The answer is A. y=3(x-1)^2+1. You have to complete the square on the right side of the equation, then reorder the right side of the equation to match the vertex form of a parabola.

Suppose you just received a shipment of eleven televisions. Three of the televisions are defective. If two televisions are rando

salantis [7]

Answer: The probability that both televisions work : 0.5329

The probability at least one of the two televisions does not work : 0.4671

Step-by-step explanation:

Given : The total number of television : 11

The number of defective television : 3

The probability that the television is defective : $p=\dfrac{3}{11}\approx0.27$

Binomial distribution formula :-

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

If two televisions are randomly selected, then the probability that both televisions work:

$P(0)=^2C_0(0.27)^0(1-0.27)^{2-0}=(1)(0.73)^2=0.5329$

The probability at least one of the two televisions does not work :

$P(X\geq1)=1-P(0)=1-0.5329=0.4671$
