Answer:

<h2>"Factor 4 out of the variable terms".</h2>

Step-by-step explanation:

The given equation is

4x^{2} +16x+3=0

Now, according to the problem, Maya is solving by completing the square.

The first step she needs to do is to factor 4 out of the variable terms,

4(x^{2} +4x)+3=0

Then, we move the constant to the other side

4(x^{2} +4x)=-3

Now, we divide the linear term by 2, and find its square power

x^{2} +4x+(\frac{4}{2} )^{2} =-\frac{3}{4} +4\\x^{2} +4x+4=\frac{16-3}{4} \\x^{2} +4x+4=\frac{13}{4}

Then, we factor the perfect square trinomial

(x+2)^{2}=\frac{13}{4}\\

Now, we solve for x

x=\sqrt{\frac{13}{4} } -2

Remember, a square root always has two solutions

x_{1}= +\frac{\sqrt{13} }{2}  -2\\x_{1}= -\frac{\sqrt{13} }{2} -2

Therefore, the first step Maya should take is "Factor 4 out of the variable terms".

In a random sample of fivefive microwave​ ovens, the mean repair cost was ​$75.0075.00 and the standard deviation was ​$13.0013.
Radda [10]
<h2>Answer with explanation:</h2>

As per given , we have

Sample size : n= 5

Degree pf freedom = : df= 5-1=4

\mu=\$75.00

\sigma=\$13.00

Significance level for 90% confidence = \alpha=1-0.90=0.1

Using t-value table , t-critical value for 90% confidence:

t_{\alpha/2, df}=t_{0.05, 4}=2.132.

Margin of error of \mu: E=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\(2.132)\dfrac{13}{\sqrt{5}}=12.3949720129\approx12.39

Interpretation : The repair cost will be within $12.39 of the real population mean value \mu 90% of the time.

Just replace x with whatever , and see if it works. If it works then it is a solution; otherwise it's not.

1^2 is not 2
(1/2)^2 isn't 2 either...
and so on
