(13-10)/10 × 100% = 3/10 × 100% = 30%
Answer: 0.3399
Step-by-step explanation:
The binomial probability distribution formula to find the probability of getting success in x trial:-
, 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 : 
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](https://tex.z-dn.net/?f=P%28x%3D0%29%3D%5E%7B2%7DC_0%280.417%29%5E0%281-0.417%29%5E%7B2%7D%5C%5C%5C%5C%3D%281%29%281%29%280.583%29%5E%7B2%7D%5C%20%5C%20%5C%20%5B%5Ctext%7B%20Since%7D%5EnC_0%3D1%5D%5C%5C%5C%5C%3D0.339889%5Capprox0.3399)
Hence, the probability that neither of them was defective = 0.3399
A minute is 6 times as long as 10 seconds, so we expect Karl will ride 6 times as far.
Karl rides 720 ft in 1 minute.
Answer:
A. an = -3 + 4(n - 1)
Step-by-step explanation:
The sequence given follows an arithmetic progression. This means the following term can be gotten by simply adding a factor to the previous term (or even the first term).
They are represented by the equation:
y(n) = a + r(n - 1)
Where y(n) is the nth term
a = first term
r = factor
Let us compare this with the sequence given:
The first term, a, is -3
We can get the factor, r, by using the second term, which is 1. This means n = 2.
=> 1 = -3 + r (2 - 1)
1 = -3 + r
=> r = 1 + 3 = 4
Therefore, putting a = -3 and r = 4, the sequence can be written as:
y(n) = -3 + 4(n - 1)
