would be 45% and if you had to write it as a fraction it would be 45/100. In this case, you have 53.02 so as a percentage it would be 53.02% and as a fraction it would be 53/100. Hope this helps!!
Answer: 87.95
Step-by-step explanation: 10.3% of 853.93
10.3%= 0.103
So you would do 0.103 times 853.93=87.95479 round that to 2 Dp. You get 87.95
