Answer: Option A

$x=\frac{3+i}{2}$ or $x=\frac{3-i}{2}$

Step-by-step explanation:

Use the quadratic formula to find the zeros of the function.

For a function of the form

$ax ^ 2 + bx + c = 0$

The quadratic formula is:

$x=\frac{-b\±\sqrt{b^2-4ac}}{2a}$

In this case the function is:

$2x^2-6x+5=0$

So

$a=2\\b=-6\\c=5$

Then using the quadratic formula we have that:

$x=\frac{-(-6)\±\sqrt{(-6)^2-4(2)(5)}}{2(2)}$

$x=\frac{6\±\sqrt{36-40}}{4}$

$x=\frac{6\±\sqrt{-4}}{4}$

Remember that $\sqrt{-1}=i$

$x=\frac{6\±\sqrt{4}*\sqrt{-1}}{4}$

$x=\frac{6\±\sqrt{4}i}{4}$

$x=\frac{6\±2i}{4}$

$x=\frac{3\±i}{2}$

$x=\frac{3+i}{2}$ or $x=\frac{3-i}{2}$

In a certain computer, the probability of a memory failure is 0.01, while the probability of a hard disk failure is 0.02. If the

Answer:

We need to remember that we have independent events when a given event is not affected by previous events, and we can verify if two events are independnet with the following equation:

$P(A \cap B) = P(A) *P(B)$

For this case we have that:

$P(A) *P(B) = 0.01*0.02= 0.0002$

And we see that $0.0002 \neq P(A \cap B)$

So then we can conclude that the two events given are not independent and have a relationship or dependence.

Step-by-step explanation:

For this case we can define the following events:

A= In a certain computer a memory failure

B= In a certain computer a hard disk failure

We have the probability for the two events given on this case:

$P(A) = 0.01 , P(B) = 0.02$

We also know the probability that the memory and the hard drive fail simultaneously given by:

$P(A \cap B) = 0.0014$

And we want to check if the two events are independent.

We need to remember that we have independent events when a given event is not affected by previous events, and we can verify if two events are independnet with the following equation:

$P(A \cap B) = P(A) *P(B)$

For this case we have that:

$P(A) *P(B) = 0.01*0.02= 0.0002$

And we see that $0.0002 \neq P(A \cap B)$

So then we can conclude that the two events given are not independent and have a relationship or dependence.

A donation center had filled up 44 small bins with canned food with each bin containing 24 cans. They plan to send the cans out

Valentin [98]

Each food bank would receive 264 cans.

44 Bins with 24 cans. 44•24= 1,056

n= (44•24) / 4
n= 1,056 / 4
n= 264 cans per food bank
