The correct simplification of 8x2(5x 2x2 − 3) is $16x^{4} +40x^{3} -24x^{2}$

<h3>What do you mean by simplification?</h3>

Simplifying procedures is one way to achieve uniformity in work efforts, expenses, and time. It reduces diversity and variety that is pointless, harmful, or unnecessary.
Making anything simpler is the act or process of simplification. Everyone is in favor of streamlining court procedures.
Certain "solving" issues are connected to "simplification" issues. Parentheses and even nested grouping symbols can be found in some equations, just like in some expressions. Whether we're working with equations (so we're also solving) or expressions (and only simplifying), the simplification procedure is the same in both cases.

The correct simplification of 8x2(5x 2x2 − 3).

$8x^{2} (5x+2x^{2+1} -3)=8*2x^{2+2} -8*3x^{2}$

$=40x^{3} +16x^{4} -24x^{2}$

Rearranging the above expression in descending order of power, we get: $16x^{4} +40x^{3} -24x^{2}$

The correct simplification of 8x2(5x 2x2 − 3) is $16x^{4} +40x^{3} -24x^{2}$

Answer:

Step-by-step explanation:

observe

$2x^2-5x+5=0\\x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\\=\frac{5\pm \sqrt{(-5)^2-4(2)(5)}}{2(2)}\\=\frac{5\pm \sqrt{-15}}{4}\\=\frac{5\pm i\sqrt{15}}{4}$

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.
