Answer:

$16.2\ cm$

Step-by-step explanation:

we know that

The diagonal of a cube is equal to

$D=b\sqrt{3}$

where

b is the length of an edge of the cube

we have

$D=28\ cm$

substitute

$28=b\sqrt{3}$

$b=28/\sqrt{3}=16.2\ cm$

Given that X ~ N(120, 35). We survey samples of 25 and are interested in the distribution of X-bar. Find the z-score associated

Answer:

Option c -2.8571

Step-by-step explanation:

z-score are calculated as

$z=\frac{xbar-mean}{\frac{S.D}{\sqrt{n} } }$ .

We are given that mean=120 and standard deviation=S.D=35 as X~N(120,35).

Sample size=n=25.

We have to find z-score for x-bar=100. So,

z-score=[100-120]/[35/√25]

z-score=[-20]/[35/5]

z-score=-20/7

z-score=-2.8571.

Thus, the z-score associated with x-bar = 100 is -2.8571.
