Which fraction equals a repeating decimal

bezimeni [28]

Here are some Examples: :)

$\frac{2}{9}$ is 0.2222222222 and so on

$\frac{4}{9}$ is 0.4444444444 and so on

$\frac{7}{9}$ is 0.777777777 and so on

So it could be anything like 9 or 6 as long is its like this $\frac{9}{4}$

Answer:

8 times

Step-by-step explanation:

<u>The volume of the prism:</u>

V = lwh

<u>If each of the dimensions is doubled, then the volume becomes:</u>

V₁ = 2l*2w*2h = 8lwh = 8V

The larger prism has 8 times greater volume

Find the variance of this probability distribution. Round to two decimal places.

attashe74 [19]

Answer:

Variance = 4.68

Step-by-step explanation:

The formula for the variance is:

$\sigma^{2} =\frac{\Sigma(X- \mu)^{2}}{N} \\or \\ \sigma^{2} =\frac{\Sigma(X)^{2}}{N} -\mu^{2} \\$

Where:

$X: Values \\\mu: Mean \\N: Number\ of\ values$

The mean can be calculated as each value multiplied by its probability

$\mu = 0*0.4 + 1*0.3 + 2*0.1+3*0.15+ 4*0.05=1.15$

$\frac{\Sigma (X)^{2}}{N} =\frac{(0^{2}+1^{2}+2^{2}+3^{2}+4^{2})}{5} =6$

Replacing the mean and the summatory of X:

$\sigma^{2} = \frac{\Sigma(X)^{2}}{N} -\mu^{2} \\= 6 - 1.15^{2}\\= 4.6775$
