Eqyivalent expresion to 3√m^2n^5
Irina18 [472]
The first step to solving this expression is to factor out the perfect cube
\sqrt[3]{m^{2}  n^{3} X n^{2}   }
The root of a product is equal to the product of the roots of each factor. This will make the expression look like the following:
\sqrt[3]{ n^{3} } \sqrt[3]{ m^{2} n^{2}  }
Finally,, reduce the index of the radical and exponent with 3
n\sqrt[3]{ m^{2} n^{2}  }
This means that the correct answer to your question is n\sqrt[3]{ m^{2} n^{2} } .
Let me know if you have any further questions

The manager of a grocery store has taken a random sample of 100 customers. The average length of time it took these 100 customer
AlladinOne [14]

Answer:

4-2.326\frac{1}{\sqrt{100}}=3.767    

4+2.326\frac{1}{\sqrt{100}}=4.233    

So on this case the 98% confidence interval would be given by (3.767;4.233)

Step-by-step explanation:

Previous concepts

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=4 represent the sample mean

\mu population mean (variable of interest)

\sigma=1 represent the population standard deviation

n=100 represent the sample size  

Solution to the problem

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

\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}}   (1)

Since the Confidence is 0.98 or 98%, the value of \alpha=0.02 and \alpha/2 =0.01, and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-NORM.INV(0.01,0,1)".And we see that z_{\alpha/2}=2.326

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

4-2.326\frac{1}{\sqrt{100}}=3.767    

4+2.326\frac{1}{\sqrt{100}}=4.233    

So on this case the 98% confidence interval would be given by (3.767;4.233)

Acute angle DOG with a measure of 45 degrees
Vlad1618 [11]
So make and angle with the measure of 45 degrees. And then label it DOG. It doesn't matter where you start labeling as long as O is your midpoint. :)

zepelin [54]

Answer:

The 6 in 4,786.53, is 6 times greater than the 6 in 3,821.69.

Step-by-step explanation:

The value of 6 in 4,786.53, is in the ones. 6

The value of 6 in 3,821.69, is in the tenths. 0.6

6/0.6 = 10

The 6 in 4,786.53, is 6 times greater than the 6 in 3,821.69.

Hope that helps!
