Answer: 1/27000

Explanation:

If 3^-1 = 1/3

Then 3^-3 = 1/3^3 = 1/27

And 10^-3 = 1/10^3 = 1/1000

3^-3 x 10^-3

= 1/27 x 1/1000
= 1/27000

BIG POINTS! Please help me with this math problem. By the way, the answer is not 1 / 128 .

vodomira [7]

Answer and Step-by-step explanation:

2 * 2 * 2 * 2 * 2 * 2 * 2 = 128

2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 1024

4 * 4 * 4 * 4 * 4 = 1024

8 * 8 = 64

$\frac{128 - 1024}{1024 - 64}$

$\frac{-896}{960}$

896 and 960 both have 64 in common.

896 divided by 64 equals 14.

960 divided by 64 equals 15.

$-\frac{14}{15}$ is the answer.

OverLord2011 [107]

Answer: $(0.9460\ ,\ 0.9500)$

Step-by-step explanation:

Given : Population mean : $\mu=0.9480$

Standard deviation : $\sigma=0.0060$

Sample size : n=35

Significance level : $\alpha=1-0.95=0.05$

Critical value = $z_{\alpha/2}=\pm1.96$

The confidence interval for sample mean is given by :-

$\mu\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

i.e. $0.9480\pm (1.96)\dfrac{0.0060}{\sqrt{35}}$

$\approx0.9480\pm0.0020=(0.9480-0.0020\ ,\ 0.9480+0.0020)\\\\=(0.9460\ ,\ 0.9500)$

Hence, the required interval= $(0.9460\ ,\ 0.9500)$
