What's 1.3 repeating as a fraction

Bogdan [553]

<span>1.333333333333333.... = 4/3.

To find this:

x = 1.3333333333333...

Multiply by 10:

10x = 13.3333333333...

Subtract x = 1.3333333333333333....:

The brain volumes (cm cubed) of 20 brains have a mean of 1105.1 cm cubed and a standard deviation of 123.5 cm cubed. Use the g

kramer

Answer:

$1332.1 \:cm^3$ is neither significantly low nor significantly high.

Step-by-step explanation:

From the information given, we know that:

The mean is $\bar{x}=1105.1 \:cm^{3}$ and the standard deviation is $\sigma=123.5 \:cm^{3}$ .

The range rule of thumb says that:

$minimum \:usual \:value=\bar{x}-2\sigma\\\\maximum \:usual \:value=\bar{x}+2\sigma$

Applying these definitions, we get that

$minimum \:usual \:value=1105.1-2(123.5)=858.1 \:cm^3\\\\maximum \:usual \:value=1105.1+2(123.5)=1352.1 \:cm^3$

We note that $1332.1 \:cm^3$ is between $858.1 \:cm^3$ and $1352.1 \:cm^3$ , which indicates $1332.1 \:cm^3$ is neither significantly low nor significantly high.
