Answer:

The answer is $5.70.

Step-by-step explanation:

By multiplying 95 by 0.06, you will get 5.7. If you divide 95 by 100 then multiplying it by 0.06, you can also get 5.7. This is because percents can be converted to decimals. 0.06 is the equivalent of 6%.

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)

If rhe discriminant of a quadratic equation is equal to -8 which statement describes the roots

Nastasia [14]

Answer:

Step-by-step explanation:

Given

$Discriminant = -8$

Required

Determine the type of roots

Represent Discriminant with D; such that

$D = -8$

D is calculated as thus

$D = b^2 - 4ac$

And it has the following sequence of results

When $D > 0;$ then the roots of the quadratic equation are real but not equal

When $D = 0;$ then the roots of the quadratic equation are real and equal

When $D < 0;$ then the roots of the quadratic equation are complex or imaginary

Given that $D = -8$ ; This means that $D < 0;$ and base on the above analysis, we can conclude that the roots of the quadratic equation are complex or imaginary

How can we find the measure of an exterior angle if we know the measurement of an interior angle

Alik [6]

Step-by-step explanation:

Put the interior angle equal to 180.

It would look something like this:

x+45=180

-45 -45

180-45= 135 so the exterior angle would be 135!
