Answer:

x can be replaced by 8 and -8

Step-by-step explanation:

Given : 1: x = x:64

We have to find the value of x,

Consider 1: x = x:64

This is same as writing,

$\frac{1}{x}=\frac{x}{64}$

$\mathrm{Apply\:fraction\:cross\:multiply:\:if\:}\frac{a}{b}=\frac{c}{d}\mathrm{\:then\:}a\cdot \:d=b\cdot \:c$

$64=x^2$

Taking square root both sides, we have,

$x=\sqrt{64}$

We know $\sqrt{64}=\pm 8$

$x=\pm 8$

Thus, x has two values x = 8 and x = -8

Answer:

The distribution of average life time is approximately normallyl distributed with mean 20 hours and standard deviation of 0.4743 hours

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
