Find a quadratic equation with integer coefficient ,if one of the roots is 7-root3
solmaris [256]
One of the roots of a quadratic equation is 7 - √3.

Because rational roots occur in conjugate pairs, the other root is 7 + √3.
The quadratic equation is
(x -(7-√3))(x - (7+√3))
= x² - (7+√3)x  - (7-√3)x + (49-3)
= x² - 7x - (√3)x - 7x + (√3)x + 46
= x² - 14x + 46

Answer: x² - 14x + 46

The high price of medicines is a source of major expense for those seniors in the United States who have to pay for these medici
Ilia_Sergeevich [38]

Answer:

4600-1.646\frac{800}{\sqrt{1800}}=4568.96    

4600+1.646\frac{800}{\sqrt{1800}}=4631.04    

We are confident at 90% that the true mean for the amount spent on medicines is between (4568.96 and 4631.04)

Step-by-step explanation:

Information given

\bar X=4600 represent the sample mean for the amount spent on medicines

\mu population mean

s=800 represent the sample standard deviation

n=1800 represent the sample size  

Solution

The confidence interval for the true population mean is given by:

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

We can calculate the degrees of freedom with:

df=n-1=1800-1=1799

We know that the Confidence level is 0.90 or 90%, the value of significance is \alpha=0.1 and \alpha/2 =0.05, and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.05,1799)".And we see that t_{\alpha/2}=1.646

Replcing in the formula for the confidence interval we got:

4600-1.646\frac{800}{\sqrt{1800}}=4568.96    

4600+1.646\frac{800}{\sqrt{1800}}=4631.04    

We are confident at 90% that the true mean for the amount spent on medicines is between (4568.96 and 4631.04)
