Which are steps that could be used to solve 0 = 9(x2 6x) – 18 by completing the square? Check all that apply. 18 81 = 9(x2 6x 9)
Marina CMI [18]

Answer:

18 + 81 = 9(x² + 6x + 9) 11 = (x + 3)²

Explanation:

because  This is the value that completes the square. However, since the entire square is multiplied by 9, this value must be multiplied by 9 before we can add it across the equals:

18 + 9 (9) = 9 (x² + 6x + 9)

18 + 81 = 9 (x² + 6x + 9)

99 = 9 (x² + 6x + 9)

Dividing both sides by 9, we have:

11 = x² + 6x + 9

11 = (x + 3) ²

Which reaction will most likely take place based on the activity series? li > k > ba > ca > na > mn > zn >
Ivenika [448]

The only reaction that will most likely take place based on the activity series is; C: Ba + Na₂CO₃

<h3>Activity Series</h3>

From the activity series given, we can say that during a displacement reaction, the more reactive metal will always displace the lesser reactive metal from a compound.

Let us look at each of the given options;

A) Ag + FeCl₃

From the activity series, Silver(Ag) is less reactive than Iron(Fe) and as such Silver cannot displace iron from its' compound.

B) Zn + CaO

Zinc (Zn) is a less reactive metal than Calcium (Ca), so it cannot cannot displace Calcium from its' compound.

C) Ba + Na₂CO₃

Barium (Ba) is a more reactive metal than Sodium (Na), and therefore Barium will displace sodium from its compound in a displacement reaction.

D) Cr + KNO₃

Chromium (Cr) is a lesser reactive metal than Potassium (K), and it therefore cannot displace Potassium from its compound.

Complete question is;

Which reaction will most likely take place based on the activity series? Li > K Ba > CaNa > Mn > Zn > Cr> Fe> Cd Ni > H > Sb > Cu > Ag > Pd > Hg > Pt

A. Ag + FeCl₃

B. Zn + CaO

C. Ba + Na₂CO₃

D. Cr + KNO₃

Suppose that the annual federal deficit is $350 billion. Gross domestic product 'gdp', a measure of the size of the economy is $
larisa86 [58]

Based on the information the ratio between the deficit and gdp as a percentage is 2.41%.

<h3>Ratio between the deficit and gdp:</h3>

Using this formula

Ratio between the deficit and gdp=Annual federal deficit/Gross domestic product×100

Where:

Annual federal deficit=$350 billion

Gross domestic product=$14,500 billion

Let plug in the formula

Ratio between the deficit and gdp=$350 billion/$14,500 billion×100

Ratio between the deficit and gdp=2.41%

Inconclusion the ratio between the deficit and gdp as a percentage is 2.41%.

A survey showed that 34 ​% of human resource professionals are at companies that rejected job candidates because of information
Svetllana [295]

Using the binomial distribution, it is found that since 16 is more than 2.5 standard deviations above the mean, it is a unusually high number.

<h3>What is the binomial probability distribution?</h3>

It is the probability of <u>exactly x successes on n repeated trials, with p probability</u> of a success on each trial.

The expected value of the binomial distribution is:

E(X) = np

The standard deviation of the binomial distribution is:

\sqrt{V(X)} = \sqrt{np(1-p)}

A measure is considered to be unusually high if it is more than 2.5 standard deviations above the mean.

In this problem, we hav ehtat:

  • 34% of companies reject candidates because of information found on their social media, hence p = 0.34.
  • 27 human resource professionals are randomly​ selected, hence n = 27.

Then, we find the threshold for unusually high values as follows:

E(X) = np = 27 x 0.34 = 9.18

\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{27(0.34)(0.66)} = 2.46

T = 9.18 + 2 x 2.46 = 14.1.

Since 16 is more than 2.5 standard deviations above the mean, it is a unusually high number.
