9/81 is equivalent to which fraction? please explain

2 answers:

8 0

9/81 can be simplified into 1/9. You divide both the top and bottom part of the fraction by 9.
9/9=1 and 81/9=9 to get 1/9. but that's it's simplified version. equivalent fractions of it can be almost anything. like, 1/9 can equal 2/18, 3/27, or 4/36.

Answer:

9/81 is equivalent to 1/9.

Step-by-step explanation:

The easiest way to solve this is seeing if we can write 81 as a product os nines.

We have that $81 = 9^{2}$ . So we can simplify the following way:

$\frac{9}{81} = \frac{9}{9^{2}} = \frac{9}{9*9} = \frac{1}{9}$ .

This means that 9/81 is equivalent to 1/9.

Answer:

The 95 percent confidence interval for the population mean is between 14.736 tons and 16.864 tons.

Step-by-step explanation:

We have the population's standard deviation, so we can find the normal confidence interval.

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.95}{2} = 0.025$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.025 = 0.975$ , so $z = 1.96$

Now, find the margin of error M as such

$M = z*\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

$M = 1.96*\frac{3.8}{\sqrt{49}} = 1.064$

The lower end of the interval is the sample mean subtracted by M. So it is 15.8 - 1.064 = 14.736 tons

The upper end of the interval is the sample mean added to M. So it is 15.8 + 1.064 = 16.864 tons

The 95 percent confidence interval for the population mean is between 14.736 tons and 16.864 tons.

Stan is purchasing sub-flooring for a kitchen he is remodeling. The area of the floor is 180 ft' and

DiKsa [7]

Answer:

15 feet = Length

Step-by-step explanation:

The area of a rectangle is:

Area = Length x Width

The Area is given as 180 square feet (ft2) and the width is given as 12 feet. Let's plug those values into the Area formula to find the length:

Area = Length x Width

180 = Length x 12

Divide both sides of the equation by 12:

180/12 = Length

15 feet = Length
