Jorgensens, an Electronics

pshichka [43]

Answer: 0.3399

Step-by-step explanation:

The binomial probability distribution formula to find the probability of getting success in x trial:-

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where n is the number of trials and p is the probability of getting success in each trial.

Given : Jorgensens received a shipment of 12 DVD Players. Shortly after arrival the manufacturer called to say that that he had accidentally shipped five defective units with the shipment.

i.e. The proportion of the defective units : $p=\dfrac{5}{12}\approx0.417$

Also, Mr. Jorgensen pulled ten of the units and tested two of them.

For n=2, the probability that neither of them was defective:-

$P(x=0)=^{2}C_0(0.417)^0(1-0.417)^{2}\\\\=(1)(1)(0.583)^{2}\ \ \ [\text{ Since}^nC_0=1]\\\\=0.339889\approx0.3399$

Hence, the probability that neither of them was defective = 0.3399

a square foot of metal is 49 feet2 what is the length of each side of the sheet metal. what is the perimeter

riadik2000 [5.3K]

Take the square root of 49 which is 7 (the length of each side), then multiply 7 by the number of sides which is 4, so you would get 28 as the perimeter. Hope this helps :)
