Step-by-step explanation: 10 1/2=10 2/4 2 1/2=2 2/4

10 2/4 - 2 2/4= 8. 8= 7 4/4. 7 4/4 - 4 1/4= 3 3/4.

SOS WHAT IS THE SQUARE ROOT OF 144/256?

tangare [24]

The square root is $\sqrt{\frac{144}{256}} = \frac{3}{4}$ Just square the top and bottom of the fraction. $\sqrt{144} = 12$ and $\sqrt{256} = 16$ so we have 12/16 and then we reduce to 3/4

Answer:

$\mu_{x} = 64, \sigma_{x} = 12.83$

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sample means with size n of at least 30 can be approximated to a normal distribution with mean $\mu_{x} = \mu$ and standard deviation $\sigma_{x} = \frac{\sigma}{\sqrt{n}}$

In this problem, we have that:

$\mu = 64, \sigma = 77, n = 36$

So

$\mu_{x} = 64, \sigma_{x} = \frac{77}{\sqrt{36}} = 12.83$
