Rewrite each algebraic expression with fewer terms

Mathematics
1 answer:
gizmo_the_mogwai [7]3 years ago
6 0

1) solving 9.5(a + 4)-a we get 8.5a+38

2) Solving 8 + h- 2\times 5 we get -2+h

Step-by-step explanation:

Rewrite each algebraic expression with fewer terms

1) 9.5(a + 4)-a

Solving:

Multiplying 9.5 with terms inside the bracket

9.5(a + 4)-a\\=9.5a+38-a\\=8.5a+38

So, solving 9.5(a + 4)-a we get 8.5a+38

8 + h- 2\times 5

Solving:

8 + h- 2\times 5\\=8+h-10\\Combining\,\,like\,\,terms:\\=8-10+h\\=-2+h

So, Solving 8 + h- 2\times 5 we get -2+h

9c + 6 = 24 what does the variable c equal
NARA [144]

Answer:

c = 2

Step-by-step explanation:

Isolate the variable, c. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& roots)

Multiplications

Divisions

Additions

Subtractions

~

First, subtract 6 from both sides of the equation:

9c + 6 (-6) = 24 (-6)

9c = 24 - 6

9c = 18

Next, divide 9 from both sides of the equation:

(9c)/9 = (18)/9

c = 18/9

c = 2

c = 2 is your answer.

You estimated the average rental cost of a 2 bedroom apartment in Denton. A random sample of 16 apartments was taken. The sample
Zigmanuir [339]

Answer:

The new sample size required in order to have the same confidence 95% and reduce the margin of erro to $60 is:

n=28

Step-by-step explanation:

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

Assuming the X follows a normal distribution  

X \sim N(\mu, \sigma=160)  

And the distribution for \bar X is:

\bar X \sim N(\mu, \frac{160}{\sqrt{n}})  

We know that the margin of error for a confidence interval is given by:  

Me=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}   (1)  

The next step would be find the value of \z_{\alpha/2}, \alpha=1-0.95=0.05 and \alpha/2=0.025  

Using the normal standard table, excel or a calculator we see that:  

z_{\alpha/2}=\pm 1.96  

If we solve for n from formula (1) we got:  

\sqrt{n}=\frac{z_{\alpha/2} \sigma}{Me}  

n=(\frac{z_{\alpha/2} \sigma}{Me})^2  

And we have everything to replace into the formula:  

n=(\frac{1.96(160)}{78.4})^2 =16  

And this value agrees with the sample size given.

For the case of the problem we ar einterested on Me= $60, and we need to find the new sample size required to mantain the confidence level at 95%. We know that n is given by this formula:

n=(\frac{z_{\alpha/2} \sigma}{Me})^2  

And now we can replace the new value of Me and see what we got, like this:

n=(\frac{1.96*160}{60})^2 =27.32

And if we round up the answer we see that the value of n to ensure the margin of error required Me=\pm 60 $ is n=28.

None, because you need to make over 15,000 a year to be taxed. And with all that money for one year would not be taxed.
