<span>First figure out how many people there are all together. So mrs and mr is 2 there three children so 2+3=5 so next round 179 to 200 and multiply 200x5. To do that you can use the mental math way witch would be to take the whole number out of 200 and make it 2. Then take the 5 in 200x5 and multiply 2x5. Then add the 2 zeros there were. And your estamated answer would be 1,000.
2+3=5
179=200
200x5
2x5=10
1,000
To figure out your real answer you will have to take 179 and multiply it by 5 so it will look like this:
 34
179
x
   5
895
Soto conculde the answer would be:

Estamated: $1,000

Exact: $895

Hope this helps!</span>

The remainder after dividing x4 + 3x3 − 8x2 + 5x − 9 by x + 5 is
BaLLatris [955]

Answer:

The remainder after dividing  x4 + 3x3 − 8x2 + 5x − 9 by x + 5 is 16

Step-by-step explanation:

We have to divide x4 + 3x3 − 8x2 + 5x − 9 by x+5

First of all we solve the first term of the dividend.

We have the divisor x+5

If we multiply it by x^3 than we get the first term of our dividend.

x^3(x+5) = x^4+5x^3

x4 + 3x3 − 8x2 + 5x − 9

x^4+5x^3

-      -

___________________

     -2x^3-8x^2+5x-9

Now we have the first term of dividend as -2x^3

Now we will multiply x+5 by -2x^2 to get the first term

-2x^2(x+5) =  -2x^3-10x^2

-2x^3-8x^2+5x-9

-2x^3-10x^2

+       +

______________

        2x^2+5x-9

Now the first term of the dividend is 2x^2

So we will multiply x+5 by 2x

2x(x+5)= 2x^2+10x

 

2x^2+5x-9

2x^2+10x

-       -

_________

       -5x -9

Now the dividend we have is -5x-9

We will multiply x+5 by -5

-5(x+5) = -5x-25

-5x -9

-5x-25

+    +

______

      16

Thus the remainder after dividing  x4 + 3x3 − 8x2 + 5x − 9 by x + 5 is 16....

Suppose that the researchers wanted to estimate the mean reaction time to within 6 msec with 95% confidence. Using the sample st
Lisa [10]

Answer:

a) The 95% confidence interval would be given by (509.592;550.308)  

b) n=523 rounded up to the nearest integer  

Step-by-step explanation:

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".  

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".  

\bar X=530 represent the sample mean for the sample  

\mu population mean

s=70 represent the sample standard deviation  

n=48 represent the sample size (variable of interest)  

Confidence =95% or 0.995

Part a

The confidence interval for the mean is given by the following formula:  

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

The degrees of freedom are df=n-1=48-1=47

Since the Confidence is 0.95 or 95%, the value of \alpha=0.05 and \alpha/2 =0.025, and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.025,47)".And we see that z_{\alpha/2}=2.01  

Now we have everything in order to replace into formula (1):  

530-2.01\frac{70}{\sqrt{48}}=509.692  

530+2.01\frac{70}{\sqrt{48}}=550.308  

So on this case the 95% confidence interval would be given by (509.592;550.308)  

Part b

The margin of error is given by this formula:  

ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}} (a)  

Assuming that \hat \sigma =s

And on this case we have that ME =6msec, and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

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

The critical value for 95% of confidence interval is provided, z_{\alpha/2}=1.96, replacing into formula (b) we got:  

n=(\frac{1.96(70)}{6})^2 =522.88 \approx 523  

So the answer for this case would be n=523 rounded up to the nearest integer
